Louvered hood offering the highest level of protection

BerlinerLuft. Technik GmbH has comprehensively redesigned and technically enhanced its DHE/LH louvered hood.
An optional version of the louvered hood is now resistant to driving rain and certified in accordance with DIN EN 13030, Class A – the highest protection class.

This class defines a deflection efficiency of 1 to a minimum of 0.99, allowing a maximum water ingress of 0.75 liters per square meter of hood surface per hour. The driving-rain-proof version of the louvered hood (DHE/LH-SRS) from the HVAC specialist performed even better in testing: all tested configurations achieved an efficiency rating of 1. The test certificate confirms a water ingress of exactly 0 liters per square meter. In other words, the hood remained completely dry during testing – even under simulated heavy rain with wind speeds of 13 m/s.
 

“With the Class A certification, we are setting new benchmarks in driving rain protection. Operators of industrial and commercial facilities can rely on our driving-rain-proof louvered hood to provide uncompromising and reliable protection even under extreme weather conditions,”
says Karsten Bruns, Product Manager at BerlinerLuft. Technik GmbH.
 

Versatile applications

The louvered hood (DHE/LH) is a square roof hood designed for outdoor air intake and exhaust air discharge in HVAC systems. In its driving-rain-proof version (DHE/LH-SRS), it is frequently used for the ventilation of sensitive technical areas such as server rooms, control cabinets, or cleanrooms for semiconductor manufacturing. It reliably protects against moisture wherever any water ingress must be avoided, even when condensate drainage is provided in the downstream duct system.

Technically enhanced

The new louvered hood design combines a robust substructure with precision-engineered louvers. At the corners, the louvers are accurately butt-jointed, ensuring a tight and clean finish. A bird protection grille positioned behind the louvers additionally prevents foreign objects or animals from entering the hood. A slightly sloped roof with a drip edge further improves rainwater runoff efficiency.
