Introduction for refrigerant R600a

Characteristics

High purity of more than 99.9% - Increase a durability of the system
10% increase in energy efficiency compared with HFC134a
Alternative for HFC134a
No need to change compressor, heat exchangers (evaporator & condenser), and oil
45 ~ 50% reductions in charge compared with HFC134a
Equivalent discharge temperature compared with HFC134a
Azeotrope with small temperature glide - No change of the composition when leak the refrigerant
No ODP, very low GWP compared with HFC134a (environmentally friendly products)
Use the mineral oil (it is very cheap)
