Values shown in the graph for a thermo-chiller without inverter are found by
calculation based on an assumption that a thermo-chiller is operated with a general refrigerant circuit that controls the compressor by turning
the power ON/OFF, and with a bypass to the circulating fluid circuit.

Space saving
Reduced wiring/labor
Keeping the size similar to the
(HRSH series) single chiller, the
temperature of 2 fluid channel
systems are controlled
individually.
One power supply system for
temperature control of 2 channels
Less work-hour for wiring
Circulating fluid can be heated without a heater.
