Iran Sarma multipoint air purger is specially designed to maintain the efficiency
Refrigeration purgers
The Iran Sarma Purger is a simple, robust, high-capacity device that removes non condensable gases & water from the refrigerant vapor in a system. The unit operates by condensing foul gas (the mixture of refrigerant vapor and non-condensables) from one or more purge points, metering the purified liquid refrigerant back to the system through a protected suction connection, and venting the noncondensables to atmosphere.
Water contamination of the ammonia refrigerant is common in many refrigerating systems
