Product Details

Hydro Water Chiller

Hydro Water Chiller is a unit adopting the cooling tower cooling refrigerant circulatory system to exchange heat and then to get the air

conditioning and process chilled water. It works together with the terminal devices to complete the whole air conditioning system.

Test ability, technical level

1.GRAD has the National Laboratory of Air Conditioning Products recognized by CNAS, which is used for the design, development and experimental research of water-cooled chiller and the factory test of products.

2.Strict factory product quality control, so that users can buy at ease, with satisfaction.

3.GRAD screw type water cooled chiller series products ware tested by the national air conditioning quality testing center, the technical performance indicators are higher than GB/T184330.1-2007"Vapor compression cycle cold water (heat pump) unit Part 1: Industrial or commercial and similar uses of cold water (heat pump) units "standard, product quality is stable, reliable operation, has been praised by the majority of users at home and abroad.

Applications:

Comfort air conditioning systems: large supermarkets or commercial complexes, hotels, shopping malls, office buildings, exhibition halls, airports, stadiums, etc.

Process air conditioning systems: electronics, biology, light textile, chemical engineering, metallurgy, pharmaceuticals, power, machinery, etc.

Hydro Water Chiller

Components

1. Semihermetic screw refrigeration compressor, with simpler structure, even and continuous inlet and exhaust air, small running shock, high stability and long life span.

2. Shell & tube evaporator and condenser

3. Expansion valve: electronic expansion valve control system can meet as much as 2600 steps control precision, which can make the unit keep optimal condition.

4. All the assembly work will be finished in the factory and the unit can be delivered after qualified operation and trial test.

5. Microcomputer control system.
