Features

Digital Compressor Control for an Additional 65% in Energy Savings Patented

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 RS-232C or RS-422 interfaces.

Applications

The following page shows application examples of the our Digi-Eco Chillers. Have a look!

Specifications

*1 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.
*2 The source voltage phase unbalance 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.
*5 The flow rate and head value noted for the discharge pump represent a power value at one point. Pump characteristics will differ between different models. For specific model details, please refer to the pump characteristic curves.
*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: 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 2: Please install the included strainer (40 mesh) to the fluid intake port.
Note 3: Heat output from the product (in kW) is approx. 1.3 times that of its cooling capacity. (Air cooled only)
