Main features: • 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.Housing construction a. Double skin panel 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 b. High airtightness Double inlaid sealing system to tightly join the framework and panels, total air leakage rate below 3% Supply fan and exhaust fan Outer rotor motor, direct driven centrifugal fan, dynamic balance, compact and low noise level. Heat exchangers
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.
Airflow damper (optional)
The edges of the lamina are with special plastic seals, which ensures low leakage.
Manual or motorized control is available for options.
Water cooling/heating coil
Copper pipe with double-side bent wave hydrophilic aluminum foil, higher heat exchange performance.
Air releaser and drainage plug are set in pipe connection box to ensure return path free from accumulated air, convenient for maintenance in winter.
Filter
Plate type(G2) coarse filter as standard configuration (Medium filter F5~F8 available as per request of the customer)
Draw-push installation, easy maintenance.
ELECTRICAL CONTROL
Standardly, we do not offer control boxes and related control components for AHUs but offer wiring terminals only. Besides, we offer the following control system as options. • Independent run/stop of supply fan and exhaust fan • Water switch control and temperature control • LCD thermostat controller • DDC (PLC) controller is optional
