Über uns

Fritzmeier UmwelttechnikInnovative solutions for humans and the environment

Fritzmeier has been synonymous with progress since 1926. Founded as a saddlery business, the company made farmers' working lives more comfortable with fully suspended tractor seats and the first tarpaulin covers. Another revolutionary step forwards was made in the 1960s with the development of the tractor rollover bar. Fritzmeier established itself as the global market leader for cabs for construction machinery and forklift trucks.
Picking up from where it all began: Fritzmeier Umwelttechnik has been developing innovative solutions for people and the environment in the old saddlery workshop since 2012. 

COALSIYou can count on us.

COALSI is a leading system solutions supplier for exhaust air, odour and extraneous water problems. Fritzmeier Umwelttechnik brings together expertise in plastics manufacturing and bacterial fermentation.
Arising from this synergy, the COALSI brand was incorporated into the company in 2010. The original filter technology has been further developed to today's hybrid activated carbon filter with triple filtration.
The COALSI system solution combines physical, chemical and biological methods. As a result, only harmless and barely perceptible substances can pass through the filter. Products for rainwater retention in foul or combined drainage systems complete the range.
