R-E-EX
Enthalpy rotary heat exchangers, recover both sensible heat and moisture between exhaust and supply air. A rotating aluminum matrix with a hygroscopic coating pre-conditions outdoor air, which lowers heating/cooling/humidification loads and improves indoor comfort. R-E-EX units are optimized for balanced ventilation where humidity control matters.

Principle of operations
A coated rotor alternately passes through the warm, humid exhaust and the cooler, drier supply stream. It absorbs heat and water vapor from the exhaust, then releases them to the supply air on the next half-turn - without mixing the air streams.
Rotor matrix
High-quality aluminium foil with a hygroscopic 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 centres, 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.
