PROPERTIES OF REFRIGERANT - 410A
- R410A is an an azeotropic mixture of HFC-32 & HFC-125
- Chlorine - An element that is damaging to the ozone layer
- R410A contains No Chlorine
- R410A comes in rose coloured cylinders
- R410A has higher cooling capacities & pressure
- At 77 degrees Fahrenheit its density is 50% greater than that of R-22 & its vapor pressure is 58% greater
- Low toxic
- It is non-flammable
- Used for Unitary A/C ( Central A/C ), Chiller & Commercial RAC
- Compressor Lubricant type - Polyolester based
- R410A chemically compatible - they will not reach or form other compounds if accidentally mixed
- R410A is a high vapor pressure gas- Attention to design pressure rating of handling, storage,recovery and storage cylinders
- R410A W.P = 400 psi
- DOT( Department of Transportation) recovery cylinder rated for 400 psi or higher to be used for recovering 410A
- R410A expands when heated
