Product Features

Optimised design

It is designed in full compliance with international standards and combined with China's actual national conditions. The design of the system adopts independent modularisation idea with high reliability. The technical idea of large temperature difference and small flow rate saves the user's precious water resources and reduces the operation cost.

The system is designed with the idea of independent modularity, which is highly reliable. Computer-aided optimal control ensures that the unit is in the best operating condition under any working conditions.

◆ Superior performance

The host adopts the international advanced semi-closed screw compressor, motor, compressor integration, no shaft seal leakage concerns.

Single compressor or more than one compressor with start-up, shutdown round-robin control procedures, balanced load of various components, prolonging life.

Single compressor or more units with multiple refrigeration circuits, one of the circuits to be serviced, the rest of the circuit can still operate normally, with mutual standby function.

The compressor adopts unloading and voltage reduction to start, avoiding the impact on the power grid.

◆ Wide range of applications

The unit is applicable to a wide range of water source temperature: 8-35℃. It can provide both hot and cold water of 7℃ or 45℃ for air-conditioning and 50℃ for domestic hot water. In addition, the high-temperature type unit can provide hot water of up to 60℃.

It can be used directly in the original radiator heating system or as a heat source for urban district heating.

◆ Full range of safety and protection features

Pressure protection: high pressure protection and low pressure protection device.

Motor protection: loss of voltage protection, phase shortage protection, reverse phase protection, motor overheating protection.

Anti-freezing protection: when the temperature of chilled water is too low, the unit stops.

Safety valve protection: when the refrigerant pressure exceeds a certain value, the safety exhaust valve will open automatically.

Various protections of the above equipment make the unit run safely and stably.
