YAM Features
The patented design of YAM series meets the EN 1886 Class(D1, L1, T2, TB2). The unit casing consists of foam injected, cold bridge free, AL frame profiles and high density polymerized polyurethane foam injected panel with edges, which are joined together with strong AL-plastic composite tri-axial angle lug.
China utility model patent No. ZL201220187540.1
The casing boasts a strong frame that is a complete metal complex of AL-plastic composite tri-axial angle lug and foam injected AL profile.
Coupling with high-quality closed cell foam synthetic rubber, the unique knife-shaped at the foam panel edge gives perfect ring seal.
The air leakage at joint is eliminated by the anti-flaming and high/low temperature resistant gasket and professional mechanical assemble.
The air leakage at the double-layer sealed access door is eliminated by reliable vehicle-using sponge sealing strip and high-strength lockers.
Double skin construction is provided by "sandwich" type with high density strip.
The foam panel and profile skins are injected with PU foam of 45kg/m3, providing a thermal conductivity coefficient lower than 0.02W/m·k.
Al profile employs nylon insulation strips design and the skin is filled with PU foam.
The damper and drain pan are fixed with strips to isolate the cold bridge.
The drain pan uses 20mm thickness synthetic rubber insulation for heat resistance and anti-condensation.
The flush-joint from the panel to frame has a smooth surface and arcs at corners to prevent dirt retention and water standing.
Drain pan is dual V-shaped structure with longitudinal slope, and allows quick and easy drainage of condensate water.
The high quality direct-driven fan (plug fan) is optional, to avoid pollution caused by wheel belt.

The roll filter is ideal for large volume applications for its longer maintenance period and lower maintenance cost that rely on its automatic filter replacement.
Direct Gas Burner Segment
For brand-new fresh air unit fan with large air quantity and high-heat application in winter or throughout the year, the Segment can effectively save initial investment and running cost.
Rapid Absorption Steam Humidifier Segment
The spray tube and orifice have reasonable arrangement, applicable for vertical and horizontal flow.
It optimizes the humidification effect by evening the steam diffusion and shortening the absorption distance.
Professional design of steam collecting tube and water collecting tube delivers the perfect steam-water separation.
It is free from steam preheating and retains no residual water in steam pipe, delivering clean humidification.
It is ideal for industries of tobacco, coating, electronics, textile, etc.

Notes for Installation
1. The AHU must have a horizontal foundation and proper vibration-isolating measure during the installation. After installation, fix the AHU with foundation bolts.
2. Important: all delivery sections must stay at the same level and no inclination shall be acceptable during the field installation. Before tightening bolts, ensure all contact surface retain the same level.
3. The foundation height must be enough to install the water trap as required and no lower than 150mm.
4. The tube near equipment must be fixed to eliminate any torque-caused damages against equipment when tubing (inlet, outlet, steam).
5. It is recommended to use flexible connectors for inlet and outlet pipes and self-closing valves (provided by customers) for steam and hot water inlets to ensure that the internal temperature is not higher than 60°C.
6. When using the crane or forklift to load/unload or position equipment, please ensure the stress points shall be lifting holes or forklift holes and no shoveling or lifting on the base or any other casing part shall be allowable.7. The electric heater must interlock with the fan when an electric heater segment exists.8. The installation of AHU water trap must follow the right figure. 9. All electrical components and shell of the AHU must be grounded.
Notes for Maintenance
1. The AHU shall be under the maintenance by specially-appointed staff.2. All electrical components and safety devices shall be regularly inspected.3. Periodically inspect and adjust the belt tension to optimize the AHU state. 4. Periodically inspect the filter DP and cleanliness and clean or replace those with over DP.5. Periodically lubricate components that need lubricating.6. Vent air in the coil before starting the unit.7. During shutdown in winter, cut off all water and steam supplies and drain off the coil or take other anti-freezing measures to
prevent coil cracking.8. Periodically clean the AHU internal and coil. The coil is cleaned by compressed air or high-pressure steam.
