The storage mass consists of coiled layers of corrugated and smooth corrosion-resistant aluminium foil; the smooth layer boasts a highly effective sorption coating for humidity transmission. The surface coating made up of a 3 Å molecular sieve acts as a sorption medium for ideal humidity transmission. The result is small, axially arranged, smooth ducts for laminar flow of air. The outside of the storage mass is supported by the rotor mantle; the hub is inside with the permanently lubricated, maintenance-free roller bearings and the axle. The rotor is permanently stabilised by internal spokes between the rotor mantle and hub.
- Sheet-steel casing (for one-piece rotors)
Self-supporting construction of Aluzinc sheet steel, suitable for installation in ventilation units. There are adjustable seals around the rotor periphery and along the centre beam. The standard casing models are intended for vertical installation; however, smaller models can be ordered for horizontal installation.
- Profile casing (for multi-component rotors)
Construction of aluminium extruded sections with Aluzinc sheet-steel panels, suitable for installation in ventilation units. There are adjustable seals around the rotor periphery and along the centre beam.
- Drive motor
The drive motor is installed inside the casing. It drives the rotor via a pulley and a rotating V-belt. The gear ratio is measured in such a way that the rotor reaches the optimum speed.
- Constant drive
Rotary heat exchangers with a constant drive work in on/off mode; the speed of the rotor is not controlled.
- Variable drive
The variable drive system is made up of a motor with an associated control unit. The control units and motors coordinate perfectly with one another.
- Casing width in 1 mm increments; max. ∅ + 1000 mm
- Casing height in 1 mm increments; max. ∅ + 1000 mm / max. height: ≤ 2550 mm
- Triangular inspection hatch: the triangular inspection hatch makes it possible to inspect the inside of the HVAC unit from the supply-air side and extract-air side. (∅ ≥ 1000 mm)
