COOLING
ROOFTOP UNIT
HI AIR KOREA(HAK) ROOFTOP UNIT is designed to withstand and operate optimally in some of harsh conditions in industrial plants, and it is generally installed on the rooftop. This is also called SINGLE PACKAGED AIR CONDITIONING UNIT because it is combination of AIR HANDLING UNIT and AIR COOLED CONDENSING UNIT.
HAK ROOFTOP UNIT is a cost-effective unit that can comply with stringent requirements of global standards. All of our units are designed considering optimized size, high efficiency, reliability, and maintainability.
HAK Industry plant ROOFTOP UNIT is specifically constructed to operate in various applications such as thermal power plant, refinery and petro-chemical plant, etc.
The ROOFTOP UNIT is generally required to be built using sturdy and good-valued materials so as to prolong the lifetime and be preserved. The unit has developed in close cooperation with major customers, so it can meet demanding requirements.
The Most Customizable Unit for Every Application!
