Ventilation/filtration system main heat source

K.S. Smede og Montage based in Taastrup, Denmark supplies all kinds of forging and assembly work. Blacksmith K.S. specialises in steel constructions, repairs, railings, spiral staircases, handrails, platforms, etc.

The challenge

K.S. Smede og Montage, a smith’s working-place, was about to expand their business and move to new premises. As they were expanding, K.S. Smede og Montage took this opportunity to purchase a new ventilation/filtration system to extract welding fumes and grinding dust more effective.

One of the main requirements was that the primary heat source in the workshop must become this new ventilation/filtration system. The second requirement was flexibility. Therefore, K.S. Smede og Montage choose the most effective solution: at source extraction. Seven extraction arms were spread throughout the workshop connected to a ductwork system. K.S. Smede og Montage insisted on several other - very acceptable - requirements; the extraction arms needed to be easy to operate and should have a good quality-to-cost ratio. K.S. Smede og Montage installed the system their selves with instructions of the supplier.

The solution

The choice was crystal clear: a MultiDust® Bank filtration system, combined with extraction arms, type FlexMax. The system contains: 7 KUA extraction arms, extended with FlexMax extension cranes. FlexMax is the perfect extractor for welding high objects. For example, objects (at height) either close to or far from the mounting point of the arm. This extraction arm can be positioned in one simple movement, anywhere within a radius of approx. 9 m width up to 8 m high.

The cleaned indoor air is being redirected into the workshop, functioning as a primary heat source. Often, valuable, extracted air is channeled outside. Heat recovery was the ultimate goal of K.S. Smede og.

The extraction system is controlled on demand via three frequency converters and a joint PLC board, saving energy.

Dansk Procesventilation gave advice and finally designed the extraction system. The distributor prepared the necessary drawings for the installation.
