Normal AHU parts consist of the following sections, which can be freely combined and mounted in casings to form complete sections: mixing air intake, filter section, heating section, cooling section, humidifying section, fan section, discharge section.

The supporting framework is made of extruded anodised aluminium and assembled by means of reinforced nylon corner joints, to get a strong and rigid structure. The double-skinned panels are internally insulated with a high effificiency, mineral wool insulation (60 kg/m3 density and more for special purpose), standard panels are in Aluzinc® and are manufactured in 25 mm or 45 mm, thickness.

Features

● Packaged framework and panels are main and special structure for the unit.
● The panels are 50 mm thick and consist of a double skinned steel sheet with intermediate mineral wool. Alu-Zinc steel or Stainless Steel is available for panel material.
● Good acoustic and thermal insulation for the unit.
● Hard fastness between panels and frame to ensure good air tightness.
● The spiroduct air pipe can be connected directly to the sections for easy installation.
● The access doors are available, which can be opened and detached easily for inspection and servicing.
● The functional sections are optional for customers, and meet the most demanding requirements.
