Double skin Return air handling units with 4-8 rows cooling coil air flow 2,000-400,000 m3h

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.
