Features
Digital Compressor Control for an Additional 65% in Energy Savings
Thanks to our original digital control (LOAD/UNLOAD) technology, we have achieved high-efficiency energy savings across the full range of loads from 0% to 100%.
Safe and Reliable Design
The RKED Series inherits its primary functionality from ORION chillers which have been receiving high marks from our customers. And thanks to simplified structural components, we've achieved a highly reliable chiller suitable in a wide variety of applications.
External communications interface included as standard equipment.
Allows temperature control via RS232C or RS422 interfaces.

- When operating under these conditions: chilled water temperature is 20℃, ambient temperature is 32℃, cooling water temperature is 32℃. Cooling capacity is at least 95% of listed figures.
- Source voltage phase unbalance should be less than ±3%.
- The figure noted is when the equipment is operating at the hirhest capacity of its normal operating range.
- Stable load indicates continued operation with maximum load fluctuations of ±10% of the current load.
- The capacity figures listed represent just one point on this model's flow-rate / head characteristic curve. Pumps differ between model's; for model specifif details, please refer to the pump characteristic curves.
- Operating noise levels are from a position of 1 m in front of the product and at a height of 1m in front of the unit and at a height of 1m.
- Unit comes with a built-in multi-purpose overload and short circuit protection breaker.
- The recommended liquid (chilled water) that can be used is either clean water or a 30% to 40% industrial-use ethylene glycol solution. Alternatively, if deionized water is used, it should have an electrical conductivity of at least 1µS/cm.
- Please install the included strainer (40 mesh) to the liquid intake port.
- Heat output of the equipment (in kW) is about 1.3 times the cooling capacity.
