    Humidifying (AHU) air handling units with backward fan high ESP

     

     

    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.

     

     

    Humidifying section

     

    The relative humidity of the air changes as areas and seasons change. Different operating conditions have different requirements on humidity. In dry areas and seasons, or in environment that requires high humidity, you may need to install a humidifier. Standard humidifiers for EKDM series units use dry steam. In addition, EK also provides high-pressure spray, wet film humidifying, electrode humidifying etc. If you have any special requirements on humidifying, please contact EK.

     

    Humidifier Introduction

     

    High-pressure spray humidifier—equal-enthalpy humidifying; water distribution pipes and nozzles made from stainless steel; high pressure spray; efficient, safe, reliable and energy saving. 

     

    Wet film humidifier— saturation efficiency; space-saving; reducing total length of the unit; no water handling; safe and reliable. 

     

    Dry steam humidifier—equal-temperature humidifying; high humidifying efficiency; made from stainless steel; graceful exterior; and corrosion proof. 

     

    Electrode humidifier—high humidifying efficiency; multiple control solutions to choose from. 

     

    Electric heating humidifier——efficient and accurate.

    Wet film humidifier

     

    Wet film humidifier humidifies the air through natural water evaporation. Its paper-like medium is made of macromolecule inorganic material which is highly hydrophilic. When dry air passes through the medium, water in the medium takes up heat in the air and evaporates to humidify the air. Wet film humidifier can use domestic water or tap water, and has the following advantages:

     

    ■ Clean humidification—no “white powder” produced during temperature drop

     

    ■ Humidifying distance—the thickness of the wet film itself

     

    ■ High saturation efficiency—up to 80%

     

    ■ Safe and reliable—the film material is mildew and bacteria proof, with a service life up to 8 ~ 10 years

     

    ■ Excellent cooling performance—cooling through filling-catalyzed direct evaporation; more efficient cooling with less space Wet-film Humidifying Capacity for Typical Units
