Just a few years ago, boat owners could only dream of having a deep-freezer
on board. With new developments in refrigeration technology today that
dream has
It is important that the refrigeration unit chosen can maintain a sufficiently low and constant temperature in all conditions. If the freezer temperature is allowed to fluctuate, food quality deteriorates quickly. The ideal temperatures are -12 to -16°C for normal freeze storage and -18 to -22°C for long-term storage. Isotherm Large and Jumbo evaporators have extra large freezing surfaces that can be bent so that cooling energy can be radiated from all four sides. The Isotherm ASU Magnum model is available with a holding plate suitable for freezers and adjusted to -18°C, but it produces less stable temperatures compared to the radiation type evaporator. To achieve an even freezing effect within the box, we recommend the powerful Large or Jumbo evaporators. To determine the ideal size for your boat, divide recommended maximum refrigeration volume by 3 and order an extra freezer thermostat kit. The size of evaporator should be chosen so that it can be shaped to fit at least two of the sides of the box. The evaporator, which is made of malleable aluminium enabling it to
be shaped to conform to the inside of the box, is available in sizes
for freezers of up to 250 litres (9 cu. ft.). Temperature is regulated
by means of a traditional thermostat; the ASU sensing feature, which
switches to full effect only when the engine is running,

The
ever-expanding range of fresh, semi-prepared and ready-to-eat frozen
foods means better meals can be prepared with much less effort. Just
imagine, hours previously spent in the galley could be used to enjoy
the sailing instead.
