Temperature control and switch panel: (Standard on A480 & AW480 units)
The AW480 and A480 models both include control panels mounted on the front but on a relocatable stainless steel plate.(Remote location kit is optional) Au$80.00
Controller provides the following standard features:
The Ozefridge ‘Sure-Thaw’ eutectic control method.
The digital controller is actually sensing the eutectic mass’s temperature allowing the system to refreeze the eutectic mass before cutting off, then thawing correctly (through phase change) before restarting. This ensures it operates truly as a eutectic system.
The controller is easily programmed with memory retention. It has a large LED display along with a compressor run / delay indicator.
The LED is a fault indicator, flashing a sequence if a problem occurs. (Details of the indicated sequence are in the manual)
The left side switch is simply an on / off switch. ‘Off’ allows the system to ‘Sleep’.
The ‘Manual / Auto’ switch is normally on Auto. Should a controller problem occur or the fridge is being loaded, then ‘Manual’ can be used. This bypasses the control system and allows the unit to run manually.
The “Air / Water’ switch allows the automatic pump to be turned off. (AW480 only)
The digital controller is water proof.
Couplings, Power and Refrigeration:
All electrical, water cooling and refrigeration couplings are located on the right side of the unit.
Schraedar valves are fitted for easy service access.
Refrigeration valves allow system pump-down.
A decal with coupling legend, details connections.
Separate fuses protect the pump and DC outlets. (AW480)
ECO2 power management system is now standard with both the A480 and AW480 models. (see details on ‘Cabinet Tips’ page)
Mains Power Converter:
This 250 watt power converter accepts 240 VAC and 12VDC. (Connections supplied) It can remain connected to both AC and DC power as it automatically chooses to operate from the highest voltage presented. This solid state converter usually is fitted on the unit and is water proof. Price $180.40.
Standard system protection on both models:
On all models the motor driver’s fail-safe provides the following protection: (After cut-out, restart is automatically attempted every 60 seconds)
Low voltage and high voltage cut-out when on DC power supplies protects for compressor and batteries.
Compressor over-load and over temperature cut-out.
Compressor soft start. Six speed stepped ramp up eliminates harmful current rush and high consumption when starting.
Start delay after any power disruption. (Prevents damaging rapid start attempts if the power supply is erratic.)
Externally located, fuse protected power terminals for pump supply. (AW480 only)
Spike arrestor to clamp and prevent any transient high voltages causing damage.
External terminals for DC connection.
Condenser thermostatically controlled to prevent over condensing. Fan speed varies on both A480 and AW480. The AW480 water pump cuts off automatically when not needed.
Automatic compressor speed ramp up to maintain highest possible refrigeration output as evaporator temperature lowers. No start load.
Models A480 and AW480 have LED fault indicator to advise if the system has defaulted. (Six warning sequences, all described in the operators manual
Hermetic Compressor: (NOW WITH FIVE YEAR WARRANTY)
Since 2010 when Danfoss stopped manufacturing their BD range of compressors, we now only provide systems powered by the proven Ozefridge Hermetic BE90 compressor for the A480 and AW480. The BE90 compressor has greater capacity than the now obsolete Danfoss manufactured BD80, and much greater capacity than the old BD50 and BD35.
To reduce stress on the motor driver (electronic unit) these compressors have soft start and transient voltage protection.
The success of the BE90 has allowed us to now offer a 5 year compressor warranty.
Using a much larger compressor increases power draw whilst running but a proportionate decrease in running time means that the BE90 does the job much faster without using any more power overall and the compressor is doing it easy. This is particularly important with the optional ECO2 included as more thermal energy can be stored during periods of abundant power, resulting in lower overall demand on battery(s) at later times.
This Ozefridge engineered condenser has two separate circuits. One circuit allows cooling ( yellow) of the refrigerant like a normal condenser, while the second circuit (blue) allows water to cool the actual condenser fins and therefore the refrigerant without having any direct contact with the refrigerant galleries. The common problem of stray current corrosion (electrolysis) is eliminated. The condensers are from cupro-nickel and conformal coated.
Able to operate as an air only condenser with twin fans or air plus water cooling, ensures proper condensing in any environment especially tropical.
Micro Pump Kit: (Included with AW480 condensing unit)
The P3 micro pump kit includes a 12 volt centrifugal micro-pump, ten meters of food grade vinyl tubing and check valve. This kit is supplied standard with each AW480 Package. Recycling your fresh water is a popular, harmless and trouble free method. Using raw water can result in increased maintenance and electrolysis damage.Pump uses less than 00.4a/h.
