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.

Advantages

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.
