SMC HRSH090-WN-20 Water Cooled Thermo Chiller Unit

Module Feature

HRSH090-WN-20 belongs to SMC HRSH090 series inverter-type thermo chiller. W stands for water-cooled structure, N is configuration option, 20 stands for 200V power specification. It adopts variable frequency compressor control, stable cooling capacity output, temperature control precision up to ±0.1℃ under stable load. The wetted parts support deionized water, ethylene glycol aqueous solution and other cooling media. Built-in flow, pressure and temperature multi-point monitoring, with multiple safety interlock protection. Compact cabinet layout, low noise operation. Widely used for laser processing equipment, CNC spindle cooling, semiconductor process equipment and laboratory analytical instruments.

Working principle

The refrigeration circuit uses inverter compressor to adjust cooling power dynamically according to the set temperature. The heat of the circulating fluid is transferred to the refrigerant through plate heat exchanger. The cooling water from factory water system takes away the condensation heat of refrigerant. PID controller adjusts compressor frequency in real time to keep the outlet fluid temperature stable within the target range. Internal circulating pump drives cooling liquid to circulate to the load side.

Onboard components

Inverter compressor, plate heat exchanger, circulating pump, expansion valve, pressure sensor, temperature sensor, PID touch controller, flow switch, safety relief valve, internal piping and filter assembly.

LED indicators

Touch screen display with LED alarm lamp, shows running status, temperature, flow and fault alarm information.

Hardware self‑diagnosis

Self-diagnosis covers high/low refrigerant pressure, flow shortage, over-temperature, pump overload, cooling water abnormality and sensor failure. Fault codes are stored and displayed on the panel.

Programming software

Local touch screen edits temperature setpoint and alarm parameters; supporting SMC monitoring software for remote status reading and data logging.
