Refrigeration Compressor

medium 302 models total

Compresses refrigerant vapour rather than air, driving the provision store and reefer cargo cooling circuits. A wrong refrigerant charge or a slipped low-pressure cutout shows up as spoiled cargo, not a tripped breaker.

What makes this type

A refrigeration compressor draws low-pressure refrigerant vapour from the evaporator side of a cooling circuit and raises it to a higher pressure and temperature so it can give up heat at the condenser, completing the vapour-compression cycle that keeps provision stores and, on reefer or reefer-container vessels, cargo holds at their set temperature. It differs from an air compressor in the medium it handles: refrigerant rather than air, at pressures and with lubricants specific to the refrigerant in use, and it runs against a suction and discharge pressure set by the cooling load rather than a fixed working pressure.

Refrigeration compressor, cycle diagram — Refrigerant circuit for a shipboard refrigeration compressor, showing the compressor, condenser, expansion valve and evaporator linked by hot discharge and cold suction lines.

Main components

Compressor body

Reciprocating compressors remain common for provision plants and smaller reefer systems, while larger cargo refrigeration plants often use screw compressors for their continuous duty and easier capacity control.

Suction and discharge valves

Spring-loaded reed or ring valves that open and close each cycle; on reciprocating units these are the component most exposed to wear and breakage.

Capacity control

Cylinder unloading on reciprocating machines, or a sliding valve on screw compressors, adjusts output to match the cooling load without cycling the whole unit on and off.

Lubrication and oil separator

Refrigerant oil circulates with the vapour and must be separated and returned to the compressor crankcase; oil carried over into the circuit reduces heat transfer at the evaporator and condenser.

Selection / Sizing

Refrigeration capacity in kW matched to the cooling load of the stores or cargo spaces served.
Refrigerant type, commonly R404A, R507 or increasingly CO2 and ammonia on newer tonnage, each with its own pressure range and oil compatibility.
Suction and discharge pressure range the compressor is rated for, since this varies significantly by refrigerant.
Number of compressors and standby arrangement, since cargo reefer plants typically run multiple units for redundancy.

Regulations / Class

MARPOL Annex VI and the Kigali Amendment to the Montreal Protocol govern which refrigerants may be used and how leaks and disposal are handled, phasing out high global-warming-potential refrigerants on newer installations. Class rules require periodic survey of refrigeration machinery serving cargo spaces, including pressure vessel and safety valve checks on the refrigerant circuit, and provision plant compressors are covered under general machinery survey requirements.

Typical faults

Fault	Consequence
Refrigerant undercharge or leak	Low suction pressure, compressor short-cycling, inadequate cooling
Worn suction or discharge valves	Reduced capacity, higher discharge temperature, risk of valve failure
Oil carryover from a failed separator	Reduced heat transfer at evaporator, low oil level trips the compressor
Low-pressure cutout bypassed or set incorrectly	Compressor runs into a vacuum, drawing in moisture or air

What to look for in a supplier

Compatibility with the vessel's existing refrigerant and oil type before any replacement unit is ordered.
Spare valve plates and gaskets available locally, since these are routine wear items on reciprocating units.
Capacity control range matching the actual load profile rather than the peak design load alone.

Log suction and discharge pressures at every watch; a slow refrigerant leak shows up in the trend long before the compressor trips on low pressure.

Common Failures & Inspection Points

Unloader solenoid failure
Oil pressure differential low
Motor winding fault

Service: Semi-hermetic for larger reefer ships; Carrier-specific oil required.

Spare Parts: Carrier: Keep valve sets and piston rings on board. Lead time: 2–6 weeks. Oil filters and gasket sets as standard ship's stores.

Strengths

Suitable for large reefer ships due to its semi-hermetic design
Specific oil requirement ensures compatibility and potentially better performance
Carrier's reputation for quality and reliability in marine refrigeration systems

Weaknesses

Unloader solenoid failure and motor winding faults have been reported
Requires specific oil, which might be more expensive or harder to find than standard oils
Oil pressure differential issues can lead to maintenance challenges

Typical Vessels: Reefer shipsContainer ships with refrigerated cargoCruise ships with extensive refrigeration needs

Decision Guide: Choose if you prioritize a reliable, semi-hermetic compressor from a well-known manufacturer for your refrigeration needs on larger vessels. Avoid if you are looking for a more versatile compressor that can use standard oils or if you have had negative experiences with Carrier's specific oil requirements.

Use Cases: Typically deployed in the refrigeration systems of large reefer ships and other vessels requiring significant cooling capacities, such as those carrying perishable goods over long distances.

42 kW cooling · 18.0 kW · Refrigerant R404A · semi-hermetic reciprocating compressor

Common Failures & Inspection Points

Valve plate cracking
Oil logging in evaporator
HP cutout tripping
Compressor overheating

Service: Semi-hermetic reciprocating; check oil level sight glass and superheat.

Spare Parts: Bitzer: Keep valve sets and piston rings on board. Lead time: 2–6 weeks. Oil filters and gasket sets as standard ship's stores.

Strengths

Compact design suitable for limited engine room space
Integrated oil level sight glass simplifies routine checks
Good part‑load efficiency typical of reciprocating units
Proven reliability in marine refrigeration applications

Weaknesses

Higher vibration and noise compared with screw or scroll compressors

Power (kW)

Type

Screw Compressor

Common Failures & Inspection Points

Slide valve actuator failure
Rotor bearing wear
Oil separator element saturation
Capacity control malfunction

Service: Screw compressor — low vibration, continuous duty. Slide valve allows 25-100% capacity. Oil change every 10000 hrs.

Spare Parts: Bitzer: Keep valve sets and piston rings on board. Lead time: 2–6 weeks. Oil filters and gasket sets as standard ship's stores.

Strengths

Low vibration and noise due to screw design, suitable for passenger comfort areas
Wide capacity control (25–100%) via slide valve enables efficient load matching
Continuous duty rating ideal for 24/7 cargo refrigeration
Relatively long oil change interval (≈10 000 h) reduces maintenance downtime
Compact footprint compared with reciprocating units of similar power

Weaknesses

Slide‑valve actuator failures have been reported, requiring careful monitoring
Rotor bearing wear can become an issue if lubrication is neglected
Oil separator element may saturate under heavy load, necessitating regular checks
Limited to R‑134a refrigerant; not suitable for vessels mandated to use low‑GWP alternatives
Capacity control malfunction can lead to reduced efficiency if not serviced promptly

Typical Vessels: Reefer container shipsSpecialized refrigerated cargo vessels (fruit, meat, dairy)Chemical tankers using low‑temperature cargo coolingFishery freezer vesselsPassenger ferries with onboard air‑conditioning

Decision Guide: Choose if: you need a reliable, low‑vibration screw compressor for continuous refrigeration on vessels that use R‑134a and benefit from wide capacity control. Avoid if: the vessel requires alternative refrigerants (e.g., R‑404A, low‑GWP blends), higher power output than 75 kW, or an oil‑free design.

Use Cases: Typically installed in cargo hold refrigeration loops for perishable goods, deck‑mounted air‑conditioning plants on passenger vessels, and auxiliary cooling systems on chemical carriers where precise temperature control and low vibration are critical.

Common Failures & Inspection Points

Vi ratio actuator failure
Rotor wear
Oil foaming
Discharge temperature alarm

Service: Variable Vi for optimal efficiency across load range. Integral oil separator. Marine-certified vibration.

Spare Parts: Bitzer: Keep valve sets and piston rings on board. Lead time: 2–6 weeks. Oil filters and gasket sets as standard ship's stores.

Strengths

Variable VI actuator provides optimal efficiency over a wide load range
Integrated oil separator reduces external component count and maintenance
Marine‑vibration certification ensures reliable operation on board ships
Compact screw design suitable for limited engine room space
Compatible with widely used refrigerants R‑134a and R‑513A

Weaknesses

VI ratio actuator can be a failure point requiring preventive maintenance
Rotor wear may increase at sustained high‑load operation
Oil foaming issues if oil quality or temperature control is inadequate
Discharge temperature alarm necessitates careful monitoring and possible derating
Limited to R‑134a/R‑513A; not suitable for CO₂, ammonia or newer low‑GWP refrigerants

Typical Vessels: Reefer container shipsDry cargo vessels with refrigerated holdsLPG carriers requiring cargo temperature controlOffshore supply vessels with HVAC/refrigeration needsPassenger ferries with onboard refrigeration

Decision Guide: Choose if you need a compact, high‑efficiency marine compressor for R‑134a/R‑513A with variable capacity and integrated oil separation. Avoid if your application requires other refrigerants, ultra‑low maintenance without actuator parts, or if budget constraints preclude the higher upfront cost of a variable‑VI unit.

Use Cases: The HSK8571 is typically installed in cargo refrigeration plants on reefer ships to maintain temperature for perishable goods, as part of HVAC systems on passenger vessels, and on offshore supply rigs where space‑efficient, marine‑qualified compressors are required for auxiliary cooling.

Bock

HGX6/1410-4S

38 kW cooling · 15.0 kW · Refrigerant R404A · open‑type reciprocating refrigeration compressor

Common Failures & Inspection Points

Suction valve leakage
Oil foaming on start
Shaft seal leak

Service: Open-type reciprocating; shaft seal is the main wear item.

Spare Parts: Bock: Keep valve sets and piston rings on board. Lead time: 2–6 weeks. Oil filters and gasket sets as standard ship's stores.

Strengths

Proven Bock brand reliability in harsh marine environments
Open‑type design allows easy access for inspection and overhaul
High displacement per cylinder gives strong cooling capacity for large cargo holds
Compatible with common marine refrigerants approved under IMO D‑2

Weaknesses

Suction valve leakage reported as a recurring failure mode
Oil foaming on start can delay commissioning after shutdowns
Shaft seal is the primary wear item and requires scheduled replacement
Higher vibration and noise compared with oil‑free screw or scroll units

Typical Vessels: Reefer (refrigerated cargo) vesselsContainer ships carrying refrigerated containersBulk carriers transporting perishable bulk cargo (e.g., fruit, meat)Offshore platforms requiring deck refrigeration

Certifications: IMO D-2

Decision Guide: Choose if: you need a rugged, high‑capacity compressor for large cargo refrigeration plants and have the maintenance capability to service shaft seals and suction valves. Avoid if: low vibration, oil‑free operation, or minimal wear‑item maintenance are top priorities; consider screw or scroll compressors instead.

Use Cases: Typically installed as part of the main cargo refrigeration plant on reefer ships, providing chilled ammonia or CO₂ cycles for multiple cargo holds. Also used in auxiliary refrigeration loops for galley/freezer spaces where a reliable, high‑capacity compressor is required.

Service: Semi-hermetic — field-serviceable motor. Check oil level at sight glass. Acid test oil every 4000 hrs.

Spare Parts: Bock: Keep valve sets and piston rings on board. Lead time: 2–6 weeks. Oil filters and gasket sets as standard ship's stores.

Strengths

Field‑serviceable motor allows on‑site repairs without removing the whole unit
Compact size suitable for limited engine‑room space
Compatible with widely used marine refrigerants (R‑134a, R‑404A)
Sight glass and oil level check simplify routine maintenance
Relatively low power consumption for its cooling capacity

Weaknesses

Valve plate cracking reported in long‑term service
Motor winding burnout can occur if overload protection is inadequate
Oil foaming at startup may require careful pre‑run procedures
Suction/discharge valve leakage possible, demanding regular leak checks
Semi‑hermetic design offers shorter life than hermetic screw units under heavy duty cycles

Typical Vessels: Reefer container shipGeneral cargo vessel with refrigerated holdsOffshore supply vessel (HVAC)Cruise or passenger ship (galley/crew refrigeration)

Decision Guide: Choose if you need a compact, 15 kW compressor for R‑134a/R‑404A with field‑serviceable motor and easy oil monitoring. Avoid if the application demands higher capacity, ultra‑low vibration screw technology, or cannot accommodate the known valve plate and motor wear issues without strict maintenance regimes.

Use Cases: Commonly installed in cargo hold cooling systems on refrigerated vessels, air‑conditioning plants on passenger ships, and small to medium refrigeration loops for provisions storage where space is limited and serviceability is valued.

Oil charge loss may lead to reduced lubrication and overheating
Coupling vibration can cause premature bearing wear
Limited capacity compared with larger screw or scroll compressors

Typical Vessels: Reefer container shipsGeneral cargo vessels with refrigerated holdsPassenger ferries and cruise ships (galley/refrigeration plant)Offshore supply/ accommodation vessels

Certifications: IMO Type Approval

Decision Guide: Choose if: you need a compact, easy‑to‑service compressor for modest cooling loads on vessels that already use R‑404A/R‑134a and value Bock’s service network. Avoid if: the plant requires high capacity, ultra‑low vibration, or must operate with low‑GWP refrigerants not supported by this model.

Use Cases: Typically installed in shipboard provision plants to supply chilled water for galley stores, in cargo hold cooling systems on refrigerated carriers, and in offshore accommodation modules where space is limited and maintenance access is essential.

Datasheet

Sabroe

SMC 108L

120 kW cooling · 45.0 kW · Refrigerant R717 (NH3) · oil‑lubricated reciprocating ammonia compressor

Common Failures & Inspection Points

Shaft seal leak
Oil separator malfunction
Liquid slugging
Valve plate damage

Service: Ammonia reciprocating; leak detection critical — NH3 is toxic.

Spare Parts: Sabroe: Keep valve sets and piston rings on board. Lead time: 2–6 weeks. Oil filters and gasket sets as standard ship's stores.

Strengths

Proven reliability in high‑pressure NH₃ service on LPG and chemical tankers
Integrated oil separator reduces oil carry‑over to the refrigerant circuit
Compact layout compared with multi‑stage screw units of similar capacity
Straightforward mechanical maintenance – familiar to most marine engineers

Weaknesses

Requires diligent leak detection and regular oil analysis due to NH₃ toxicity
Sensitive to liquid slugging; must be protected by proper suction piping and level control
Oil‑lubricated design adds routine oil change intervals versus oil‑free screw compressors
Part‑load efficiency lower than modern variable‑speed screw or scroll units

Typical Vessels: LPG carrierChemical tankerBulk liquid carrier (e.g., vegetable oil, ethanol)Refrigerated cargo vessel

Certifications: DNVABS

Decision Guide: Choose the SMC 108L when you need a rugged, well‑known reciprocating compressor for ammonia service on vessels where space is limited and maintenance crews are familiar with oil‑lubricated designs. Avoid it if low part‑load energy consumption or oil‑free operation is a priority, or when the vessel operates in environments with high risk of liquid slugging that exceed the unit’s design safeguards.

Use Cases: The SMC 108L is typically installed on LPG carriers and chemical tankers to drive the ammonia refrigeration loop for cargo temperature control. It is also used on bulk liquid carriers carrying temperature‑sensitive products where a compact, high‑pressure compressor is required and the crew has established leak‑detection procedures.
