 Product Description

With over 15 years of experience in designing, producing, selling, and installing central air conditioners, Ruidong has become a trusted Chinese company. We always supplying Water Cooled Scroll Chiller to World markets. These high-performance chillers incorporate top-quality components including scroll compressors, water-cooled condensers, evaporator heat exchangers, water pumps, water tanks, refrigeration circuits, cooling towers, control panels, vibration isolators, and protective devices. Ideal for commercial and industrial cooling needs, Ruidong's Water Cooled Scroll Chillers are renowned for their efficiency and reliability.

Water Cooled Scroll Chiller has a wide list of applications as: Change over thermal storage, heat pumps cooling, commercial applications as hypermarkets, supermarkets, low-temperature brine cooling, process cooling, building layouts, etc.


Features

1. Water chiller scroll compressor is included in the 7-280kw model. Each compressor is equipped with both a crankcase heater and a thermal overload cut-out for improved safety and performance.

2. The water chiller system is equipped with external rotor type axial fans. These fans feature three phase direct drive motors, operate at a low noise level, have 8 poles, and are protected by an IP54 rating. Additionally, they are provided with a protective outlet grille for added safety.


The evaporator is built with a high efficiency shell and tube type heat exchanger. It comes factory insulated with flexible close cell material to enhance energy efficiency and prevent heat loss.

3. Condenser consists of seamless copper tubes that are mechanically expanded into blue hydrophilic aluminum fins. This construction facilitates efficient heat transfer and corrosion resistance.

4. Refrigerant circuit is complete with various components including charge valves, a filter drier, a sight glass, a gas-liquid separator, and a thermostatic expansion valve. The heat pump unit also includes a 4-way valve, liquid receiver, and a one way valve for effective operation.

5. Hydraulic circuit is built using galvanized pipe and includes a water discharge connection for the shell and tube heat exchanger. Flange type hydraulic connectors ensure secure and reliable connections.

6. Electric panel includes essential components such as a compressor contactor, fan motor contactor, compressor isolating switch, fan protection breaker, phase sequence relay, and a microprocessor with function display. These features contribute to the unit's automatic operation and decreased maintenance costs.

7. The reliable microprocessor system enables automatic operation, thereby reducing maintenance costs significantly.

Safety system:

1. Compressor reverse protective

2. Freeze protector protective

3. Refrigerant safety valve

4. Buzzer

5. High-pressure gauge and Low-pressure gauge

6. Power phase failure protector

7. Coil over-heat protector

8. Temperature auto-switch

9. Refrigerant shortage protective
