Extraction Systems for the Metal Industry
Reinders Extraction Systems is the leading expert for extraction systems in the metal industry. Our installations remove welding fumes and welding gases in a reliable, effective and safe way.
At Reinders we are experts in ATEX and ensure all our installations are fire and explosion safe. We can custom build any type of installation due to our flexible and modular construction system.
Extraction and Filtration in the Metal Industry
Welding produces welding gases and welding fumes that are harmful to the health of your employees. Reinders Extraction Systems designs machines that can remove these welding fumes and gases in an effective and safe way.
All our installations are:
- Custom-built
- High quality
- Flexible and modular
- Fire safe
- Easy to install
- Energy efficient
- Environmentally friendly
Many of our extraction and filtration systems for the metal industry are custom-built. They are characterized by a flexible modular construction. Because they are easy to connect, the installation can easily be adapted to any development.
Welding Fume Extraction
The law stipulates that the limit value (formerly maximum acceptable concentration or MAC value) of welding fumes per 8-hour working day is 1mg per m3. A welder typically protects himself with personal protective equipment. Welding extraction protects his colleagues who are not welding. A good extraction system is therefore of great importance.
Welding fume extraction can be done in two different ways:
- Point extraction
With point extraction (also known as spot extraction or source extraction), the welding gases and fumes are extracted directly at the source. This prevents the harmful gases from spreading further in the room. - Spatial extraction
With spatial extraction, the entire space is ventilated. Spatial extraction is usually chosen when point extraction is not possible.
Point Extraction (or spot extraction)
Spot or source extraction involves the use of stationary(centrally or locally located) units or mobile units that tackle the problem where it arises.
Source extraction exists in the form of extraction arms that can be flexibly adjusted to extract welding fumes close to the welding point and grinding, cutting and welding tables with bottom extraction.
Spatial Extraction
There are two different types of spatial welding fume extraction:
- Mixing system
When extracting welding fumes by means of a mixing system, the mixing unit at the top of the hall moves so much air that no welding fume blanket can form. The mixing ensures an evenly distributed and very low (max. 1 mg/m3) concentration of welding fumes throughout the hall. By additionally filtering and/or changing the air, the required low concentration remains below the legally required limit value. - Push-pull system
When extracting welding fumes by means of a push-pull system, clean air is blown into the hall through a blow-in channel. The clean air drives the polluted air to the extraction grille, after which the air is filtered by a filter box. The filtered air is blown back into the hall and the process begins again. The legally required part of 1/3rd refreshment can be achieved with, for example, roof fans.
Central Extraction System for the Welding Hall
In a central extraction system, several extraction arms and extraction units are connected to one filter box. This can offer advantages in terms of installation, maintenance, cost and flexibility.
