Control

The BlauAir control system can be easily integrated into various building management systems (SCADA, BMS, «smart house»).

All the information processed by a programmable logic controller, is easily accessible via standard communication protocols:

MODBUS TCP;
LON WORKS.

Any other protocol can be used according to the customer's choice and project requirements.

Casing types

Unit casing provides thermal and sound insulation, as well as durability and protection from 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.

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.

BlauAir series are available in several types of casing

BLL*: FRAME DESIGN

BLF: FRAMELESS DESIGN

* Models so marked are not Eurovent certified

BLN: SELF-SUPPORT, FRAMELESS DESIGN

BLL*: frame design

The classic casing design is based on aluminum profile frame, joined by means of cast corners, provides high durability of the unit. Different frame thickness should be used considering the table below:

Frame Type	Recommended performance area	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 unit application:

External 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

Outdoor design:

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.

Classic unit design with 50 mm zink-aluminum panels in 50 mm frame with cast aluminum corners

BLF: frameless units (Eurovent approved)

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:

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.

Frameless casing connection

BLN: self-support, frameless, modular units

Improved self-supporting, frameless, modular construction of the case with PVC profile system, eliminates thermal bridges, reduces heat loss and decreases noise level.

Casing panels made of sheet steel with a layer of 50 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:

PVC profile system inside the unit casing
Zinc aluminium (Standard)
Galvanized steel with polymeric coating
Galvanized steel

Benefits of frameless casing:

Better thermal resistance. Class T2, according to EN 1886.
Protection from thermal bridges. Class TB3, according to EN 1886.
Higher mechanical strength. Class D1, according to EN 1886.
Minimizing air leakage. Class L1, according to EN 1886.
