THE PROMISE, THE PROOF

ROTARY HEAT EXCHANGERS

ROTARY HEAT EXCHANGERS

In a rotary heat exchanger, the heat from the exhaust air is picked up by the aluminum matrix and transferred to the supply air as the wheel turns.

Models

Heatex rotary heat exchangers provide very high sensible and latent efficiencies. Models with casing are fitted with seals for excellent airtightness and can be equipped with purge sectors to minimize the cross-contamination of exhaust air into the supply air. By adding coatings to the wheel, humidity transfer or increased corrosion protection is enhanced. We offer an extensive range of options regarding sizes, material, and drives to suit various applications and performance requirements. Select a model below for detailed information, suitable options and accessories.

Model E

Model E is a high-performing, compact and lightweight rotary heat exchanger.

Model E is a high-performing and lightweight rotary heat exchanger designed for air handling units, primarily for comfort ventilation applications. Typical temperature efficiencies are up to 90%.

Model E offers one of the most compact casing available on the market. This gives an exceptional efficiency compared to conventional rotary exchangers with the same casing dimensions. The casing is manufactured from galvanized steel and provides high torsional rigidity.

The airflows may be oriented as side by side or top/bottom, and the complete rotor may be installed in a vertical as well as in a horizontal orientation.

Air leakage between wheel and casing is minimized with a brush seal allowing easy adjustment, longer lifetime and low friction. The two air streams are also separated by adjustable brush sealants.

Model E’s performance is certified according to Eurovent, AHRI and TüvSüd. Model E also meets several hygiene requirements.

Only the wheel, without casing, is called Model O.

Model EN

Model EN is a high-performing small rotary heat exchanger without casing, designed to be fitted directly inside an air handling unit or mounted in a cassette.

Model EN is a high-performing small rotary heat exchanger without casing, designed to be fitted directly inside an air handling unit or mounted in a cassette, primarily for residential ventilation applications. Typical temperature efficiencies are between 75-80%, but with design optimization, the efficiency can approach 90%.

The product holds a smaller diameter hub and bearing which maximizes the airflow for small residential air handlers. Further, a glued aluminum wrapping allows for high output and durability.

Model EN is available in different widths, adding one more dimension for perfection in residential air handling design.

Model EN is certified according to Eurovent.
