MECHANICAL Electrical Instrumentation & Control Chemical Engineering Service & Maintenance HVAC(Heating, Ventilation, and Air Conditioning) Cubicle Cooler Product Description: HI AIR KOREA (HAK) has developed various types of customizable CCs (Cubicle Cooler) in response to the highly demanding room air requirements for use in nuclear power plants. HAK CC is composed of a filter, fan, and cooling coil in a compact casing. When used with other HAK air conditioning equipment, this CC serves as a useful device to complete a high-quality air conditioning system. The air conditioning system in nuclear power plants can be completed in the best way with HAK's reliable CC.
