Casing types

Unit casing provides thermal and sound insulation, as well as protection and resistance to external influence. BlauAir series are available in several types of casing, general properties of which are:
  • High mechanical strength.
  • Corrosion resistance.
  • Thermal insulation.
  • Protection from thermal bridges.
  Mineral wool basalt fiber insulation with 90 kg/m³ density is applied for casings. Unlike other types of insulating materials, this one is completely non-flammable and environmentally friendly.

FRAME DESIGN *

The classic casing design, based on aluminum profile frame and joined by means of cast corners, provides high durability of the unit. Different frame thickness should be used depending on the unit size.

Frame type Recommended area of performance Aluminum profile thickness Thermal insulation thickness
50-50 20000-45000 m³/h 50 mm 50 mm
70-50 more than 45000 m³/h 70 mm 50 mm

Casing panels are made of steel sheets with a layer of thermal and acoustic insulation from mineral wool. Casing panel material varies depending on the unit application:

EXTERNAL PANEL SURFACE MATERIAL: Zinc-aluminium coating (standard); Galvanized steel with polymeric coating (high corrosion resistance); Galvanized steel (for internal realization units).

INNER PANEL SURFACE MATERIAL: Zinc-aluminium coating (standard); Stainless steel (for units in hygienic design); Galvanized steel

EXTERNAL REALIZATION: The unit is additionally protected against atmospheric precipitation. Weather protection hoods are provided at the inlet and outlet air pipes. Air damper actuators are supplied with protective visors. Flat or gable roof. An inspection window is supplied with a protective grille. The visor length is 300 mm. All joints are sealed. All these elements protect the unit against external influence of water, send, leaves, etc.

FRAMELESS DESIGN – APPROVED EUROVENT

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 are made of sheet steel with a layer of 40 mm thermal and acoustic insulation from mineral wool. Casing material varies depending on unit application.

EXTERNAL PANEL SURFACE MATERIAL: Zinc-aluminium coating (standard); Galvanized steel with polymeric coating (high corrosion resistance); Galvanized steel (for indoor units).

INNER PANEL SURFACE MATERIAL: Zinc aluminium (standard); Stainless steel (for hygienic units); Galvanized steel.

BENEFITS OF FRAMELESS CASING: Better thermal resistance. Class T3, according to EN 1886. Protection from thermal bridges. Class TB4, according to EN 1886. Higher mechanical strength. Class D1, according to EN 1886. Minimizing air leakage. Class L1, according to EN 1886. Lower weight of the unit. Suitable for outdoor installation.
