Application examples:<\/h3>

 <\/p>\r\n

Pre-treatment<\/h4>\r\n

In pre-treatment systems, steam, also known as mist, is produced. The energy content of the air is very high due to the humidity. Most often, only exhaust air systems are planned. Compensation through fresh air is omitted, and the energy escapes unused through the roof. The negative pressure in the hall is also not compensated.<\/p>\r\n

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

 <\/p>\r\n

Powder coating<\/h4>\r\n

When the highest qualities are required, the air must also meet these standards. Consistent conditions are essential to keep the process stable. Air that is too dry leads to higher rejection rates.<\/p>\r\n

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

 <\/p>\r\n

Welding shop<\/h4>\r\n

In the past, extraction systems with extraction arms were often used. Nowadays, it is evident that these are not used efficiently enough and therefore do not sufficiently protect employees from toxic dust.<\/p>\r\n

Solution:<\/b>
Integral ventilation concept with source supply air at the workplaces and central extraction with cartridge filters.<\/p>

 <\/p>\r\n

Painting system<\/h4>\r\n

A painting system for drum lids has a very high throughput of surface area and thus solvents. The facility is located in a residential area. The existing system has thermal afterburning (TNV), but this consumes vast amounts of energy.<\/p>\r\n

Solution:<\/b>
A regenerative thermal oxidation system (RTO) was planned for the new system. The RTO is mostly autothermal and does not require additional fuel. The new system has a 90% reduced energy consumption. Additionally, the existing system was also connected to the new RTO.<\/p>\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
