Refrigerant Types

F Gases

All the heat recovery systems promoted by DK Heat Recovery are design for use with F gases. Switching your gas charge away from R22 is a good time to install a heat recovery system as you will save on installation cost. Alternatively whilst your contractor is effecting the switch get him to install shut offs and add break-in points for later installation of heat recovery systems. They will be all the rage soon!


One of the leading manufacturers of heat recovery has developed a system that can cope with the pressures involved with CO2 system which is already deployed in Germany. We seek our first UK installation for this technology.


Ammonia’s corrosive affect rules out the use of copper based heat exchangers. DK Heat Recovery Limited can refer you to providers of technology for recovering heat from ammonia based systems.
