Within the HVAC industry across Melbourne and Australia wide, there is an obligation for all companies to adhere to the Montreal protocol. This protocol ensures that all HVAC technicians are following guidelines set out by the UN, and policies determined by our Nation’s government, to ensure the industry as a whole, is working towards practices that have a lower environmental impact. 

At Chatfield OzCool, we choose to work with like minded partners, and service businesses that are dedicated to investing in reducing their environmental impact. Through our dedication to staying up to date with new technologies and processes, we want to be able to not only offer the bare minimum of what is required to improve a company’s environmental impact, but strive to help that business set and achieve new standards for their environmental policies.  

Faced with future targets that will include reducing the amount of Hydrofluorocarbon (HFCs) imported into Australia, a lot of businesses are now planning ahead, and starting the process of reducing their GWP emissions as soon as possible, to be able to adapt when the global HFC phase-down starts to tighten.

One such example of this is our work with 7Eleven stores across Victoria. 7Eleven are dedicated to exploring innovative ways to operate, with the aim of reducing their carbon emissions. 

We have worked with 7Eleven across a number of sites to adjust refrigeration equipment to be able to use a gas with a much lower GWP score than the industry standard. 

For a long time R404A is the refrigerant gas that is commonly used in low and medium temperature refrigeration settings. R404A is known for having a high GWP score, meaning the gas traps a lot of heat in the atmosphere which affects the environment through greenhouse gases (GHGs), so the aim is to move away from equipment that requires R404A gas. 

By working with the team at 7Eleven, we upgraded a number of their units to allow us to use a refrigerant that has a much lower GWP output.  

R448A is a newer refrigerant available which has a GWP output that is a third of the standard R404A output.  While machinery upgrades like this are not mandated, it is through insightful investment of companies such as 7Eleven, where selecting to reduce their global warming output, champions their dedication to their environmental policies.

When conducting these types of upgrades, Chatfield OzCool uses equipment such as the Copeland ZX Condensing unit for refrigeration applications, as this type of equipment allows greater efficiencies and is designed to run on the lower impact R488A gas. 

Similarly, the Kirby Guardian Evaporators are also designed to run on gases with low GWP refrigerants including R407F, R450A, R448A, R449A & R513A.

When you pair this equipment with the electronic TX valve that controls the refrigerant flow to ensure equipment is operating at optimal output, but with greater energy efficiency, you are building a system that has a multipronged approach to environmental benefits. 

The team at Chatfield OzCool are available to assist with cooling and refrigeration equipment service and repairs, and we are happy to answer any questions you may have.
