RKS Unit Cooler (Air Cooled / Water Cooled)

Features

Built with a heat exchanging coil that inhibits clogging and can be disassembled when required.

Chillers that use external water tanks are susceptible to foreign substances entering the system. With Orion's distinctive heat exchange coil system, there is less likelihood of clogging and yet, in the unlikely chance that clogging does occur, the coil can be removed for cleaning.

Connections and controls are focused onto the front panel for improved ease of use.

Our improved layout has operating switches, temperature display, IN/OUT water piping, and drain port, all accessible on the front panel.

Works well in space saving, low profile environments.

The height of the chiller has been lowered as much as possible allowing convenient placement in most site layouts.

Cooling capacity is at least 95% of listed figures.
When liquid temperature 20℃ and ambient temperature is 32℃.
Fan motor static pressure is 20Pa.
Operating noise levels are from a position of 1m in front of the unit and at a height of 1m.
At 200V 50/60Hz or 220V 60Hz.

The recommended liquid (chilled water) that can be used is either clean water or a 30-40% industrial-use ethylene glycol solution. Aiternatively, if deionized water is used, it should have an electrical conductivity of at least 1µS/cm.
Heat output the equipment (in kW) is about 1.3 times the cooling capacity. (air cooled models only)
RKS750F-W is a built to order item.
