Description
BURE is the adjustable geometry diffuser for comfort high capacity ventilation of big halls and industrial buildings.
Suitable for heating and cooling. Installation height is between 4 m and 12 m, therefore the product is suitable for
large industrial and public halls. The air discharge pattern (horizontal or vertical) can be adjusted manually (BURE-HC),
by electric actuator (BURE-M2 and BURE-MC) or by thermal actuator (BURE-TC)
The control mechanism in HC, MC and TC version adjusts the flow pattern continuously in any selected position
between entirely horizontal and entirely vertical discharge pattern adjustment.
The M2 version controls in a section of the range that can be shifted on the adjustment scale towards the horizontal
flow pattern (in direction of pos. 1) or towards the vertical flow pattern (direction of pos. 5).
Highlights
• High capacity and very compact dimensions
• Large throw length at vertical discharge
• Small influence of geometry adjustment on pressure drop variation
• No influence of installation behind tee or elbow on the discharge pattern symmetry
Types of Product
• BURE-HC: diffuser with manual adjustment of the air discharge pattern
• BURE-M2: diffuser with 2-point or 3-point/ AC 230 V actuator
• BURE-MC: diffuser with continuous AC 24 V actuator with DC 0 V … 10 V control signal for electric remote adjustment
of the air discharge pattern
• BURE-TC: diffuser with thermal actuator for autonomous adjustment of the air discharge pattern dependent on the
actual supply air temperature
Design
The BURE is made of powder coated steel and is available in the duct connection sizes 250 mm, 315 mm, 400 mm,
500 mm and 630 mm. At underside the double segment blinds allow the free area of more than 60%.
The BURE consists of an inlet spigot and an inner and outer cage with openings for supply air in the peripheral surface
and the underside. Dependent of the operation method the openings in the peripheral surface (cooling, horizontal air
stream) or the underside (heating, vertical air stream) are opened.
