Rotors for air conditioning technology
The highest form of thermal energy recovery in air handling systems is the rotary heat exchanger.
There is no other system of energy recovery that can deliver high efficiencies with high air volumes in limited room spaces.
As an innovative market leader with over 30 years experience with numerous aplication possibilities and the manufacture of rotors, we possess the widest range of different types and versions available.
Function principle
The rotor which is constructed like a honeycomb, rotates non-stop between the stream of hot exhaust air and the cold intake air.
The rotor is warmed up in the stream of exhaust air and transfers the heat to the stream of incoming cold air.
Up to 80% of the heat and humidity contained in the exhaust air can be recovered in this way.
Housing types
With many different housing types it is possible to offer you a large bandwidth of transfer mediums encompassing many characteristics such as different geometries for sensible, sensible / latent energy recovery, applications in aggressive or corrosive atmospheres matching your requirements and operating conditions.
For every place and every application, the right rotary!
The housing are optionally galvanized steel, aluminum, aluminum-zinc or stainless steel including mounted motor systems and options for inspection either frontal or from the side. All dimensions of the housing are adaptable in steps of 1 mm (0.04 in). If desired we can produce special housings with an integrated bypass.
Storage mass
Condensation rotor for sensible energy respectively heat recovery: latent only in condensation state P/PT
The Condensations rotor for sensible energy respectively warm energy recovery (P/PT) will be applied only in units without humidifying and without cooling.
Energy recovery: only sensible, latent only in case of condensation
Enthalpy rotor for sensible and latent energy recovery through hygroscopic surface of the transfer medium.E/ET
For sensible and latent energy recovery through hygroscopic transfer medium (E/ET). Application for units with pre humidifying without cooling.
Energy Recovery: Sensible, latent limited.
Epoxy rotor for sensible energy respectively heat recovery; latent only in condensation state. (K/KT)
For sensible warmth and energy recovery. Latent only in case of condensation. (K/KT).
Epoxy coating for higher corrosion resistance.
Application in units with higher levels of return air loads. I.e.:
- Swimming baths
- Industry extraction
- Adiabatic return of humidity
- Paint booth rotors
Heat recovery: only sensible, latent only in case of condensation.
Sorptions rotor for sensible and latent energy respectively heat recovery over the whole year through a highly hygroscopic coating (HUgo)
For high sensible and latent heat and energy recovery all year round through a highly hygroscopic coating (HUgo).
Application in units with humidifying and cooling. Reduction of the cooling power consumption due to drying and cooling of the return air.
Heat recovery: sensible and latent the whole year round.
Sorptions rotor SECO is the benchmark in temperature and humidity transfer. The latent efficiency stays constantly in line with the level of sensible efficiency, independent of the inlet conditions in the rotor.
SECO rotors are used where constant drying in all areas of the climate and drying control industry is required.
- High sorptions respectively de-sorption capacities.
- Kills germs, therefore hygienically efficient.
- No odour transfer.
- Dehumidifying without air heater, especially by high
humidities.
Heat recovery
Rotor profiles
Material thickness:
- 0.12mm: Special rotors for paint booths for example.
- 0.10mm: For frequent high pressure cleaning and higher risks to the life expectancy.
- 0.08mm: standard: For A/C systems with moderate exhaust air pollution, suitable for high pressure cleaning.
- 0.07mm: For A/C systems with moderate exhaust air pollution.
Corugation height:
- 16: Higher efficiency through smaller tighter windings but a higher pressure loss.
- 19: Standard: A/C systems with moderate exhaust air pollution.
- 25: Special version for high levels of air pollution
Drive motor
Driving motor
The rotor drive is made possible through an a/c motor with a V - drive belt. The motor is mounted on a sprung rocker panel to ensure belt tension.
New direction in motor technology
Energy saving DC motors in compact form for our rotary heat exchangers. Direct motor activation without extra regulator. Our new innovations open possibilities to optimize the serial production of air conditioning systems.
Cleaning chamber
The cleaning chamber or purge section works as follows: A small part of the supply air stream is redirected into the exhaust stream thus ensuring the cleaning process. Equally, any migration of exhaust air into the supply stream is inhibited. The mode of operation can only be warranted when the correct pressure conditions are available. Most rotors are supplied without the cleaning section as the marginal contamination is acceptable.
Cleaning devices
For the regenerative heat exchangers there are several automatic cleaning devices with electric or pneumatic drive system and regulator Type AS1. They can be selected according to the degree of pollution received by the rotor.
Air cleaning
Air/ water cleaning
Double-sided air/ water cleaning

Apart from those shown here there are many more field of application available. The photographs here show , by the way, just a few of the projects where we have successfully installed rotary heat exchangers and other products.
Cooling of data centers with enormous savings of energy with rotary heat exchangers in special execution.
