Model E

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 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.

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

Silica Gel or Molecular Sieve

Add coating like silica gel or molecular sieve to enable humidity transfer. Depending on the application you might want to add a condensate tray to collect and move water created by condensation out of the system.

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 + Modbus

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 Powerbelt is our toughest option. This belt is used without tensioning device and can be used at temperatures up to 110°C (230°F) and in humid climates. It’s easily joined together without any tools or locks.

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
