Product Details

Liquid cooling equipment is suitable for semiconductor testing, electronic equipment constant temperature testing, cooling server supporting infrastructure, and other fluid temperature control places.


  • The heating method within 40 ℃ is heated by compressor hot air.
  • The circulation system adopts a fully closed design, and the circulation pump adopts a magnetic drive pump.
  • 100% helium detection, 100% safety inspection to ensure the safety
    and reliability of the system.
  • 100% continuous operation of copy machine after 24 hours.
  • Condenser Micro-channel heat exchanger (air-cooled), plate heat exchanger (water-cooled)
  • Evaporator: plate heat exchanger
  • Throttling device: electronic expansion valve
  • Control system: PLC programmable controller
  • Communication: RS485 interface Modbus RTU protocol, Ethernet interface TCP/IP protocol
  • Operation interface: Wuxi Guanya customized 7-inch color touch screen, temperature curve display\EXCEL data export
  • Circulation system: The whole system is a fully closed system, low temperature does not absorb moisture in the air, does not volatilize heat transfer medium, low temperature automatically replenishes heat transfer medium into the circulation system.
  • Shell material: cold-rolled plate spray RAL7035
  • The inside of the pipeline contains: stainless steel SUS304, copper, ceramics, silicon carbide, silicone sealant, PTFE.
