System Estimating..  Choosing a system fit for purpose..   

Prior to suggesting or supplying  a system, we offer an obligation free project assessment so that the package offered is the most suitable, provides the refrigeration outcomes expected in the environment nominated, and with a known power consumption.     


We load your cabinet and usage information into our 'Heat Load and Duty Estimator' to obtain data specific to your project.   

This chart and other data supplied, is then checked by our engineer and emailed back to you with our recommendations, comments and detailed quotation with estimate of FOB origin courier delivery to your address. (Star Track Australia or UPS International) 

Below:  Sample of our Estimator and a description of it's findings.

We recommend that systems be engineered to maintain required temperature in the situation nominated without exceeding a 50% duty cycle. 

< Your cabinets specific details and use: (Blue)

As we load your cabinet details the estimator instantly provides an assessment following.. 


<Your cabinets capacity and heat load in watts./Hr


Cabinet capacity is calculated in litres. (Divide litre x 28.3 to read as cubit feet if preferred.) 

<The % of run time for the use as either a freezer or fridge using the suggested Ozefridge system.

This panel is most important. The amp/ hours here are the total for a 24 hour period in the your extreme conditions. 


Plan for this energy to be available daily although most often, especially with ECO2, the daily battery drain should be far less than this figure.

Other services..

ZOOM Room! 

Now we can service customer enquiries world wide with video interaction. 
From here we can access and video components etc that makes assistance much easier to follow. 

As in this picture an obligation free 'Heat Load, Duty Cycle and Power Consumption' estimate is made specific for each project enquiry as an essential starting point.
A verification that system suggested is fit for purpose and a guide to power required in worst case situations!

This video facility puts us virtually at your side during system selection, installation and any ongoing support. (Check our 'Fridge Assist' page.)

Research and Product Development :

Test hub 12 23.png

Research and product testing is an essential activity at Ozefridge. 
This dedicated controlled environment allows testing and digital data logging under various conditions. It also provides an accurate performance and efficiency comparison of different system types while refrigerating sequentially in identical situations. 

Important note: Some countries including Australia, require that R134a gas is only handled by licensed trades-persons.
