Blue Star has made significant progress towards minimizing and even eliminating the environmental hazards resulting from CFCs in certain refrigerants used for cooling. As a matter of fact, Blue Star is one of the few companies selected in India for funding by "The Multilateral Fund for the implementation of the MONTREAL PROTOCOL". Blue Star has already introduced 'ozone friendly' centrifugal chillers using HCFC-123, the safe refrigerant replacing CFC-11. Blue Star also markets absorption chillers which use water as refrigerant. All Blue Star reciprocating chillers already use HCFC-22 refrigerant which is more friendly to the environment than the older R-12. The Company actively promotes wider use of large refrigeration systems using ammonia as the refrigerant. In fact, Blue Star is a member of the International Institute of Ammonia Refrigeration, USA.
