Roerwerken voor Zoutman
Every year, ZOUTMAN uses about 35,000m³ of water for their production process (at their site in Roeselare). Because raw sea salt contains residues such as sand, shells, etc., it is necessary to rinse the sea salt thoroughly with water.
The installation of the new Ekopak brine plant allows Zoutman to reuse this process water & brine.
CGK Group stood in as supplier for Ekopak.
We successfully delivered 8 agitators mounted on 5 plastic carriers.
Additional challenges?
- Corrosive environment: all materials had to withstand ZOUTMAN's corrosive environment.
- Temperature variations: The agitators are located inside a building where mixing temperatures vary from 5°C in winter to 25°C in summer. This placed additional demands on materials and construction.
- Specific colour and coating requirements: The client required all engines to meet specific colour and coating requirements.
Oplossingen
- Motor shafts and impeller blades: manufactured from high-grade stainless steel 316L for excellent resistance to rust and wear, to ensure durability and reliability, even in changing temperatures.
- Plastic carriers: designed with a flat bottom for extra stability and optimal mixing results.
- Baffles: specially designed and installed in the tanks to match the proposed impeller blades for efficient mixing performance.
- Electric motors: painted in RAL1015 and coated with C4 to ensure durability and corrosion protection.
