Customizable Water Cooled Screw Chiller with Low Noise and Durable Compressors for Various Cooling Requirements(30HP-60HP)
Can be customized acid-proof, anti-corrosion, frequency conversion, explosion-proof. Selected imported brand-name semi-hermetic screw compressors and semi-hermetic reciprocating compressors. Good performance and low noise. According to customer needs and the size of the cold tonnage, a single machine or a combination of multiple machines is used. The compressor can automatically alternate operation according to load changes, balance the operating hours of each compressor, and greatly extend the service life of the chiller.
Features:
compressor:
Selected imported brand-name semi-hermetic screw compressors and semi-hermetic reciprocating compressors.
Good performance and low noise.
According to customer needs and the size of the cold tonnage, a single machine or a combination of multiple machines is used.
The compressor can automatically alternate operation according to load changes, balance the operating hours of each compressor, and greatly extend the service life of the chiller.
Evaporator:
The copper tube of the evaporator adopts internal and external threaded reinforced tube. The surface of the copper pipe is threaded, the outer surface of the copper pipe is smooth, and the cooling effect is good. The evaporator body is insulated with a 25mm thick PE insulation board, which does not condense and reduces the loss of cooling capacity.
Condenser:
The condenser is made of copper pipes imported from foreign countries and processed into trapezoidal low help pipes to enhance the heat transfer capacity. The surface of the copper pipe is smooth, which reduces the water pressure and is easy to clean and maintain.
protective device:
The protection system devices include: temperature control switch, antifreeze switch, fusible bolt, high and low pressure switch, overload protector, compressor overheat protector, compressor frequent start protector and abnormal indicator light.
Computer control system:
The company has developed a high-intelligence PIC, PC-level computer control system, which can be used for remote monitoring and control, and is simple to operate. The host is connected to the power supply.
The failure rate is low, the safety factor is high, and the installation is simple. System control can be adjusted instantly, intuitive and reliable.
In commercial buildings like offices, malls, and hotels, maintaining optimal indoor temperatures is crucial for occupant comfort. Our water-cooled screw chiller utilizes a high-efficiency screw compressor and a water-cooled condenser to transfer heat from indoor spaces to an external water loop. This system cools large volumes of air by circulating chilled water through coils, providing consistent and energy-efficient cooling. With variable load control, it adapts to fluctuating occupancy, reducing energy consumption during low-demand periods.
