Marine Refrigeration
We offer two types of marine refrigeration:
- Plate Type Refrigeration
- Eutectic Refrigeration
Both have advantages depending on the owners usage patterns.
Most refrigeration systems uses a compressor to compress gas. The gas expands in the evaporation plate or tank causing it to cool. This cooling removes the heat from objects in the refrigerator or ice box. This process does not cool the objects, it removes the heat from them and transfers this heat to the evaporation plate or eutectic tank.
A refrigeration system with thin evaporation plates will cycle many times a day, sometimes up to 20 times. The compressor will run longer if the thermostat is turned down towards the coolest setting. Heat in objects is transferred to the evaporation plate each time it cycles. The compressor operates frequently because the thin evaporation plate is unable to store the cold.
A eutectic system still uses a compressor but incorporates a tank filled with liquid that continually freezes and then defrosts. As the liquid freezes in the tank, its cooling energy is stored. This stored cooling ability is then released as the tank defrosts drawing heat from objects in the cool box. When the tank has almost defrosted the compressor starts again to freeze the liquids and repeat the process. This process is called a Eutectic phase.

Refrigeration Chest - Top Loading Build In
The Isotherm build-in fridge is an ideal choice where a top loading unit is required, ready to be installed complete with refrigeration cabinet.
This unit is purpose built for marine use, has a stainless steel inner liner and the capability of operation at up to 30 Deg angle of heel.
The Danfoss air cooled compressor unit is connected to the base of the ice chest and is supplied with 1.5m of flexible tubing for remote mounting if required.

Refrigeration Condensing Units
Danfoss compressor complete with condenser, tubing and quick connect couplings supplied as a replacement part for Isotherm refrigeration units.
There are two models of condensing units one model includes a fan and the other model has a static condensor. Although they are factory pre-gassed, the complete system must be evacuated and re-charged with ozone friendly R134A refrigerant upon replacement.
These units are very reliable and have been used for many years and only require an evaporator and starter module to get them running.
