Hydrocarbon Gas

With the introduction of the Synthetic Greenhouse Gas Legislation customers have been enquiring into the use  of the hydrocarbon gas, as its price will not be affected by the legislation. 

As Travel Cool was one of the first businesses in WA to supply the  Hydrocarbon gas, we are familiar with its application, and provide all the necessary equipment and relevant information. The product we supply is OS-12a and comes from the Superchill range.

Please refer to our products page for all orders.

What is the Natural Organic Refrigerant OS-12a?

OS-12a is a blend of purified R600a and R290, these are two natural hyrdrocarbon refrigerant gases. The blend of OS-12a has been specifically designed for the Automotive, Transport, Mining and Agriculture airconditioning systems as a complete drop in replacement for CFC-12 and HFC-134a.  



OS-12a's initial boiling point of -34 degrees celcius offers maximum cooling in  

high ambient applications.  

Environmental friendliness

OS-12a, a hydrocarbon blend refrigerant has been proven to be an environmentally safe refrigerant with zero ozone depletion potential (ODP=0) and near zero global warming potential (GWP=3 ) compared to that of HFC-134a that has zero ozone depletion potential (ODP=0) but with a high global warming potential (GWP-1300)

Drop-in replacement

OS-12a offers a similar volumetric capacity as CFC-12 enabling the use of CFC-12 compressors without any change due to similar thermodynamic properties as those of CFC-12.

Compatibility with mineral lubricant

After thousand hours of heavy load test, autocalve test with several lubricants in domestic refrigerators and test rigs, no problem was found in all parts of a compressor and no degradation of mineral oil was shown. Also OS-12a is fully compatible witha mineral oil of IO viscosity grade 22 or 32 which is available from any local vendor. OS12-a is also compatible with PAG and PAO automotive oils.  


Compatible with all automotive air conditioning systems such as compressors, condensers, evaporators, pipes and seals

Economic benefit in operation and maintenance

The mass flow rate of OS-12a in refrigeration equipment is lower than that of CFC-12 and the amount of charge is reduced by 65% as compared to CFC-12 and HFC-134a.

High Energy Efficiency

OS-12a provides 3.5% higher COP than CFC-12.

Safety evaluation of flammable refrigerants

The probability of fire or explosion caused by a leakage of ignited hydrocarbon refrigerant that could cause harm is presumed to be 3 out of 10 million cars in a year. The probability of a car accident that is caused by fire in the passenger compartment is presumed to be 1 in 10 million cars in a year. Whether the leakage of refrigerant is naturally caused or by a car accident the leakage would be in the engine bay where heat would evaporate the refrigerant before ignition. In comparing  OS-12aand HFC-134a, HFC-134a will also burn if ignited under pressure and will produce a toxic gas


The warranty on the Super Chill range of refrigerants is for a twelve month period from the date of installation of the product. OS-12a with its combination of excellent lubricant carrying properties and the lower operating pressures ensure long compressor life and plenty of cold air from the vents.
