Special Features
By combining two technologies, energy saving and high temperature control accuracy, ORION offers both.
Temperature stability

Small < Operating Cost > Large
The compressor is controlled by an inverter, saving energy and controlling the temperature accurately. With Orion’s special technology, the control is stable and precise continuously. (The user can choose between “High Precision Mode” and “Energy Saving Mode” in case of low working load.)
Save energy up to 65%
Compared with chillers controlled by on/off compressor system,
our DC inverter chillers
can save 30% energy in 100% operation.
And compared with chillers controlled by thermal bypass or PID system,
our DC inverter chillers can save 65% energy.
Accuracy level ±0.1℃* from actual use results
With strict temperature control, it can support various high-precision work, such as high-precision laser work, conductive parts manufacturing machinery, multi-step continuous processing machinery, etc.

*1 Chilled water level 20℃ and outside temperature 32℃ Chilled water temperature is achieved when operating at 95% of capacity.
*2 Try to control the electric current so that it does not fluctuate beyond the specified value of ±3%.
*3 Maximum current from full-rate operation.
*4 Except when turned on/off by pressure system, it may cause a load on the unit.
*5 Measure the sound level at a distance of 1m in front of the unit and 1m above the unit.
*6 Install a circuit breaker to prevent electric leakage.
Warning 1) This chiller uses ethyl alcohol with a concentration of 30-40%, including pure brine (Aurora Brine) for Z-1.
Or, pure water of 1µS/cm must be used as a conductor. If ethyl alcohol with a concentration lower than 30-40% is used, the cooling efficiency will decrease by approximately 10%. Warning 2) The heat generated (kW) is approximately 1.3 times the cooling power produced.
