ACVATIX TM PTC conductive heating element ASR70 Accessory to extend the application range on modulating refrigerant valves, MVS661.. and MVL661..
Use The PTC conductive heating element ASR70 is used as an accessory on modulating refrigerant valves: ● MVS661… ● MVL661… ASR70 extends the application range of valves for refrigerant temperatures at the valve inlet below 0° C. Typical applications include pump systems with ammonia or CO2 refrigerant machines. The heating element must be under power as long as the refrigerant temperature at the valve inlet is below 0° C and is below the valve’s ambient temperature.
