Plate Evaporator

medium 102 models total

A plate evaporator uses stacked titanium plates to flash seawater into freshwater vapour under vacuum, run on jacket cooling water from the main engine, trading the shell-and-tube evaporator's robustness for a smaller footprint and faster response to load changes.

What defines a plate evaporator

A plate-type freshwater generator produces distilled water from seawater by flash evaporation under vacuum, using low-grade heat -- typically 70 to 85°C jacket cooling water drawn from the main engine -- rather than dedicated steam. The vacuum, held by an ejector or a vacuum pump, lowers the boiling point of seawater so evaporation happens at engine cooling water temperature instead of 100°C. What sets the plate type apart from the shell-and-tube evaporator is the heat exchange surface: gasketed or brazed plates instead of a tube bundle. Plates give more heat transfer area per unit volume, respond faster when engine load and cooling water temperature change, and are easier to open up and inspect for scale, but the gasketed versions carry more seals that can leak and the plate pack is less tolerant of thermal shock than a tube bundle.

Plate evaporator flow scheme
Flow scheme of a plate-type freshwater evaporator: seawater feed flashes to vapour across the plate pack heated by engine jacket water, the vapour is demisted and condensed by cooling seawater, leaving as distillate while brine and the vacuum ejector complete the circuit.

Main components

Plate heat exchanger sections

Usually two plate packs in one shell: an evaporator section heated by jacket water, and a condenser section cooled by seawater, arranged so vapour rising off the evaporator plates condenses on the condenser plates without further pumping.

Vacuum system

A steam or seawater-driven ejector, or an electric vacuum pump on newer units, holds the shell at the vacuum needed for the jacket water temperature available -- the lower the heat source temperature, the deeper the vacuum required.

Salinometer and dump valve

A conductivity sensor on the distillate outlet continuously checks salinity; if it rises above the set point an automatic three-way valve dumps the batch to bilge instead of the potable water tank.

Brine and distillate pumps

The brine pump removes concentrated, unevaporated seawater from the shell; the distillate pump draws off the condensed freshwater. Both run under vacuum conditions, which makes their seals and NPSH margin more demanding than a normal centrifugal pump duty.

Selection and sizing

  • Daily freshwater output required against crew and technical water demand, plus a margin for reduced engine load in port.
  • Available jacket water temperature and flow at the lowest engine load the vessel regularly operates at, since output falls sharply below a minimum temperature.
  • Seawater temperature range for the trading area -- warm seawater reduces the achievable vacuum and therefore output.
  • Materials of construction: titanium plates for seawater and vapour-side corrosion resistance, versus lower-cost alloys accepted only in benign trades.
  • Space and headroom for opening the plate pack for cleaning without lifting it out of the engine room.

Regulations and class

Potable water produced aboard falls under flag state and port health requirements for drinking water quality, and class rules require the freshwater generator's salinity alarm and automatic dump to potable tank be demonstrated at survey. Where the evaporator draws from the same jacket water circuit as the main engine, class also checks that a fault in the evaporator cannot compromise main engine cooling -- an isolating arrangement or a dedicated heat exchanger loop is required on many designs for exactly this reason.

Typical faults

FaultCauseConsequence
Falling freshwater outputScale build-up on the evaporator plates, worse in warm or hard seawaterReduced heat transfer, eventually output too low to meet demand, requiring plate pack acid cleaning
Repeated automatic dump to bilgeSalinometer drift, or brine level too high carrying droplets into the distillateLoss of produced water, and if the alarm is disabled or ignored, a real high-salinity batch reaching the potable tank
Loss of vacuumWorn ejector nozzle, air leak at a plate gasket, or vacuum pump seal wearEvaporation stops or output collapses even with normal jacket water temperature
Gasket leak between platesGasket age-hardening or incorrect tightening torque after cleaningCross-contamination between brine and distillate sides, or external leak into the bilge

What to look for in a supplier

  • Plate material certificate (titanium grade) matching the seawater corrosivity expected on the trading route.
  • Guaranteed output curve against jacket water temperature and seawater temperature, not just a single nominal figure.
  • Gasket spares in the exact plate profile, since gaskets are not universally interchangeable between makers.
  • Documented cleaning procedure and access arrangement for opening the plate pack in place.

Output drops noticeably in port whenever the main engine idles at low load -- that is the jacket water temperature falling, not a fault, and running the auxiliary boiler or an electric heater to supplement heat is the normal workaround rather than something to trace as a defect.

Strengths
  • Titanium Grade 1 plates give excellent corrosion resistance and long service life
  • Wide capacity range (0.5–100 m³/24 h) via modular JWP‑16, JWP‑26 and optional series
  • Low vacuum operation (85‑95 % of ambient) reduces steam consumption
  • Flexible jacket‑water temperature control (55‑95 °C) allows optimisation with ship waste heat
  • Compact weight for its output (600‑955 kg for the larger JWP‑26) compared with multi‑effect units
Weaknesses
  • Requires a minimum seawater inlet pressure of 3 bar, limiting installation on low‑pressure pump systems
  • Titanium plates and ejector hardware raise capital cost relative to aluminium or stainless‑steel exchangers
  • Scaling (calcium carbonate, magnesium hydroxide) must be managed with regular chemical cleaning every 3–6 months
  • Maximum ejector outlet pressure of only 0.8 bar restricts integration with high‑pressure condensate systems
  • Weight may still be significant for small vessels where space and displacement are at a premium
Typical Vessels: Container shipsCrude oil & product tankersBulk carriersCruise linersOffshore supply vesselsLNG carriersNaval auxiliary ships
Certifications: IMO Type ApprovalDNV GL Classification
Decision Guide: Choose if the vessel needs reliable, high‑purity freshwater at capacities up to 100 m³/24 h, has adequate seawater pressure (≥3 bar) and can supply waste heat for jacket water. Avoid on small craft with limited power or low seawater pressure, or when upfront budget is a primary constraint.
Use Cases: Installed as the main desalination plant on long‑range merchant vessels to supply crew galley water, boiler feedwater pre‑treatment and HVAC systems; also used on offshore platforms where high‑quality water is required for process and living quarters.

Service: Smaller capacity variant. Same anti-scaling treatment required. Clean plates when output drops below 70%.
Spare Parts: Alfa Laval: keep injection nozzles and oil filters on board. Lead time: 1–4 weeks
Strengths
  • Titanium Grade 1 plates provide excellent corrosion resistance and long service life
  • Compact, low‑weight design suitable for vessels with limited space
  • Operates at high vacuum (85‑95 % of ambient) giving good energy efficiency
  • Flexible jacket‑water temperature range (55–95 °C) allows optimisation in varying sea conditions
  • Modular capacity – can be upgraded to larger JWP series if future demand grows
Weaknesses
  • Requires a minimum seawater inlet pressure of ~3 bar for the ejector, limiting use on low‑pressure systems
  • Single‑stage design limits maximum output; not suitable for high‑capacity vessels (>20 m³/24 h)
  • Titanium plates and specialised gaskets increase initial capital cost
  • Fouling (scale, salt deposits) can reduce performance quickly – needs cleaning when output falls below ~70 %
  • No built‑in redundancy; a failure shuts down fresh water production until repaired
Typical Vessels: Coastal tankersProduct carriers (small to medium)Offshore supply vesselsFerries and cruise ships under 10 000 gtResearch / survey vessels
Certifications: IMO Type ApprovalDNV Class approval
Decision Guide: Choose if the vessel needs up to ~10 m³ of fresh water per day, has limited installation space, operates in warm seas where jacket‑water temperature can be kept above 55 °C, and can provide at least 3 bar seawater pressure for the ejector. Avoid if the required daily output exceeds 15–20 m³, the ship’s seawater system cannot guarantee the minimum pressure, or maintenance resources are insufficient to manage regular plate cleaning.
Use Cases: The AQUA S‑type is typically installed on small to medium commercial vessels and offshore platforms where a compact, corrosion‑resistant desalination unit is required for crew water supply, galley use, and HVAC. It is also favoured on ships that operate in warm waters where the flexible jacket‑water temperature improves efficiency.

  • DPU-36 (10-55 m³/24h)
Common Failures & Inspection Points
  • Area: Plate scaling and corrosion (calcium carbonate, magnesium hydroxide, calcium sulfate deposits)
    Check: Every 6 months: visually inspect plate packages, soak with mild acid solution (e.g. Descalex), use soft brush for gentle cleaning, check for pinholes/cracks, monitor ring surface damage (pitting, scratches, erosion)
  • Area: Gasket wear and sealing leaks (neoprene coating flaking, gasket damage)
    Check: Every 12 months: visually inspect gasket surface damage (wear, deformation, traces of salt crystallization), mark leak points during pressure test, replace worn gaskets, clean and dry seal surfaces before re-fastening
  • Area: Ejector vacuum loss and air leaks (ejector nozzle wear, poor vacuum retention, seal wear)
    Check: Weekly check vacuum gauge (shall maintain 85–95%); if difficult: air pressure loss test (if vacuum drops >2% in 8 h = leak present). Remove inspection plug, inspect ejector throat with flashlight, remove deposits with scraper, ejector pump inlet pressure must be ≥3 bar
  • Area: Demister contamination and salt carryover (demister blocked by salt deposit → high salinity)
    Check: Every 6 months: visually inspect demister element (blockages, salt build-up), test condenser for tube leaks (pressure test), at high salt content: chemically clean or replace condenser and demister. Monitor brine level via sight tube
  • Area: Salinometer sensor contamination and incorrect quality measurement (salt content sensor contaminated, calibrated incorrectly, electrode deposits)
    Check: Daily: check salinometer reading (shall be <10 ppm); if measurement fault: clean sensor with dry brush, NEVER touch with bare hands, check electrodes for contamination, if necessary descale with solvent. Target: salt content of distillate <10 ppm
  • Area: Hygiene and biofilm formation in pipelines/tank (legionella risk, microbial contamination during storage)
    Check: Every 3 months check tank water quality (microbial count); perform monthly CIP cleaning (cleaning-in-place), flush pipelines with biocide/chlorine, check tank cover for light ingress/contamination, maintain freshwater temperature ≥55°C to prevent legionella proliferation

    Check: Every 6 months: visually inspect demister element (blockages, salt build-up), test condenser for tube leaks (pressure test), at high salt content: chemically clean or replace condenser and demister. Monitor brine level via sight tube
  • Area: Salinometer sensor contamination and incorrect quality measurement (salt content sensor contaminated, calibrated incorrectly, electrode deposits)
    Check: Daily: check salinometer reading (shall be <10 ppm); if measurement fault: clean sensor with dry brush, NEVER touch with bare hands, check electrodes for contamination, if necessary descale with solvent. Target: salt content of distillate <10 ppm
  • Area: Hygiene and biofilm formation in pipelines/tank (legionella risk, microbial contamination during storage)
    Check: Every 3 months check tank water quality (microbial count); perform monthly CIP cleaning (cleaning-in-place), flush pipelines with biocide/chlorine, check tank cover for light ingress/contamination, maintain freshwater temperature ≥55°C to prevent legionella proliferation

Marine and industrial freshwater desalination via forced circulation evaporation
Common Failures & Inspection Points
  • Area: Scale and mineral deposit formation on evaporator and condenser plate surfaces reduces heat transfer efficiency and system performance
    Check: Visually inspect evaporator and condenser plate bundles for scale buildup at semi-annual intervals (twice yearly). Remove man-hole and bottom covers of heat exchanger to examine tube condition and check for Neoprene coating exfoliation. Remove condenser covers to verify no fouling of cooling tubes with sludge. Perform chemical analysis of evaporator liquid for silica, calcium, and mineral content to confirm descaling need. Use chemical descaling agents (e.g., sodium polysulphate with anti-foam compounds) every 6-12 months or as needed based on salt content.
  • Area: Vacuum system leakage and loss of pressure reduces evaporation efficiency and prevents system operation
    Check: Perform leak test after maintenance or if vacuum maintenance difficulty occurs. Standard: vacuum must not fall more than 2% in 8 hours under normal operation. If vacuum drop exceeds 2% in 8 hours, inspect and seal deteriorated packings and joints immediately. Use pressure/vacuum gauges to monitor system continuously during operation. Check all joint connections, flange seals, and packing glands for visible leaks or weeping. Document baseline vacuum readings and monitor trending to detect progressive leaks.
  • Area: Demister malfunction causes seawater droplet carry-over resulting in high salinity output unsuitable for human consumption
    Check: Inspect wire mesh demister for salt encrustation, clogging, or physical damage quarterly. Clean demister using fresh water spray and verify mesh integrity (holes should be visible under backlight, no collapsed sections). Check output salinity continuously: should be 2-10 ppm adjustable set point (alarm if exceeds 4 ppm per IMO standards). If salinity exceeds threshold, demister must be cleaned immediately or replaced. Monitor vapor quality visually for excessive liquid carryover (droplet mist instead of clean vapor).
  • Area: Condenser tube/plate leakage contaminates distillate with seawater, raising salinity above acceptable limits (4 ppm maximum)
    Check: Perform hydrostatic pressure test on condenser quarterly using 1.5x normal operating pressure with fresh water to verify tube/plate integrity. Visual inspection: check condenser cooling jacket for visible salt deposits or staining indicating past leakage. Monitor distillate salinity continuously using calibrated salinometer (2-10 ppm range); if salinity rises above set point despite normal demister operation, investigate condenser for internal leaks. Replace any corroded or perforated condenser tubes/plates immediately. Test sea water cooling circuit for blockage that may cause condenser overpressure.
  • Area: Titanium and stainless steel plate surface corrosion and micro-pitting under seawater exposure degrades material integrity and may cause perforation
    Check: Perform visual external inspection annually for visible corrosion, discoloration, or surface attack on all seawater-exposed titanium and 316L stainless steel components (evaporator bundle, condenser bundle, connecting lines). Internal inspection every 3-5 years: remove plates and examine for scaling, biofouling, or micro-pitting using magnification if needed. Use non-abrasive cleaning (avoid sand blasting or steel wool) to protect titanium passivation layer. For seawater-contact areas, specify titanium or superduplex (2507) material at maintenance: avoid lower-grade stainless in salt-spray zones.

SeaWaterDistiller SWD 10 ✓ verified
Application
Marine freshwater generation from seawater
Common Failures & Inspection Points
  • Area: Scale and mineral deposit formation on evaporator and condenser plate surfaces reduces heat transfer efficiency and system performance
    Check: Visually inspect evaporator and condenser plate bundles for scale buildup at semi-annual intervals (twice yearly). Remove man-hole and bottom covers of heat exchanger to examine tube condition and check for Neoprene coating exfoliation. Remove condenser covers to verify no fouling of cooling tubes with sludge. Perform chemical analysis of evaporator liquid for silica, calcium, and mineral content to confirm descaling need. Use chemical descaling agents (e.g., sodium polysulphate with anti-foam compounds) every 6-12 months or as needed based on salt content.
  • Area: Vacuum system leakage and loss of pressure reduces evaporation efficiency and prevents system operation
    Check: Perform leak test after maintenance or if vacuum maintenance difficulty occurs. Standard: vacuum must not fall more than 2% in 8 hours under normal operation. If vacuum drop exceeds 2% in 8 hours, inspect and seal deteriorated packings and joints immediately. Use pressure/vacuum gauges to monitor system continuously during operation. Check all joint connections, flange seals, and packing glands for visible leaks or weeping. Document baseline vacuum readings and monitor trending to detect progressive leaks.
  • Area: Demister malfunction causes seawater droplet carry-over resulting in high salinity output unsuitable for human consumption
    Check: Inspect wire mesh demister for salt encrustation, clogging, or physical damage quarterly. Clean demister using fresh water spray and verify mesh integrity (holes should be visible under backlight, no collapsed sections). Check output salinity continuously: should be 2-10 ppm adjustable set point (alarm if exceeds 4 ppm per IMO standards). If salinity exceeds threshold, demister must be cleaned immediately or replaced. Monitor vapor quality visually for excessive liquid carryover (droplet mist instead of clean vapor).
  • Area: Condenser tube/plate leakage contaminates distillate with seawater, raising salinity above acceptable limits (4 ppm maximum)
    Check: Perform hydrostatic pressure test on condenser quarterly using 1.5x normal operating pressure with fresh water to verify tube/plate integrity. Visual inspection: check condenser cooling jacket for visible salt deposits or staining indicating past leakage. Monitor distillate salinity continuously using calibrated salinometer (2-10 ppm range); if salinity rises above set point despite normal demister operation, investigate condenser for internal leaks. Replace any corroded or perforated condenser tubes/plates immediately. Test sea water cooling circuit for blockage that may cause condenser overpressure.
  • Area: Titanium and stainless steel plate surface corrosion and micro-pitting under seawater exposure degrades material integrity and may cause perforation
    Check: Perform visual external inspection annually for visible corrosion, discoloration, or surface attack on all seawater-exposed titanium and 316L stainless steel components (evaporator bundle, condenser bundle, connecting lines). Internal inspection every 3-5 years: remove plates and examine for scaling, biofouling, or micro-pitting using magnification if needed. Use non-abrasive cleaning (avoid sand blasting or steel wool) to protect titanium passivation layer. For seawater-contact areas, specify titanium or superduplex (2507) material at maintenance: avoid lower-grade stainless in salt-spray zones.

Common Failures & Inspection Points
  • Scale or fouling on evaporator surfaces caused by seawater concentration or poor treatment, resulting in reduced freshwater production
  • Loss of vacuum caused by air leakage, ejector wear or poor seawater flow, resulting in higher boiling temperature and low capacity
  • High distillate salinity caused by carry-over, damaged seals or salinity-sensor faults, resulting in product-water rejection
  • Condenser fouling caused by scale or debris, resulting in poor condensation and reduced vacuum performance
  • Pump, valve or seal leakage caused by wear or corrosion, resulting in unstable feed, visible leakage or inability to maintain normal operation
Service: Trend freshwater production, salinity, vacuum, temperatures and seawater flow against established normal operation. Inspect and clean evaporator and condenser surfaces using approved methods and maintain seawater strainers. Check ejectors, pumps, valves and vacuum leaks when production falls. Verify the salinity cell and automatic diversion after maintenance. Prevent excessive scaling by following the vessel's operating and treatment procedure. Refer to the manufacturer documentation for the exact figure for vacuum, temperature, cleaning and salinity limits.
Spare Parts: Keep plate gaskets or seals, salinity-cell service parts, ejector nozzles, pump seals, valve kits and manufacturer-recommended heat-transfer components. Strategic spare plates or a replacement salinity sensor may be appropriate for critical vessels. Confirm materials and parts from exact model documentation.
Use Cases: Freshwater production for accommodation and technical use on merchant ships and offshore vessels using waste heat or another approved heating source.

Common Failures & Inspection Points
  • Scale, membrane fouling, biological growth or dirty optical surfaces reduce treatment capacity or water quality
  • Pump, vacuum, lamp, blower or power-supply faults cause low production, low treatment intensity or shutdown
  • Conductivity, salinity, level or treatment sensors drift and cause false acceptance, rejection or alarms
  • Seal, gasket or piping leakage causes loss of pressure, vacuum or visible water leakage
  • Pretreatment, strainer or discharge blockage causes unstable flow and poor process performance
Service: Inspect feed and discharge paths, strainers, pumps, treatment elements, monitoring and diverting arrangements. Trend production, pressure and water quality where applicable and keep pretreatment equipment clean. Prevent doubtful product water or inadequately treated effluent from entering the wrong system. Refer to the manufacturer documentation for the exact figure for pressure, cleaning, dosing and quality criteria.
Spare Parts: Carry filters, strainers, pump seals, membrane or UV parts where applicable, sensors, valve parts, blower service items and approved treatment consumables.
Strengths
  • Compact size – fits in tight engine‑room spaces
  • Low power consumption compared with multi‑effect units
  • Modular plate design allows quick on‑board replacement of fouled plates
  • Integrated ejector condenser reduces moving parts and maintenance
  • Proven track record on a wide range of commercial vessels
Weaknesses
  • Plate scaling can limit performance if feed water pretreatment is inadequate
  • Ejector wear may require periodic overhaul
  • Gasket deterioration leads to occasional leaks and replacement intervals
  • Limited maximum daily output (typically 5‑15 m³/day) versus larger multi‑effect plants
  • Performance sensitive to inlet seawater temperature fluctuations
Typical Vessels: Product TankerContainer ShipBulk CarrierCruise VesselOffshore Supply VesselNaval Auxiliary
Decision Guide: Choose if you need a reliable, space‑saving freshwater generator with moderate capacity and easy plate maintenance. Avoid if the vessel requires very high daily water production or operates in waters with extreme hardness where scaling risk is high.
Use Cases: Freshwater production, potable-water conditioning, hydrophore service and sewage treatment.
