This popular Holtop suspended air handling unit integrates a heat recovery system and is an ideal choice for energy-saving ventilation. It is equipped with advanced heat recovery technology, which efficiently recovers the energy from the exhaust air through a plate heat exchanger. The ultra-thin design does not occupy indoor space and is suitable for various building installations. Whether it is a commercial center, office building or hospital, it can ensure fresh indoor air and a comfortable environment in an energy-efficient manner.
Products Detail
• Equipped with supply fan and exhaust fan, brings in the fresh air and exhausts out stale indoor air as well.
• Equipped with plate heat exchanger, recovers energy from outgoing indoor air, to save operating costs.
• Thin height, easily installed in the ceiling space.
25mm thick, inner skin made of galvanized steel sheet, outer skin color steel sheet, between skins is sandwiched with high-density fireproof PU with a thermal coefficient below 0.0199W/m∙˚C
Double inlaid sealing system to tightly join the framework and panels, total air leakage rate below 3%
Outer rotor motor, direct driven centrifugal fan, dynamic balance, compact and low noise level.
Total heat or sensible heat type available for different applications. The total heat exchanger is made of special fiber paper, featured by high moisture permeability, good airtightness, excellent tear resistance, and aging resistance. Suitable for high humidity difference between conditioned space and outdoors.
The sensible heat exchanger is made of thin aluminum foil, featured by high heat conductivity and long service life. Suitable for the high-temperature difference between indoors and outdoors.
The edges of the lamina are with special plastic seals, which ensures low leakage.
Copper pipe with double-side bent wave hydrophilic aluminum foil, higher heat exchange performance.
Plate type(G2) coarse filter as standard configuration (Medium filter F5~F8 available as per request of the customer)
