Features The rooftop heating and cooling unit does not need a specialized room for installation. New air vents can be set up as fresh air volume can be manually adjusted and the pre-filter section can also be configured according to the client's requirements.
Easy assembly. The machine set adopts air cooling and direct air supply methods. Cooling towers and circulating water systems are not necessary. The rooftop packaged heating and cooling unit can be easily installed on rooftops, balconies and other suitable places. The machine set can immediately start working by just connecting the air return pipe and power onsite.
High air quality. The heating and cooling unit has air supply, refrigeration, heat supply, air purifying and electronic control functions.
Reliable operation. Overload protection and open-phase protection devices are built in the heating and cooling unit to guarantee the safety and reliability of use.
