KRYZ -40°C ~ +100°C Temperature, Flow, and Pressure Control System Chiller-LNEYA

CHILLER Temperature, Flow, and Pressure Control System

Adopting a variable frequency vortex compressor, the operating speed is automatically adjusted according to actual needs, providing the required cooling capacity. Compared with traditional fixed frequency compressors, it significantly reduces energy consumption and improves energy efficiency performance.

Constant power output function for both hot and cold.
