50 mm PU insulation double skin modular fresh air handling units with heat recovery wheel 

EKDM air flow range is from 1000m3/h to 400000m3/h. Available functional sections include fresh/return air mixing section, cooling section, heating section, primary/medium/high efficiency filter section, electric heating section, humidifying section, sound attenuation section, heat recovery section, secondary air-return section, fan section, air diffuser section etc. Different combinations can meet different air handling requirements.

•   The surface  of the unit is made of quality color steel, which can resist corrosion, scratch and ultraviolet radiation.

•    Internal panels are made of steel plates galvanized  with aluminum and zinc, with an assured  service life of more than 15 years. All panels  feature  end-to-end  joints and smooth surfaces, without any bur or corroded point.

•    The internal panels feature reinforced design, which is strong enough to support the largest  air handling unit.

•    The unit panel  has two thicknesses,  namely  30mm and 50mm.Inside  the panel, hermetically foamed polyurethane (no fluorine) with a density of 48kg/m3 is used as the heat- insulating material. The heat conductivity factor is less than 0.02W/m°C.

•    Each functional section of the unit is equipped  with a steel trough base, thus  ensuring  it is well supported,  easy to transport and assemble. The overall robustness of the unit meets the  standard of CEN2.

Heat Recovery Section

The wheel heat recovery is molded using customized alveolate metal template and coated with special desiccant adsorbing material. In typical installations, the wheel is fixed in the middle of the pipe and divided into two half-moons, pumping stagnant indoor air out of one half-moon, and fresh air into the other. Meanwhile, the wheel revolves slowly (approximately 20RPM) to transfer sensible/latent heat from one half-moon to the other through its metal plates and desiccant absorbing material (heat liberation), condensing vapor from high-humidity side and releasing vapor into low-humidity side by evaporation and heat absorption.
