Rotec technical enclosure in Hamburg with Renson lamella L.120.01, the ideal solution for air conditioning enclosures

The requirements for modern air conditioning unit enclosures are diverse. In addition to the aesthetic component, technical factors such as span width, material resistance and ease of installation also play a decisive role. In a completed project in Hamburg on Anckelmannstraße, Rotec was able to master these challenges with aplomb. The key role was played by the L.120.01 louvre blade from Renson, one of our long-standing premium partners.

The challenge

The special feature of this project was the requirement to find louvers that allow a free span of up to 2000 mm. This is particularly demanding, as most louvers are not designed for such large spans. However, this requirement was optimally met with the Renson L.120.01 slat.

Features of Renson slat L.120.01

The LINIUS® L.120 louvre wall system from Renson consists of extruded aluminum profiles ALMgSi0.5, a material characterized by high strength and corrosion resistance. The Z-shaped ventilation louvers also offer excellent weather protection properties and are designed for large free spans.

Surface finishes are specified specifically to the architect's specifications, ensuring a seamless transition to the surrounding architecture.



Simple assembly

Another highlight of the system is the clip mounting. The slats are simply clipped into the slat holders belonging to the system. This guarantees the linear course of the slats and makes installation much easier.
