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

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.

The adjustable liquid temperature control range is 15 to 30℃.

Allows temperature control via RS-232C or RS-422 interfaces. (RKE22000A-VW only)

See the following page for application examples using heavy duty AC inverter chillers. Have a look!

*1 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.
*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. (Excluding cases where the electronic capacity control valve cycles ON and OFF.) Settings can be changed through parameter setting F15.(Default setting: High precision.)
*5 Operating noise levels are from a position of 1 m in front of the product and at a height of 1 m.
*6 Comes standard with a built-in multi-purpose earth leakage breaker for overload and short circuit protection.
Note 1: 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.
Note 3: The above two models are built-to-order items.

*1 Signal and communications related wiring should not pass through the same hole as power cables.
