Temp. control accuracy

Refrigeration operation in all temperature ranges/cooling of heat-generating loads at high temperatures (up to +80°C)

It is possible to cool the heat load at high temperatures, which was not possible with conventional products

A compact water tank is used to reduce the amount of circulating liquid, making it economical.

The pipes are all stainless steel and can be used with pure water (A1 level). Nybrine is recommended for use at temperatures below 10°C

Various support functions such as auto stop, auto start and calibration offset functions features as standard. The system also includes functions to monitor energy consumption and CO2 emissions.

Data can be sent and received by RS-485 with the external communication function.

CLS302・CLH302/401/610 CLH401/610

■ CLS302 Low temperature type with an operating temperature range of -10°C to room temperature and a temperature control accuracy of ±1.5 to 2.0°C (refrigerator ON-OFF control)

■ CLH302/401/610 Wide range and precision temperature control with an accuracy of ±0.1°C for use from -10°C (-15°C) to 80°C (refrigerator+heater control).

The flow rate of the circulation pump can be set freely by using a flow adjustment valve.

The flow sensor detects the low flow rate of the piping system, turns on the alarm lamp to stop operation and protect the device.

Quick auto stop, auto stop, auto start operation, and Various functions such as calibration offset function, temperature output terminal, RS485 external communication function, etc. It is equipped as standard.

Safety features Self-diagnostic function, overcurrent leak breaker, key lock function, power failure compensation function, low-flow monitoring, etc. refrigeration monitoring, refrigeration operation indicator, delay timer function for refrigeration protection, flow rate error, high pressure error, etc.
