RKL Unit Cooler (Air Cooled)
RKL-2200-D / RKL-3750-D /
RKL-5500-D / RKL-7500-D
- Cooling Capacity
(50/60Hz) - 7.9/8.5 to 25.0/27.1 kW
- Operable Ambient Temperature Range
- 5 to 43
- Operating Temperature Range
- 5 to 30
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.
Space saving design is perfect for space conscious layouts.
Slim vertical design. The unit can be placed with the back side against the wall.
Wide-Ranging Liquid Temperature Setting
Wide temperature setting range of 5 to 30 ℃. Original, easy-to-set temperature controller.

- Cooling capacity is at least 95% of listed figures.
- When liquid temperature is 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.
- Values indicated are at: 200V at 50/60Hz, 220V at 60Hz.
- The recommended liquid (chilled water) that can be used is either clean water or a 30 - 40% industrial-use ethylene glycol solution. Alternatively, if deionized water is used, it should have an electrical conductivity of at least 1µS/cm.
- Heat output of the equipment (in kW) is approx. 1.3 times the cooling capacity.
