Patented High-Efficiency Compressor from Germany

Semi-hermetic double-screw compressor that adopts R134a is used.

Three-stage oil separator with efficiency up to 99.5%.

Efficient motor with large capacity can significantly increase the EER.

High-Efficiency Heat Exchanger

Efficient flooded-type shell-and-tube heat exchanger, super-efficient heat exchange tube, inner-threaded tube, and external fins substantially increase the heat exchange efficiency.

V-type heat exchanger is adopted at the air side, with dual-module seamless configuration.

New open-window aluminium fin greatly enhances the air turbulence and increases the heat exchanging efficiency by about 8%.

Unit Microcomputer Control Center

Advanced pre-control function enables measures to be taken promptly before actual failure occurs to avoid frequent startup/shutdown.

Full-lifecycle cloud-based data management system provides comprehensive control and powerful big data support for customers.

Unique Smart Defrosting Technology

Smart defrosting: Based on temperature parameters measured by the sensor, the unit can precisely determine the existence of frost by analyzing the unit operating parameters.

Minimum defrosting duration: Under national defrosting conditions, the defrosting duration is only 4.5% of the total heating duration.

Defrosting EXV control: The EXV can precisely control the opening during defrosting to avoid problems of traditional thermal expansion valve such as liquid hammer and oil shortage.
