Features

Outstanding energy saving effect with the triple inverter!

The inverter respectively controls the number of motor rotations of the compressor, fan and pump according to the load of the user’s application.
Power consumption reduced by 34% compared with a thermo-chiller without the inverter.

With the inverter, it is possible to operate with the same performance even with the power supply of 50 Hz.

Flow diagram

Cooling capacity 10 kW, 15 kW, 20 kW, 25 kW

Max. ambient temperature 45°C

Low-noise design Operating noise Max. 68 dB

Circulating fluid pressure adjustable

Temperature stability ±0.1° C (when a load is stable)

By controlling the DC inverter compressor, DC inverter fan, and electronic expansion valve simultaneously, it maintains the good temperature stability when the heat load fluctuates.

Circulating fluid can be heated without a heater.

Heating method using discharged heat makes a heater unnecessary.

Reduces the maintenance hours for the pump

Mechanical seal-less immersion pump is used.

As the pump has no external leakage of the circulating fluid, a periodic check of the pump leakage and replacement of the mechanical seal are not necessary. There is no need to exhaust the circulating fluid when removing the pump.

Compact and lightweight 280 kg (HRSH250-A-20)

With caster adjuster-foot
(Option)

Electric conductivity control set
(With DI filter + Solenoid valve kit for control)

Set control range: 5.0 to 45.0 μS/cm

The electric conductivity of the circulating fluid can be set with the controller monitor arbitrarily.

Outdoor installation,
　Spashproof type (IPX4)

IP (International Protection) is the industrial standard for "Degrees of protection provided by outer defensive enclosures of electric equipment (IP Code)" according to IEC 60529 and JIS C 0920.

IPX4: No harmful influence by water splash is acceptable from every direction.

Globally compatible power supplies

(Europe, Asia, Oceania, Central and South America)

Power supply: Applicable to 200 to 230 VAC, or 380 to 415 VAC

Transformers are unnecessary even when used overseas.

Improved maintenance performance

Power supply (24 VDC) available

Power can be supplied from the terminal block on the rear side to external switches etc.

Communication function

The serial communication (RS232C/RS485) and contact I/Os (2 inputs and 3 outputs) are equipped as standard. Communication with the user’s application and system construction are possible, depending on the application. A 24 VDC output can be also provided, and is available for a flow switch (SMC’s PF3W, etc.).
