The Autofridge is the highest quality low voltage refrigerator/ freezer available. It is designed specifically to withstand conditions that only the Australian Outback throws up, including rough, seemingly never-ending roads or weeks of unrelenting 40 °C heat. The Autofridge handles these challenges with ease, and handles them with the lowest power usage available (20 Ah per day).
Performance
- The Autofridge has been designed and manufactured in Australia to suit Australian conditions.
- The interior cabinet and the exterior construction of the Autofridge are white fiberglass - this colour is the best for hot climates and the integral strength of fiberglass for use in rough conditions has been proven by the long-term popularity of fiberglass for boat manufacture.
- The compressor chosen for use in the Autofridge is the latest Danfoss BD35F unit and controller. This compressor has been selected because of its remarkable efficiency, and it is supplied as a spring-housed unit - suitable for use in any off-road conditions.
- The eutectic operation of the refrigeration system allows you, the user, the luxury of knowing that in ambient temperatures of up to 32 °C, the maximum daily power consumption of your fridge is on average only 20 Ah/12 V. This of course means that you can easily determine how long you can remain stationary without flattening your battery.
Characteristics
The Autofridge comprises a compressor driven system, combined with the power-saving advantages of a eutectic refrigeration system. Eutectic fluid surrounds the four walls of the interior cabinet, acting as an 'ice bank', or cold storage compound, for the contents of the cabinet. Once the Autofridge has been pre-chilled, the eutectics mean that it need only be run for 5 hours per day (preferably 2 hours in the morning and ~ 3 hours in the afternoon) on its maximum setting to maintain the desired temperature - even in ambient temperatures of 32 °C. While the Autofridge is running, the fluid is frozen and the cabinet contents are thoroughly chilled, and can be turned off in between the run times, while the frozen eutectic fluid provides a continuous refrigeration holdover resulting in NIL power consumption during this holdover period.
The Autofridge can be operated in any of the following ways:
- As a eutectic refrigeration system - the Autofridge is run for a total of 5 hours per day - split into two separate running periods of 2 hours in the morning and ~3 hours in the afternoon. The Autofridge is turned off in the interim. Average daily power consumption for this mode of operation is approx. 20 Ah / day at 12 V.
- As a cyclic refrigeration system - the Autofridge is set on a refrigeration setting (e.g. ‘2’) on the thermostat and left to cycle on and off throughout the day. Average daily power consumption for this mode of operation is approx. 24 Ah / day at 12 V.
- As a cyclic freezer - the Autofridge is set on one of its sub-zero settings (‘5’, ‘6’ or ‘7’) on the thermostat - the higher the setting, the colder the Autofridge will cycle - and left to cycle on and off throughout the day. Average daily power consumption for this mode of operation is approx. 40 Ah / day at 12 V.
As you probably are aware, the efficiency of your vehicle or marine electrical system can greatly affect the operation of any low voltage refrigerator. How you intend to use your Autofridge and other appliances including DC lights will determine whether an auxiliary battery should be installed.
An Autofridge Power Pack (AFPP 10F) for operation of the autofridge with 240V AC is also available. |
