80HP screw chiller unit, various models are available.
Cooling capacity up to 260KW.
The electric control system of the screw freezer adopts highly intelligent PLC and PC-level microcomputer control system. Responsive, precise control.
Shell-and-tube condenser and evaporator: The condenser of the screw refrigerator uses different types of heat-exchanging copper tubes, and the outer surface of the copper tubes is processed into a trapezoidal low-finned tube to increase the heat exchange area and enhance heat exchange performance.
The inner surface of the copper pipe is smooth, which reduces the water pressure and is easy to clean and maintain.
Six Protections.
The power of the screw chiller is relatively higher than that of the scroll chiller, and it is mainly used in large-scale industrial refrigeration such as central air conditioning systems, chemicals, textiles, food, pharmaceuticals, and chemical fibers.
The thermal expansion valve, solenoid valve, check valve and other control components of international famous brands are selected to ensure the efficient and stable operation of the unit in a wide range of operating conditions.
