Inverter Direct-Drive Centrifugal Chiller

Description

NES first developed inverter direct-drive centrifugal chiller with the patented horizontally back-to-back compression technology with crossover pipe structure. Balance the thrust forces for longer life span and improved efficiency by less seal leakage and no gear loss. COP up to 6.55, IPLV up to 10.70

Two-stage compressing

6% higher efficiency than single-stage compression. Lower speed and higher reliability. Unique three-stage separation economizer, reliable and effective.

Zero in-rush current

The unit adopts inverter starting mode, which produces no in-rush current during the starting process and enables a stable operation from OA to FLA.

Horizontally back-to-back compression technology

Midea first developed the patented horizontally back-toback compression technology with crossover pipe structure. Balance the thrust forces for longer life span and improved efficiency by less seal leakage and no gear loss.
