    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$80.00Panel

     

     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)

    .

    OPTIONS:

    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. 

     

     

    FEATURES:

    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 2011 when Danfoss stopped manufacturing their BD range of compressors, we now only provide systems powered by the proven Ozefridge Hermetic BE50 for the AS450 or the 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. The success of the BE50 and 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.

    Condenser:

     Sketch of Condenser (Plan View)
    Ozefridge Multi-function condenser: (180mm x 180mm x 60mm. Conformal coated) AW480 only.

     

    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.

    Manufacture and Distribution:

    Our assembly process lines provide a clean and practical environment for the manufacture of these precision products. Completed systems are coupled, evacuated, and tested with their covers off providing access for leak testing and quality control inspection.

    Completely Australian made in Victoria. 

    The assembled system packages are again test run and inspected with individual system aspects documented.

    Quality control is top priority and, along with correct engineering, is the reason why Ozefridge has developed a reputation as a manufacturer of excellent products and backed with unequaled service.

    Packaging is important as systems are sent world-wide. Components are bubble wrapped then packed in a sturdy carton with air-bubble packers to prevent shipping damage. Australian delivery is via *Interparcel.com.au,  Internationally via UPS or DHL.  (*Highly recommend.)

    IMPORTANT:

    Ozefridge Industries Pty. Ltd. manufactures refrigeration system components to be installed by others and into a cabinet that has insulation properties etc. that we can not be assured of or have any control over. We offer our best assistance in choosing a system but do not guarantee cabinet temperature outcomes or the system’s ability or performance in this or any other quotation or statement.

    WARRANTY:

    Ozefridge provides a minimum of 12 months warranty subject to the conditions described in the owners manual.

    Five year compressor Warranty. This warranty is limited to the supply of replacement parts by post or a complete unit rebuild if the unit is returned to Ozefridge. We do not reimburse costs incurred as a result of work carried out by others.

    Please also note: *Although the Ozefridge system can be easily installed as a DIY project by following instructions in the owners manual, some countries including Australia require that the refrigeration pipe coupling etc., be done by a licensed person.

    CONSIDERATIONS

    Refrigeration systems operating under extreme conditions require specific engineering and build considerations to enable performance as expected.

    Typically they must withstand erratic power supplies of different voltages, rough movement, high ambient temperatures, corrosive environments, extreme angles etc., all whilst performing efficiently and quietly. Built-in fail-safe is essential, but battery power consumption is usually most important.

    Each application of marine refrigeration is somewhat unique, therefore we prefer to interact with our clients and address needs individually.
    Buying a refrigeration system off the shelf or without first addressing the relevant issues, will most likely end in tears!

    WHY OZEFRIDGE?

    Multi-voltage eutectic refrigeration is all we do and we do it very well. At Ozefridge our manufacturing standards are focused on marine application where users demand best possible materials, build quality and performance.

    Service, support and warranty? ……..24 / 7 but best ask an Ozefridge owner.
