Model E Rotary Air-to-Air Heat Exchanger

PRODUCT INFORMATION

Overview

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 galvanized steel casings available on the market. This gives an exceptional efficiency compared to conventional rotary exchangers with the same casing dimensions.

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.

OPTIONS

We offer a wide range of options to suit various application and performance requirements.

Corrosion Protection

Epoxy and Painted Framework

Increase corrosion resistance with a painted framework combined with an epoxy coated wheel and corrosion-resistant ball bearings.

Cross Contamination

Purge Sector and Special Seal

Models with casing can be equipped with special seals and a purge sector to minimize the cross-contamination of exhaust air into the supply air.

Humidity Transfer

Matrix Material

Depending on the application you might want to enable humidity transfer and add coating like silica gel or molecular sieve.

Fit and Accessibility

Covered Casing, Hatches, Cable Glands

The covered casing automatically comes with inspection hatches and cable glands which also are selectable separately.

Drive Equipment

Advanced Step Drive & Control

Heatex Model E comes with an advanced step drive & control with Modbus as standard but other types of drives are also available.

Drive belt

Powerbelt

The power belt is used without a tensioning device and our toughest option due to high wear resistance. Also suited for hot and humid climates.

High Efficiency

All Heatex rotary heat exchangers share the same high-efficiency matrix and a wide variety of well-heights to suit various performance requirements.

All units are produced at our global production facilities with our proprietary production equipment according to the same standardized processes, ensuring uniform product quality and favorable lead times worldwide.

Conformity

Heatex air-to-air heat exchangers are designed to comply with all national and local building codes.
