Panasonic Low-Temp Hermetic Unit 8-12.5HP Top Discharge (Economized Vapor Injection)
【Economized Vapor Injection (EVI) Technology】
Economized vapor injection increases cooling capacity and COP at low evap temps by 15-20%.
【Panasonic Dedicated EVI Compressor】
Panasonic compressors with intermediate suction port for vapor injection cycle.
【Economizer + Electronic Expansion Valve】
Plate heat exchanger economizer + electronic expansion valve for precise injection control.
【Suited to Demanding Low-Temp Applications】
Ideal for blast freezers, ultra-low temp storage, and high-efficiency cold chains.
