 Product Description

Ruidong water cooled screw chiller and pump is designed with a modular structure, where each module has identical dimensions except for its length. This modular design allows for flexibility in meeting different cooling and heating requirements. The modules are interconnected through an advanced communication system that is controlled by a micro-computer, ensuring optimal efficiency in operation. With the ability to combine different modules, the chiller and pump system can adapt to a wide range of cooling and heating demands.

The use of an Air Cooled Screw Chiller offers several benefits. These include its robust performance, stability, dependability, noiseless operation, effortless installation, long-lasting durability, and advanced multiple control systems. An Air Cooled Screw Chiller has contained the following major components:

Screw Compressor

Air Cooled Screw Chiller is composed of semi-hermetic double screw compressors that the controller can handle to modulate the capacity. A screw compressor is a rotatory compressor with one or two screws. It is highly efficient and continually compresses air by its screw action. It converts refrigerant vapors from low temperature and pressure to high temperature and pressure vapors. It then transfers the highly pressurized vapors into a tube condenser.

Evaporator

Located between the compressor and expansion valve, the evaporator is where gas exchange occurs. The low-pressure liquid refrigerant absorbs heat from warmer water passing through the evaporator, converting it into vapors while lowering the water temperature.

Condenser

The condenser is constructed using aluminum fins and copper tubes. It condenses the high-pressure and warm refrigerant vapors into a liquid, reducing the temperature and enhancing the refrigeration effect.

Expansion Valve

The expansion valve functions to decrease the liquid refrigerant’s pressure and lower the temperature of the liquid. The refrigerant gets colder under reduced pressure and move towards the evaporator.

Cooling fan

An Air Cooled Screw Chiller includes a cooling fan that extracts heat from the system and dissipates it into the atmosphere. A high-quality cooling fan improves the overall efficiency of the chiller installation.

Environmentally Friendly

The operation of an Air Cooled Screw Chiller does not have any adverse effect on the environment. Since it uses R407c/R413a refrigerant that is eco-friendly and harmless to the ozone layer.

Easy Operation

It comes with a modern control system, a microcomputer programmable controller (PLC), and a screen display, which allows you to control the operation easily as per your requirements.
