HCR188C is a recently patented tried and proven hydrocarbon refrigerant. It is formulated from naturally occurring substances and is a non-toxic, non-ozone depleting replacement for most CFC refrigerants. HCR188C is intended as a natural drop-in replacement for R12 and R134 in existing systems without the need for component or oil change. It can be used in R22 systems with slight modification.
This environmentally friendly hydrocarbon refrigerant is inexpensive and economical to use. Its efficiency as a refrigerant has been astounding under test. Retrofitting and running costs are low.
All hydrocarbons are flammable but HCR188C requires such small quantities, (approximately 4-6 oz in a vehicle air conditioning system and approximately 1/2 - 1 oz in a domestic refrigerator), that it renders any risk assessment miniscule when the refrigerant is appropriately handled and normal HVAC safety measures are applied.
A retro safety valve was designed for use with HCR188C, for automobiles, but can be used with a split unit air conditioner. The valve is spring loaded and has the EPA assigned fitting sizes that have been approved by the EPA. The function of the valve is to shut off the refrigerant flow when the pressure drops below a certain level. When activated the remaining refrigerant in the system cannot leak into the passenger compartment of an automobile or into a building of a split unit air conditioner.Valves are placed close to the firewall on automobiles and before air conditioning lines enter a building.
