Application examples<\/h3>
 

Pretreatment Systems<\/h4>
During the pretreatment process<\/strong>, water vapour (mist) is generated, resulting in air with a high moisture and energy content. Many installations rely solely on exhaust air systems, meaning that conditioned air is discharged unused while replacement air is drawn into the building. This not only wastes energy but also creates unwanted negative pressure within the production hall.

Solution:<\/b>
Corrosion-resistant plate heat exchangers or KVS heat recovery systems combined with a supply air unit.

 

Powder coating Systems<\/h4>
High-quality powder coating systems<\/strong> require precisely controlled ambient conditions to ensure stable production processes and consistent coating quality. Air that is too dry can increase reject rates and negatively affect the coating process.

Solution:<\/b>
High-pressure humidification combined with a supply air unit including cooling.

 

Welding shops<\/h4>
Traditional extraction systems using extraction arms are often insufficient because they are not consistently positioned close to the emission source. As a result, employees may still be exposed to hazardous welding fumes and fine dust.

Solution:<\/b>
An integrated ventilation concept with source air supply at each workstation and central extraction using high-performance cartridge filters.

 

Liquid Paint Systems<\/h4>
A liquid paint system<\/strong> for drum lids generates very high solvent loads due to its large coated surface area. The production facility is located in a residential area. Although the existing installation was equipped with a thermal oxidizer (TNV), its energy consumption was extremely high.

Solution:<\/b>
A Regenerative Thermal Oxidizer (RTO)<\/strong> was implemented for the new installation. The RTO operates largely autothermally and requires little or no additional fuel. Compared to the previous solution, energy consumption was reduced by approximately 90%<\/strong>. The existing coating system was also connected to the new RTO, further increasing overall efficiency.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
