Features
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.Patented
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
The adjustable liquid temperature control range is 15 to 30℃.
External communications interface included as standard equipment.
Allows temperature control via RS-232C or RS-422 interfaces. (RKE22000A-VW only)

- Operation when liquid temp is 20 ℃, ambient temp is 32 ℃, and cooling water temp is 32 ℃. Cooling capacity is at least 95% of listed figures.
- The source voltage phase balance should be within ±3%.
- The figure noted is when the product is operating at its maximum rated capacity.
- Stable load indicates continued operation with maximum load fluctuations of ±10% of the current load. (Excluding cases where the electronic capacity control valve cycles ON and OFF.)Settings can be changed through parameter setting F15. (Default setting: High precision.)
- Operating noise levels are from a position of 1 m in front of the product and at a height of 1 m.
- Comes standard with a built-in multi-purpose earth leakage breaker for overload and short circuit protection.
- Please install the included strainer (40 mesh) to the fluid 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.
- The above two models are built-to-order items.
