Features

① Optimized Design

International standards are fully utilized by anti-modular system design ensure high reliability, large temperature difference and small flow technical idea is able to minimize cost, water consumption and reduce expenses for running.

② Excellent Performance

The main body is equipped with globally advanced semi-hermetic screw compressor, integrating the motor, without worrying about shaft seal leakage. Multiple refrigerating circuits provide flexibility for part-load operation.

③ Wide Scope of Application

Scope of water source temperature applicable for the unit:-8~35°C. The air conditioner cold hot water as well as 50°C hot water can be provided in summer. High temperature unit can provide as high as 60°C hot water.

④ Complete Safety Protection

Pressure protection: High and low pressure protecting devices. Motor protection: Voltage-loss protection, phase-loss protection, inverse phase protection and over-heat protection.
