Marine Calorifier

Alfa Laval Marine Calorifier is a compact, electrically heated hot‑water storage unit that combines a stainless‑steel heating coil and a tank to supply potable water at temperatures above 60 °C. The supplied category identifies the equipment as Hot Water Calorifier, and it is normally installed in the domestic freshwater machinery space with pumps, pressure vessel or calorifier, controls and distribution piping. In that listed role, its primary purpose is to maintain domestic water pressure or provide hot water to accommodation and service consumers. Hydrophore units and calorifiers have different functions, but both depend on sound pressure control, tanks, valves and sanitary water condition. The model designation identifies the listed configuration, but no additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. The source metadata also states power: 12.0 kW; capacity: 200-2000 L, 60-80°C. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

Common failures & inspection points

Pump, heater or control failure causes low pressure, poor hot-water supply or repeated cycling
Pressure-switch, thermostat or level faults cause unstable operation or protective trips
Air-charge loss, vessel leakage or failed non-return valves cause frequent pump starts or pressure fluctuation
Scale or internal deposits reduce heating or water-flow performance
Seal, flange or relief-valve leakage causes visible water loss and corrosion

Service & Maintenance

Inspect pumps or heaters, pressure vessel or calorifier, valves, controls, relief devices and leakage. Check pressure cycling, hot-water temperature stability and sanitary condition under the vessel maintenance program. Verify safety valves and electrical protection using approved procedures. Refer to the manufacturer documentation for the exact figure for pressure, temperature and service settings.
