The challenge

Hörmann develops and produces doors of every imaginable type, including doors for the industrial market, such as dock seals for loading and unloading lorries, as well as garage and interior doors for the consumer market.

In their Alkmaar (Netherlands) factory Hörmann manufactures products such as dock levellers, dock shelters, dock and highspeed doors, and dock seals. In 2007, Hörmann expanded two production halls by an additional 2,000 m2. Today around 100 employees work at this location.

The expansion included the purchase of new welding robots to optimise the production processes in Alkmaar. Plymovent was then contacted for welding fume extraction systems.

The solution

The Plymovent FlexHood extraction hood is specially designed for welding robots. An extraction hood with welding strips is an ideal product for isolating a welding machine from the rest of the work floor. This enables you to protect the people nearby and ensure that all the welding fumes remain within the extraction hood.

The choice for welding hoods was an easy one.

The SCS system was chosen as filtration system, because the welding fumes at Hörmann contain no oils. Ductwork connects the four extraction hoods to the SCS filter system. Because the system is equipped with frequency-controlled dampers it is also extra energy-efficient.

The contaminated air is filtered in the SCS system and then recirculated, which means the air is cleaned and then blown back into the workspace. This prevents valuable energy from being wasted.

The extraction hoods are suspended from the existing steel construction. This also makes optimum use of the workspace, without the need to install optional stands on the floor.

Testimonial

Quote by Mr. Alexander Oud of Hörmann Alkmaar BV: “We are extremely satisfied with the Plymovent extraction hoods. They were built to our exact dimensions. This means that only welding fumes are extracted, precisely where needed, in a screened-off area directly above the welding robot. The welding fumes are drawn off well, keeping the working environment clean and therefore safe.” “We also opted for recirculation. This means that the welding fumes are first filtered. Then the clean (pre-warmed) air is blown back into the work area. This considerably reduces the ventilation and electricity costs.”
