Air Handling Unit Features

Characteristics of air handling units: 

Frame 
It adopts highstrength aluminum alloy profiles which foaming polyurethane is injected. By using special polymer reinforced resin clamping piece, the section material is connected to form the frame.So the entire unit has the advantages of high strength, light weight, corrosion resistance and long lifetime. In addition, it has beautiful appearance and flexible structure and is easy for disassembling and repairing. 

Panel 
The panel is double skin. External surface panel is highgrade electrolytic plate whose surface is sprayed plastic. Internal surface is galvanized steel sheet. Thermal insulation materials is polyurethane foam with density 40kg/m3. The thickness of the panel is 40mm,to guarantee high thermal insulation, air tightness and low tendency of condensation.
