Introduction Fast facts
  • Double cross-counterflow plate heat exchanger where supply and extract air stay on the same level throughout the AHU.

    • Direct heat exchange without intermediate medium
    • Recovered energy can be controlled through a bypass
    • Long service life & easy and flexible in use

    • Air flow:  25 000 m³/h
    • Yield: Approx. 80% according to EN308
    • Integration in: CAIRplus, COM4top, CAIRpool, CAIRfricostar
    • The bypass valves must be equipped with a modulating actuator
    • The fresh air can be bypassed (freecooling and frost protection). For ECOTWIN the extract air is also bypassed (energy savings)
    • The fresh air bypass is necessary for applications with extract air with a relative humidity of >45%, at low outdoor temperatures and high efficiencies
    • No humidity recovery
    • Static exchanger, no moving parts (except for the bypass valves)
    • If there is no demand for heat recovery and in freecooling mode, the air side pressure drop across the recuperator and along the supply and extraction side almost equals 0 (energy savings)
    • Category I according to EN308
