12-24 volt fan cooled refrigeration units suitable for mounting in new or existing ice boxes. The fan cooled compressor can be mounted up to two metres away from the evaporator box or plate. Box type ‘O’ evaporators provide an internal freezer compartment as well as cooling the entire refrigeration compartment. Units are supplied pre-gassed with re-openable quick fit connectors for ease of installation. A choice of ‘O’, ‘L’ and flat evaporators are available. Flat evaporators can be carefully formed to suit box size.Low voltage cut off and radio interference suppression are fitted as standard. Temperature is adjusted by a rotary thermostat incorporating an on/off switch. Connection of the evaporator plate to the compressor requires only a 30mm hole to be drilled in the ice box compartment wall. Utilises R134A ozone friendly refrigeration gas.Suitable for use with the 381902 AC/DC converter.NB:1) Reduce maximum box volume by 10 - 20% in tropical conditions.2) Freezer volume is calculated at approximately one third of the refrigerator volume capability.3) Freezer thermostat required if used as freezer.4) Average power consumption calculated at +6ºC in refrigeration space using a typical cooler box with standard insulation at an ambient temperature of +22ºC
