Front Access

Space Saving

Caster Adjuster-foot Kit (Optional accessory)

Applicable for installation in locations other than 19-inch racks. This is a set of unfixed casters and adjuster feet stop.

Temperature stability: ±0.1ºC

A precision temperature control method which utilizes expansion valves and temperature sensors allowed for the realization of a product with a high temperature stability of ±0.1°C.

Self-diagnosis function and alarm code display

Display of 28 types of alarm codes Operation is monitored at all times by the integrated sensor.
The applicable alarm code (28 types) is displayed after self-diagnosis.

Menu for maintenance schedule

When it is time for periodical checks of the pumps, fan motor, dustproof filter, etc.,
a maintenance code will be generated as a reminder. Helpful for facility maintenance

Displaying screen for operating conditions

Thermo-chiller internal temperature, pressure, etc., can be displayed.

With heating function

As the heating method uses discharged heat, a heater is unnecessary.
The heating function is effective in maintaining a constant temperature, particularly in the winter when the ambient temperature is low.

Communication functions

Serial communication (RS-232C/RS-485) and contact input/output signals (2 inputs and 3 outputs)
are equipped as standard. This allows for communication with the user’s equipment and system construction, depending on the application.

Inverter specification mechanical sealless pump HRR010 to 030 Option T1, HRR050-□-40

Power supply (24 VDC) available
