Why is Oz-Chill different?
Oz-Chill requires that its products are made within strict specification. In fact, the refrigerant product is made of only the Most Pure, Quality, Refined ingredients available today. Oz-Chill Refrigerant is computer blended within ¼ of 1% and certified by an ISO 9002 major American petrochemical supplier. Manufactured and Bottled in the United Sates. Australian Owned!
Are Oz-Chill Refrigerants corrosive to air conditioning systems?
No! Oz-Chill Refrigerants are non-corrosive, and do not form acids in combination with system moisture.
What is the difference between Oz-Chill Refrigerant and HFC-134a or R-12?
Oz-Chill Refrigerants are an all-natural, non-ozone depleting material with 0 Ozone Depleting Potential and just 3 Global Warming Potential. Oz-Chill Refrigerant is organic and has NO impurities. In fact, it is so pure, it is classifies as a pharmaceutical grade product! R-12 and HFC-134a are man-made, chemical refrigerants that do not utilize all natural products. R-12 has both, high global warming and high ozone deletion, while HFC-134a does not effect the ozone, it does have a very high global warming potential according to reports.
How do I know how much refrigerant I need in my vehicle?
Usually you will find this information on the label by the engine, inside one of the doors, in the vehicles manual, or contact your dealer for this information.
Can I lower “head pressure” in my air conditioning system by using Oz-Chill Refrigerant?
Yes! Oz-Chill Refrigerants can extend equipment and component life by lowering compressor “head pressure” up to 33%. In most cases, Oz-Chill Refrigerants are capable of delivering energy savings and will result in a considerable reduction in operating costs!
The system converted to Oz-Chill will also generally sound a lot quieter and smoother.
What are Oz-Chill Refrigerant’s?
Oz-Chill Refrigerant’s are a proprietary blended ultra high efficient hydrocarbon refrigerant direct replacement for many types of Chemical Refrigerants such as HFC-134a and R-12 Substitutes.
They are Manufactured from the purist Naturally Occurring, Non-Toxic Hydrocarbons. They are then blended to create 3 different Refrigerants that are used for different applications; these are 12a, 22a and 502a.
Are Oz-Chill Refrigerant’s flammable?
Oz-Chill Refrigerants are flammable to an open flame or spark and is rated as a Flammable Gas 2. This means there is a moderate chance of fire or flame. However, flammable products are used every day within the household, business and in automobiles. Just think about sitting in a Taxi with a 90litre tank behind you or under you. Or even a Barbecue, where your actually trying to burn the gas for cooking!!!!
Aerosol products such as hairspray, room deodorizers, under arm deodorant, penetrating oil, WD 40, etc are all classed as a flammable and are used all over Australia and the world as a safe product in home and automotive used when used as per manufacture directions. Hairspray = Flammable 3, Gasoline = Flammable 4, Starting Fluid = Flammable 4, Oz-Chill Refrigerant = Flammable 2. Oz-Chill Refrigerant can be used safely in automobiles just like other flammable automotive products required in vehicle operation. All flammable products require your respect, adequate precaution and safe use practices. Follow all directions on the can or label.
Is Oz-Chill Refrigerant compatible with all refrigerant oils?
Oz-Chill refrigerants are fully compatible with most common refrigeration lubricants. All Oz-Chill refrigerants are soluble with all refrigeration oils. It can be used with Mineral, Ester and PAG oils without incompatibility. Oz-Chill refrigerants should not be used with silicone oils.

Is Oz-Chill Refrigerant approved by the USEPA?
Oz-Chill Refrigerant does not fall under or within the guidelines set forth by Congress concerning global warming or ozone depletion because it is an environmentally safe, non-global warming and non-ozone depleting product.
According to the US EPA website, under the SNAP rule, the EPA regulates/reviews substitutes for CFC R12. Direct replacements for CFC R12 are called “first generation” substitutes. HFC 134a is a replacement for R12 because it does not threaten the ozone layer and, therefore, it is a “first generation” replacement. Oz-Chill Refrigerant is considered a “second generation” substitute for HFC 134a and other CFC R12 substitutes.
Therefore, Oz-Chill Refrigerant does not require “approval” to be used or sold as a HFC 134a or other CFC R12 substitute.
Does Oz-Chill offer technical assistance?
Oz-Chil offers Technical Assistance at 1300 83 50 30 during regular business hours which are M-F 8am-5pm WST and will provide after hour emergency numbers at your request.
We also have pressure charts and other useful information available on this website or call us at 1300 83 50 30 for further assistance.
Are Oz-Chill Refrigerants energy efficient compared to other refrigerants on the market today?
Yes! Oz-Chill Refrigerants are up to 50% more efficient than Hydrofluorocarbon (R12 and R134a) refrigerants. This efficiency means only approximately 1/3rd of the original amount of Oz-Chill refrigerant in a system is needed to replace the same chemical refrigerant.

Molecular Size
The smaller the size of refrigerant molecules in a confined space, the larger is the surface area of the combined molecules.
As noted in the table above, the molecular size of the Hydrocarbon is only 41.1. while R22 is 86.5 and R410a is 72.6! This is less than half of that of R22 and is thus twice the surface area in a confined space relative to R22 refrigerant.
When measuring the performance of refrigerants, the larger the surface area, the more heat will be dissipated. Hydrocarbon refrigerant is therefore able to reject heat much faster at any point in time from the air-conditioning systems relative to R22 and R410a refrigerants.
Refrigerant Efficiency
How fast a refrigerant is able to transfer heat at any point in time is measured in joules per gram.
The test hydrocarbon refrigerant is able to transfer heat at the rate of 367 joules per gram and is regarded as one of the most efficient natural refrigerant in the market today.
In comparison, R22 refrigerant is only able transfer heat at the rate of 163 joules per gram.
Hydrocarbon is therefore 125% more efficient as a refrigerant relative to R22 and R410a.
The combination of the molecular size, refrigerant efficiency and lower head pressures due to the hydrocarbon refrigerant, all help contribute to reduced wear and tear on each system. This could save thousands of dollars in maintenance costs and will increase the standard operating life of the compressor and other parts.
Does Oz-Chill Refrigerant contain an odor?
Yes, it contains a “fresh pine scent” which is added during the bottling process. The “fresh pine scent” was designed to assist consumers in leak detection. The “fresh pine scent” immediately notifies the operator and others within the vehicle of a leak within the air conditioning system.
Is Oz-Chill Refrigerant environmentally safe?
Absolutely! Oz-Chill Refrigerants are organic, non-ozone depleting, non-toxic compounds. These type of refrigerants are endorsed by the GreenPeace and United Nations Environmental Program (www.refrigerantsnaturally.com) and are in full compliance with the UN Montreal Protocol.
What seals are compatible with Oz-Chill Refrigerants?
Most all common elastomer and plastic refrigeration materials used as o-rings, seals, and gaskets are compatible with Oz-Chill refrigerants. Butyl hoses are incompatible and should not be used with hydrocarbon refrigerants.

Will Oz-Chill help you reduce your Carbon Footprint?
Yes, it sure will! Not only will you save substantial amounts of money on running costs, but you will also be dramatically reducing your Carbon Footprint. Converting to the naturally occurring refrigerant (Hydrocarbons) you will rid the world from enormous amounts of Carbon being emitted into the atmosphere. The Chemical refrigerants R134a, R22 and R410a all have extremely high GWP (Global Warming Potentials) of 1,300 to over 2,000. While Hydrocarbons only have a GWP of just 3! Some of these chemical refrigerants are now being phased out globally and hopefully they will all be gone one day.
So why continue using a Chemical Refrigerant from a Chemical Manufacturer, when the world already supplies us with Naturally Occurring Hydrocarbons?
Hydrocarbons are the way of the future…
How does Oz-Chill compare Environmentally?
The below graph shows the classification, ODP, GWP and Atmospheric Life of 4 of the most commonly used Chemical Refrigerants and Oz-Chill 22a.
Why are Oz-Chill Hydrocarbon Refrigerants to efficient?

Molecular Size

When measuring the performance of refrigerants, the larger the surface area, the more heat will be dissipated. Hydrocarbon refrigerant is therefore able to reject heat much faster at any point in time from the air-conditioning systems relative to R22 and R410a refrigerants.
