Temp Control Precision
  • Compressor Inverter Control
    Orion chillers respond to work loads using the least amount of energy.
  • Discharge Pump Built-In
    Built-in discharge pump supplies water to your equipment (in a closed loop configuration).
  • External Signal Terminals
    Terminals are provided for an operation signal, warning signal, and remote operation.
  • IPX4 Equiv. Rating
    Outdoor installation is possible.Installation in direct sunlight, strong wind (8 m/sec or higher), or contact with falling snow, or freezing conditions require further measures.
    IPX4 is a class rating connected with water ingress, and indicates that no harm will come to the product should it come into contact with rain or water splash from any direction at a rate up to around 10 L/min.
  • HFC Refrigerant: R-407C
  • Remote Control Unit (Optional)
    A remote control unit (available as optional equipment) offers all of the control features found on the chiller's main operation panel.


Achieves up to 57%* Energy Saving Control

Orion chillers respond to work loads using the least amount of energy.
* Compared to hot bypass systems at 30% load.

High precision liquid temperature possible using ORION's original technology.

The chiller senses the liquid temperature and adjusts the compressor speed accordingly, thus achieving liquid temperature precision control of ±0.2 to ±1.0 ℃.
* May fluctuate due to load conditions. Therefore, please consult with us if the higher level of precision is required.

Wide Ranging Liquid Temp Control Possible

User settings of liquid temperatures from 5 to 35 ℃ are possible.

External communications interface included as standard equipment.

Allows temperature control via RS-232C or RS-422 interfaces.


See the following page for application examples using our heavy duty AC inverter chillers.

Specifications Chart

*1 Operation when liquid temperature is 20 ℃, ambient temp. is 32 ℃. Cooling capacity is at least 95% of listed figures.
*2 The source voltage phase balance should be within ±3%.
*3 The figure noted is when the product is operating at its maximum rated capacity.
*4 Stable load indicates continued operation with maximum load fluctuations of ±10% of the current load. (Not including times when the load is in the range of 25 to 40%.) The setting can be changed through parameter setting F15.(Default setting: High precision.)
*5 Please operate with a head of 50 m or less.
*6 Operating noise levels are from a position of 1 m in front of the product and at a height of 1 m.
*7 Comes standard with a built-in multi-purpose overload and short circuit protection earth leakage breaker.
Note 1: Please install the included strainer (40 mesh) to the liquid intake port.
Note 2: The recommended liquid (chilled water) for use in this product is clean water or a 30% to 40% solution of industrial-use ethylene glycol. Note that there will be a drop in cooling capacity of 10 % if using a 30 to 40 % ethylene glycol solution. Alternatively, if conditioned water is used, then it should have an electrical conductivity of at least 1 µS/cm.
Heat output from the product (in kW) is approx. 1.3 times that of its cooling capacity.
Note 3: The above models are built-to-order items.

External Dimensions (Units: mm)

*1: Put the signal lines and communication cables for respective wirings through the holes separate from the power cord hole.
