Save On ElectricityImmediately
We are the developers and manufacturers of environmentally friendly blended energy saving natural refrigerants.
In other words, we simply supply a blended natural refrigerant gas for inside your existing air-conditioner.
Refrigerants are the working fluids used in all air-conditioning and refrigeration systems worldwide.
We Have The Solution!
Engas Pty Ltd supplies specially blended, energy saving Hydrocarbon Refrigerants which are natural refrigerants that have no ozone depleting properties and absolutely minimal global warming potential.
With governments worldwide phasing down Hydrofluorocarbon, (HFC) chemical refrigerants under the Montreal Protocol's Kigali Amendment, the shift to low-GWP alternatives is not optional — it is law. Launched in 2010, backed by over 16 years of engineering and product development, Engas hydrocarbon refrigerants are the internationally patented, future-proof solution.
We manufacture and distribute our blends throughout the world!
The Montreal Protocol
Adopted September 16, 1987
What is it?
The Montreal Protocol is a landmark international treaty aimed at protecting the ozone layer by phasing out the production of ozone-depleting substances (ODS). It was established to address the depletion caused by man-made chemicals, particularly chlorofluorocarbons (CFCs) and halons — commonly used in refrigeration, air conditioning, and aerosol propellants.
Why it matters
The Montreal Protocol is considered one of the most successful environmental agreements in history. It has been ratified by every country in the United Nations, making it the first treaty to achieve universal ratification. Thanks to the Protocol, the ozone layer is on track to recover to pre-1980 levels by mid-century.
The 2016 Kigali Amendment extended the Protocol to phase down hydrofluorocarbons (HFCs) — powerful greenhouse gases used as replacements for ODS. Engas hydrocarbon refrigerants, with a Global Warming Potential of less than 1, are the future-proof solution aligned with this global commitment.
Why Engas?
CSIRO-Verified Savings
Up to 36.5% less electrical input power and 32.5% higher energy efficiency. Independently verified by CSIRO.
Future Proof
With Hydrofluorocarbon, (HFC) phase-downs now law. Engas natural refrigerants with Global Warming Potential (GWP) of less than 1 will never face regulatory obsolescence.
Hot Weather Performance
Engas's M60 blend has a critical temperature of 90°C which means there is No performance drop in extreme heat, unlike R410a (71.3°C) and R32 (78.1°C).
Pure Quality
Engas has internationally patented blends delivering up to 435 kJ/kg refrigerant effect — nearly 4 times the capacity of R410a.
CSIRO-verified to save up to 36.5% on energy consumption. As Hydrofluorocarbon (HFC) refrigerants face government-mandated phase-down, our natural hydrocarbon solutions deliver lower costs, zero ozone impact, and a future-proof path for your cooling systems.
Engas Verification Units — Power Savings Comparison
See the Electricity Savings in Action
Engas verification units showing the electricity saving comparison of R410a and Engas M60 Hydrocarbon Refrigerant. The video demonstrates the energy savings when using the M60 Engas compared to the man-made chemical refrigerant R410a. The conversion is called a Retro-fit and once completed there will be between 25-40% electricity savings for the life of the air conditioning unit.

What Our Customers Say
Hear from businesses and individuals who have made the switch to natural refrigerants.
"Subsequent use of the air-conditioning in the following weeks has seen vent temperatures down as low as 7.9 degrees, while the outside temperature is in the 30's. This is a cooling level that has never been achieved before, and most remarkably a very hot Porsche engine does not seem to have the same detrimental effect that it used to have."
