R-N-EX
Sorption rotary heat exchangers recover sensible heat and moisture even at low relative humidity, where standard hygroscopic coatings lose effectiveness. A selective sorption layer pre-conditions outdoor air across wide climate ranges, lowering heating/cooling/humidification loads while keeping indoor RH stable. R-N-EX is ideal where humidity control is as critical as temperature.

Principle of operations
A coated aluminum rotor alternates between warm, humid exhaust and cooler, drier supply air. Its molecular-sieve sorbent (e.g., 3Å zeolite) adsorbs water vapor and heat in the exhaust stream, then desorbs them to the supply stream on the next half-turn - without air mixing - delivering high latent recovery down to low RH.
Rotor matrix
High-quality aluminum foil with a selective sorption coating for moisture transfer between streams.
Options:
- Foil thickness: 0.055 or 0.07 mm
- Wave height (corrugation): 1.4 / 1.6 / 1.8 / 2.1 mm
- Rotor width (depth): 100 or 200 mm
Casing and frame
- Galvanized steel - cost-effective for general use
- Aluminum - lightweight, corrosion-resistant; good for marine/humid sites
- Stainless steel (AISI 304/316) - for chemically aggressive or highly humid environments
Main areas of use
Applications
- Residential ventilation - apartments, multi-family houses.
- Commercial buildings - offices, shopping centers, schools, cultural spaces.
- Industrial facilities - workshops, warehouses, production halls.
- Hospitality & wellness - hotels, fitness clubs, swimming pools (humidity control with enthalpy/sorption rotors).
- Large public venues - airports, arenas, exhibition halls, transport hubs.
