What can I use to replace R22?

It depends on the type of system, as to which refrigerant is best for the application.  
 

We can make recommendations for specific applications depending on the circumstances.  However, ISCEON MO99 (R438A) can be used in most Dx refrigeration, air conditioning and chiller applications to replace R22.  We always recommend the conversion guidelines are consulted and followed.
