Over 60 years of experience in flue gas cleaning and dedusting technology.

The company's history began with the manufacture of sheet metal piping for ventilation systems. Over time, this developed into our own product range: central vacuum cleaners, dedusting systems, silo top filters and pneumatic conveyors for every conceivable application. Complete flue gas cleaning systems with pipes, chimneys and heat exchangers round off the product range.

Robust technology is used to keep the air clean, which proves itself in practice day after day. Thanks to its own production facilities, Hellmich can react quickly and flexibly when required. More than 1,000 flue gas cleaning systems and over 1,400 dedusting systems in operation worldwide are proof of the high product quality. In most cases, the legally prescribed limit values are far exceeded.

All systems are produced at the Kirchlengern /NRW site with a high degree of vertical integration and are installed and commissioned by the customer's specialists. Hellmich thus offers a 360° concept from planning to commissioning. So that the air stays clean.
