Refrigerant

General Characteristics Environmental friendliness : OS-12b, a hydrocarbon blend refrigerant has been proven to be an environmentally safe refrigerant with zero ozone depletion potential(ODP)and near zero global warming potential(GWP) Drop-in replacement : OS-12b 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, autoclave test and compatibility 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-12b is fully compatible with a mineral oil of ISO viscosity grade 22 or 32 which is readily available from any local vendor. Economic benefit in operation and maintenance : The mass flow rate of OS-12b in refrigeration equipment is lower than that of CFC-12 and the amount of charge is reduced by 50% as compared to CFC-12 and HFC-134a. High Energy Efficiency : OS-12b provides 3.0% higher COP than CFC-12.
