HEAT-RECOVERY UNITS FOR SMALL VOLUMES OF AIR | 0.05–1.5 m³/s
We manufacture a variety of vertical and horizontal package units equipped with a counter-flow or rotary heat exchangers.
Our AHU’s are designed for commercial premises, like schools, day-care centres, offices, and industrial buildings where the air exhange places more challenges and requires larger output than in a private accommodation does.
Kesair’s factory-tested heat-recovery units are prefabricated with electrification and automation. Inbuilt birect-drive frequency-converter-controlled fans are easy to adjust and energy-efficiant.
Operating is easy via control panels on the devices. Alternatively, AHU’s can be delivered as terminal strip units and linked easily to a central control and monitoring system in the destination. We also deliver assemblys without any electrical and regulation equipment.
