High Efficiency
High Efficiency

Rotating heat exchangers provide very high sensible and latent efficiencies.

Minimal Cross Contamination
Minimal Cross Contamination

Seals and purge sectors minimize the cross-contamination of exhaust air into the supply air.

Low Freezing Risk
Low Freezing Risk

Rotary heat exchangers offer very low freezing risk as the wheels by definition defrost themselves.

ROTARY FEATURES

All Heatex rotary heat exchangers share these features:

  • Heatex high-efficiency heat transfer matrix
  • Wheel diameters are available in 1 mm (0.039″) increments
  • Numerous well-heights from 1.4 to 2.5 mm (0.55″ – 0.98″)
  • Non-standard casing dimensions

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

rotary heat exchanger and its features

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)

rottary heatexchanger sealing
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.

rotor matrix
Molecular Sieve

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

lower part of rotary heat exchanger
Hatches & Cable Glands

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

electronic plastic enclosure
Modbus & Rotation Detector

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

power twist 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.
