About us
Optima Energietechnik und Anlagenbau GmbH is an engineering office founded in 1981 and based in Spangenberg (North Hesse). The company supports projects in energy generation and distribution from consulting through preliminary and permitting design to implementation, including support with tendering, procurement of funding and expert reports. Focus areas are the planning of new plants as well as the optimization of energy generation plants and heat networks in existing industrial and commercial structures – from power plant technology and steam boiler systems to biomass heating plants. In addition, Optima offers non-invasive ultrasonic measurement technology (Flexim FLUXUS) for flow rate and heat quantity measurements, for example on thermal oil at up to around 270 °C, as well as measurement services for the hydraulic balancing of heating and cooling networks. Further services include plant relocations of mobile heating centers and their integration into existing networks. Reference customers include companies from the furniture, veneer and pharmaceutical industries as well as energy suppliers and the ADAC headquarters in Frankfurt am Main.
