stable operation

Refrigeration compressor adopts imported brand-name fully enclosed compressor, with low noise and high efficiency. Equipped with high-efficiency heat exchange copper tube, imported refrigeration valve parts and famous brand parts, the cold water machine is durable and stable in operation.

Easy to operate

The daily operation of the industrial chiller is concentrated on the body control panel, and the operation is clear at a glance. Imported microcomputer digital temperature controller, set freely, precise control, can provide 5~20 ℃ frozen water.

Efficient and flexible

Air-cooled industrial chillers do not need to configure auxiliary cooling towers and pumps; water-cooled industrial chillers are not affected by ambient temperature and can continue to provide stable frozen water. The bottom of the small equipment is equipped with a movable angle wheel, which can adjust the position of the equipment at will, and is equipped with multiple sets of frozen water interfaces, which is flexible and convenient.

Safe operation

In addition to the protection device of the refrigeration compressor itself, the industrial chiller is also equipped with an air switch, thermal overload protection, refrigeration high and low pressure protection, power phase sequence protection, water tank water shortage protection, delay control function and automatic reset operation function to ensure the safe operation of the chiller.
