Features

Our inverter controlled compressor responds to fluctuating workloads linearly, achieving highly accurate temperature control while using the least amount of energy. Plus, thanks to Orion's distinctive capacity control system, accurate temperature control can still be maintained during normally difficult to control low load situations. (User can choose between "High-accuracy" and "Energy saving" modes in response to low-load conditions.)

As much as 65% Energy Savings Possible		Temperature Control Accuracy to ±0.1 °C*
Even compared with power saving ON/OFF type chillers, our DC Inverter control models offer energy savings of 30 % at full load. And when compared with temperature-stable hot gas bypass or PID proportional valve controlled chillers, a 65 % reduction in energy requirements is possible.		Precise control even for applications that have severe temperature management requirements. Its extreme versatility makes it suitable for a wide range of applications, including precision-production-use lasers, analysis devices, semiconductor manufacturing, and many others. ※ Under stable load and ambient temperature.

*1 For operation on air-cooled machines when the chilled water temperature is 20 °C and the ambient temperature is 32 °C. Cooling capacity is at least 95% of listed figures.
*2 Power supply voltage phase imbalance shall be maintained to within ±3%.
*3 Max. electric current upon operating under the shown specification.
*4 Exclude cases such as, at start-up, whenever the cooling load is low, or whenever turning the compressor ON-OFF
*5 Operation noise shown is of frontward 1m , and a height of 1m.
*6 Overload protection combination circuit breaker is built-in as a standard feature.

Note 1) Recommended fluid (Cooling water) for the device is pure water, or industrial ethylene glycol solution with 30 - 40% concentration. Please use Aurora brine, or Nybrine Z-1 as the industrial ethylene glycol. Electrical conductivity shall be 1µS/cm or lower for the pure water. If you may wish to use the 30 - 40% lowly concentrated ethylene glycol solution, please be informed that the cooling capacity drops by approximately 10%.
Note 2) Equipment exhaust heat rate (kW) is approximately 1.3 times of the cooling capacity.
