Natural Refrigerants


Energy efficiency is important for two reasons: it reduces running costs and supports the environment. Business with energy efficient commercial refrigeration solutions will pay far less in energy bills. Energy efficient commercial refrigeration units are typically built to a much higher standard of quality than their cheaper, less energy efficient alternatives and this means that they will last far longer. Over the course of an energy efficient fridge’s long lifetime, you can accrue savings that will easily offset the extra money spent in their initial purchase. The benefits of an energy efficient commercial refrigeration unit extend beyond monetary savings, however; when you opt for an energy efficient option, you can rest assured knowing that your business operates in an environmentally conscious manner.

Our environmental management policy is one of our highest corporate priorities and places us amongst the leaders in our industry. We are recognised as one of the pioneering companies in Australia who have helped to make the business case for natural refrigerants as alternatives to HFCs, one of the organisations that have played a critical role in advancing the adoption of natural refrigerants in our country.

Throughout the ever changing Refrigeration & HVAC industry, we at A.J. Baker & Sons have continually adapted to meet the challenges of the shift from CFC based refrigerants to HCFC/HFC Refrigerants, the use of natural refrigerants, the Analogue to Digital phase for sophisticated refrigeration controls. We are now strongly committed to the introduction and roll out of natural refrigerants. To date, including all the past, current and future ordered projects, we have a total number of more than 300 supermarket installations using R744 refrigerant (Carbon Dioxide, GWP 1, safety classification A1, non-toxic, non-flammable).

We have been involved in the design and installation of transcritical CO2 supermarket projects for five years. Since the first project in 2013, the company has been involved with 22 installations in Australia. This is with both multinational clients and independent supermarket owners.

We partner with the Epta Group, and by utilising their European expertise and our company’s skills, we have been able to apply the technology to Australian conditions. We see that transcritical CO2 is the way forward for the supermarket industry in this country, with the impact of the European phasedown of HFCs, and the reduction of HFC import quotas in Australia.
