Casing types

• Unit casing provides thermal and sound insulation, as well as durability and protection from external influence.
• AirVENTS series are available in several types of casing, general properties of which are:
• High Mechanical strength. Class D1 according to EN 1886.
• Corrosion Resistance. Class C4 according to ISO 12944.
• Thermal insulation. Class T3 according to EN 1886.
• Protection from thermal bridges. Class TB3 according to EN 1886.
• Increased fire resistance, high quality insulation materials. Mineral wool basalt fiber insulation with 90 kg/m³ density. Unlike other types of insulating materials, this material is completely non-flammable and environmentally friendly.

• The classic casing design is based on aluminum profile frame, joined with corners made of cast aluminum or reinforsed nylon, provides high durability of the unit. 

• Different frame thickness should be used considering the table below:

• Casing panels are made of steel sheets with a layer of thermal and acoustic insulation from mineral wool.

• The thickness of the insulation depends on the type of frame (25 or 50 mm).
• Casing panel material varies depending on unit application:

• Outer panel surface material:
• Zinc-aluminium coating (standard)
• Galvanized steel with polymeric coating (high corrosion resistance)
• Galvanized steel (for internal execution units)

• Inner panel surface material:
• Zinc-aluminium coating (standard)
• Stainless steel (for units in hygienic design)
• Galvanized steel 

• Frameless design casing system excludes thermal brigdes, usuall for aluminum or steel frame.
• This significantly increases thermal resistance and reduces heat loss, especially for outdoor installation.
• It also prevents condensation on the surface when air cooling is on.
• Casing panels made of sheet steel with a layer of 40 mm thermal and acoustic insulation from mineral wool.
• Casing material varies depending on unit application:
• Outer panel surface material:
• Zinc-aluminium coating (standard)
• Galvanized steel with polymeric coating (high corrosion resistance)
• Galvanized steel (for internal execution units)

• Inner panel surface material:
• Zinc aluminium (Standard)
• Stainless steel (for hygienic units)
• Galvanized steel

• Benefits of frameless casing:
• better thermal resistance;
• lower weight of the unit;
• no thermal bridges;
• suitable for outdoor installation;
• lower cost;
• higher mechanical strength (compared to 30mm aluminum profile frame).

• For both classic and frameless unit casing there are several types of base frame avaliable.

Adjustable legs made of 2 mm thick galvanized steel

Solid base frame made of 2 mm thick galvanized steel

Solid base frame made of 3 mm thick painted galvanized steel

Solid base frame made of 4 mmthick painted galvanized steel
