PQ ENGINEERING
Our mission: Stable energy for your success
When there are flickering and shimmering noises, unusual noises are heard, or threshold values are violated, the high susceptibility to failure of an otherwise thoroughly fascinating technology becomes apparent. Minimizing this susceptibility to failure and helping companies and operators of critical infrastructure achieve optimal and uninterrupted workflows has always been and remains a fundamental concern.
Dipl.-Ing. Ralf Nosswitz, Managing Director of PQ ENGINEERING


From regional engineering forge to global expert
Founded in the 1970s by Frank Nosswitz, PQ ENGINEERING has evolved from a regionally based engineering firm into a globally operating service provider for energy supply and grid stability. What distinguished the family business decades ago still holds true today: quality, reliability, and well-trained specialists who continually update their knowledge and skills to offer customers the best possible solutions form the basis of all business activities.
Added to this are modern devices and internally developed solutions such as the modular hybrid filter system PQE hMF, the broadband module PQE UBM or the universal broadband filter PQE uBF, which have set new standards in power quality.
