The HLU range of products

We offer an extensive range of products made of corrosion-resistant plastic.
These products are used everywhere in areas in which chemical resistance, reliability and long service life are required.

For more than 85 years, we have been developing, designing and manufacturing industrial and laboratory fans with corresponding components, such as sound insulation enclosures, control and shut-off valves as well as pipe and duct parts for air technology.


Our central AHUs guarantee efficient energy recovery for exhaust air contaminated by chemicals. Our products are also used in apparatus and container engineering (plastic equipment engineering)
