Air-handling units for large volumes of air

LARGE HEAT-RECOVERY UNITS for air volumes between 0.2–10 m³/s

Kesair’s large heat-recovery units are designed for an air-flow range of 0.2–10 m³/s. The units are equipped with a cross-flow heat exchanger, rotary heat exchanger or with glycol-circulation heat recovery. The units can be adapted and customised in accordance with customer needs, and delivered in several parts. A wide range of different acessories make it possible to meet your specific needs.
