Let us help you to get it right!..

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 information into our 'Heat Load and Duty Estimator' to obtain specific data for 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 which will include cost of tracked courier delivery to your address. (TNT in Australia and UPS International)

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

< In this top panel we load your cabinets specific details and the temperature of your maximum anticipated environment: (Yellow)

As we load your cabinet details the estimator instantly provides the information we need to enable us to make a proper assessment and system recommendation.




<This panel calculates your cabinets capacity and hourly heat load in watts. (Multiply watts by 3.41  to read as BTU's)


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

<This panel calculates the % of run time for the use as either a freezer or fridge using an Ozefridge Eutectic system.

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

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

We suggest planning for this amount of energy to be available daily although most often, especially with ECO2, the daily battery drain should be far less than this figure.

Please note, this is an estimating tool. 


The above Heat Load, Duty Cycle & Power consumption estimating spread sheet is a product of, and sole property of Ozefridge and only relates to estimates using Ozefridge Eutectic systems and assumes an insulation factor of R5 per 25mm thickness.
