High strength, high reliability
Panels are double-skin with injection of high density polyurethane. The outer skin is anti-corrosion color-coated steel sheet, the inner skin is galvanized steel sheet. The unit cabinet consists of panels attaching to each other by combining with male and female aluminum alloy cards and sealing strip, tighten with concealed bolts.

State-of-the-art design
The outer skin is colored steel sheet with anti-corrosion coat and is cleanable; the fastening bolts are concealed by plastic caps. The outer layer of film prevents panels from scratching during unit assembling and transportation. Clear, smooth and color coordination appearance make the outlook attractive.

Outstanding cold-bridge free structure
The density of polyurethane injection is 50kg /m3 (thermal conductivity factor K≤0.0224W/m²·K). Unit cabinet is constructed by panels with male and female aluminum alloy cards and sealing strip. The service door (or service panel) is plastic-steel frame with polyurethane injection panel and rubber sealing strip.

Low air leakage rate
Double skin panel, unitary structure design, less connecting joints, multi sealing strips in the contact surfaces, around sealing service door/ panel, all ensure almost total air can be supplied to the air-conditioned room. The air leakage rate is less than 0.29%. Units will not sweat when exterior room temperature is 27°C, relative humidity is 90%.

High performance heat exchanger
Copper pipe and aluminum fin type heat exchanger, optimal choice of fin spacing and number of rows. Fins are coated with anticorrosive layers, assure longer coil life and lower maintenance cost. Optimal water circuits design, increased heat exchange efficiency and decreased water resistance, improving unit performance efficiency.

Stable air supply fan assembly
Yilida brand centrifugal fan, high performance efficiency, 3-phase, class “F” insulation and IP54 protection AC motor.
Belt drive, optimal selection of drive ratio, increase fan/motor assembly efficiency, easy for maintenance.
Service door or service panel is equipped for inspection of motor and fan.

Low noise design
Optimal fan selection, excellent working condition, efficient operation.
Flexible connection at air outlet, minimizes vibration transmission.
Equiped with shock absorbers, decreases vibration, low noise. Tight cabinet, secures against noise leakage.

Improved indoor air quality
Aluminum alloy frame plate type filter, stable and durable covers the whole return air inlet, large filter surface, higher inlet air quality.
Filter can be extracted in leftward and rightward way, easy for maintenance.
