Külling

3-in-1 extraction system for concrete dust

Külling AG has been a major player in the production of concrete elements and artificial stone in Switzerland since 1910. The product portfolio includes stairs, window surrounds, concrete pipes, columns and façades. The approximately 80 employees implement major projects for companies and local authorities as well as private construction projects. Once the concrete parts have been poured and hardened, the surfaces are ground smooth. This releases an immense amount of concrete dust and aerosols due to the use of water in the grinding process.

As part of the production expansion, the Swiss company was looking for a dust extraction solution for five manual workstations and two large sanding machines. Dust turbulence caused by opening doors and windows should also be avoided by controlling the air flow.

INDUSTRY

Concrete element and artificial stone production

PROCESSES

Wet sanding
Wet polishing

MEDIA

Concrete dust & water mist

Requirement:

  • Extraction and filtering of moist concrete dust
  • Filtering large quantities of dust
  • No clogging of the filters overnight
  • Reduction of humidity and condensation
  • Constant air flow even with open doors and windows
  • Low maintenance and cleaning effort
  • Automatic discharge system for large quantities of dust

Our extraction solution:

3-in-1 solution

The combination of wet separators, pipe system and fresh air supply is a single unit and therefore perfectly coordinated in terms of energy and technology.

Simple filter cleaning

The filter stages have an automatic cleaning system or can simply be washed out manually.

Time-controlled discharge

The filtered dust is automatically discharged as sludge via a pinch valve, dewatered and can then be disposed of.

Result:

✓ Air pollution control & fresh air

The dust is filtered efficiently, allowing doors and windows to remain closed.

✓ Reduced air humidity

The automatic fresh air supply and summer/winter switch reduce the humidity in the hall.

✓ Energy-saving operation

The combination of recirculated air, exhaust air, summer/winter switching and an optimally planned pipe system saves a lot of energy and costs.

The complete solution from ABSAUGWERK has convinced us!

»If intensive sanding is carried out, the air in the hall is still completely replaced after a few minutes. We used to have to open the hall doors. This was very cold, especially in winter, and not ideal in terms of energy. Energy always plays a role these days. If the system is economical in terms of consumption, then of course it pays off. Maintenance was a very relevant criterion for us, especially with regard to filter cleaning and replacement. We enquired with various providers, but the complete solution from ABSAUGWERK convinced us the most.«
