Water-cooled screw chiller (single unit)

Product features:

  • International top brand semi-closed 5:6 asymmetric twin-screw compressor, with international famous brand refrigeration valve.
  • The 4-stage energy adjustment mode can realize the maximum control of 25%-50%-75%-100 four-stage automatic control.
  • High efficiency external thread copper tube shell and tube heat exchanger. Ensure that the chiller is not affected by the ambient temperature.
  • International famous brand "Schneider" Electric, imported programmable controller and LCD touch screen, Chinese and English man-machine interface.
  • Multiple protection devices. Ensure the stable operation of the unit throughout the year.
  • Ultra-wide freezing water temperature variable range to meet different user requirements.
  • The use of ethylene glycol as a cold carrier can make the frozen water temperature as low as -30 degrees Celsius.

    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.
