SEMI Standard Chiller

HRZ recirculating chillers are especially suited for high technology sectors, by conforming to several SEMI equipment standards and regulating fluid temperature to ±0.1°C.  Inverters control the rotations of both the pump and compressor for energy efficiency.  Refrigerants include R454C (EU and US compliant beyond 2025), and CO2.  HRZ chillers can circulate various coolants including fluorinated types (Fluorinert™ and GALDEN®), ethylene glycol and water.
