Non-standard casing dimensions

Depending on the application, you might need a certain rotary model, including options.

CHOOSE YOUR MODEL

Every Model has a clear advantage, depending on your application needs.

Heatex Model	E & O	EQ & EV	EN
Description	E has one of the most compact casings on the market. Each wheell size has an optimized casing size.	EQ and EV facilitate on-site installation or in narrow spaces. It also provides for lower transportation costs due to its segmented design.	EN holds a smaller diameter hub and bearing, which maximizes the airflow for small residential air handlers.
Airflow capacity	200 – 90 000 Nm³/h (125 – 56 000 CFM)	2 000 – 190 000 Nm³/h (1 170 – 110 000 CFM)	50 – 2000 Nm³/h (30 – 1 177 CFM)
Rotor design	One piece	Segmented	One piece
Configuration	With casing (Model E) Without casing (Model O)	With casing (Model E) Without casing (Model EV)	Without casing
Exchanger orientation	Vertical Horizontal	Vertical only	Vertical Horizontal
Rotor diameter	500 – 2575 mm (19.69″- 101.38″) +50 mm (1.97″) with casing	1600 – 4000 mm (47.24″ – 157.48″)*	200 – 500 mm (7.87″ -19.7 “)
Additional features	Slide-in solution, no attachments in AHU needed (large casings only) Wheel tilt function for minimizing leakage and wear (large casings only) Diagonal motor placement for easy access (large casings only) Covered casing (optional)	Adjustable shaft in all directions Insulated casing (optional)	Smaller dimension hub and bearing for maximized airflow Glued aluminum wrapping for high output and durability

OPTIONS

We offer a wide range of options to suit various applications.

gray and gold colored rotor heat exchanger

Corrosion Protection

Epoxy & Corrosion Protected Framework

Increase corrosion resistance with a corrosion-protected framework, epoxy-coated wheel, and corrosion-resistant ball bearings.

Leakage Reduction

Purge Sector & Sealings

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

Molecular Sieve

Depending on the application, you might want to enable humidity transfer and add a coating like molecular sieve.

Fit & Accessibility

Hatches & Cable Glands

Inspection hatches and cable glands allow for easy access to the motor, belt, and pully for quick inspection and maintenance.

Drive Equipment

Modbus & Rotation Detector

Depending on the model, we offer constant or step drives with Modbus and a built-in rotation detector.

Drive Belts

Power Belt

The Power belt can be used without a tensioning device and is our strongest belt, suited for hot and humid climates.

FAQ & DOCUMENTS

How does a rotary heat exchanger work?

The wheel is built up by a matrix that consists of two foils, one flat and one corrugated; together, they create channels for the air to pass through. The wheel is rotated by an electric motor and belt drive system.

In one half of the rotation, the exhaust air from the inside space flows through the matrix. Its heat is stored in the matrix, and in the other half of the rotation, it is transferred to the fresh supply air from outside.

The size of the channel is called well height. Different well heights and diameters of the wheel give different efficiencies, pressure drops, and airflow rates.

Rotary heat exchangers that are properly constructed, installed, and maintained have almost zero transfer of particle-bound pollutants.
