FOIL AND MEDIA
Condensation (Sensible), Non-Hygroscopic Rotors (OT, OC, OK)
The condensation rotor is a cost-efficient solution to recover heat and is suitable for standard applications in comfort ventilation. Humidity is only transferred in cases when the dew point of one of the air streams is reached.
Sorption Rotor (OM)
100% of the media in this rotor is coated with molecular sieve 3Å which provide a MAXIMUM of humidity transfer capacity for MINIMAL Carry Over. The high humidity efficiency is constant throughout all climate conditions. Sorption rotors are especially designed for summer season cooling recovery and dehumidification of outdoor air. Therewith, it should always be used in humid and hot climates, with dry cooling systems (chilled beams) and when in winter time humidifiers are used. This substantially reduces the cooling and humidification demand of the HVAC system. The OM rotor also provides an extended corrosion protection and is therefore also suitable for marine applications.
Hybrid Rotors (OH)
60% of the media in this rotor is coated with molecular sieve 3Å the remaining 40% is standard sensible media. The mix of sensible and Sorption rotor gives a HYBRID with extended support for humidity transfer. The OH have a performance slightly lower than OM, used for standard applications in comfort ventilation systems where extended need of humidity transfer is requested.
Increased Corrosion Protection (OC, OK)
In an environment with aggressive components in the air it is either recommended to use a rotor with epoxy coating (OC) or a sea water corrosion resistant foil (OK) for better corrosion protection. Such applications can be, e.g. dairy industry, on ships or for coastal areas. Other applications for additional corrosion protection are adiabatic cooling and cooling rotors of Direct Evaporative Cooling (DEC) units.
