Features
IR Impact
¥
Semi-Hermetic Reciprocating Compressors cover the whole application range
regardless of whether traditional or chlorine-free HFC refrigerants are used. The latest
innovation is the "C Series" which offer very compact size, universal application, minimum
energy consumption, and very low vibration levels.
All IR Impact
¥
compressors have the same robust valve plate construction, high quality wear
resistant drive parts, efficient suction gas cooling, built-in motors and proven oil-return system.
For low temperature R-22 applications I-Cool with switchable suction strainer and Inject-Cool
liquid injection systems are available.
Key features of IR Impact
