FREI HYDRAULIK GMBH

These are the parts used in mechanical shaft.

Engines for combined heat and power plants are operated with different fuels, including hydrogen, natural gas, biogas, sewage gas and special gases, plus diesel and other liquid fuels. In an exhaust gas heat exchanger, the hot exhaust gas from the CHP engines or CHP gas turbines is cooled, in the process heating water, a water-glycol mixture or thermal oil. This thermal energy can be used in a local or district heating system or for other industrial purposes.

Silencers/Mufflers; diesel and gas engine exhaust noise is designed based on required target noise levels and current pressure drop. In addition to the standard silencers for stationary engines, special silencers are designed and manufactured according to customer specifications. In addition to reducing exhaust noise, extremely compact designs are made with the available space in mind.

Wire spark erosion, laser micro-cutting, micro-milling and micro-drilling STEEC is also involved, both as a subcontractor to numerous SMEs and agencies in the metallurgy and mechanical engineering sectors which very often engage in subcontracting activities themselves. STEEC enables these players to respond to invitations to tender that involve meeting precision micro-machining requirements for which they are not equipped. The wide variety of precision micro-machining operations which STEEC offers is highly beneficial to these SMEs and agencies, which are able to offer a comprehensive service in micro spark erosion, laser micro-cutting, micro-drilling and milling.
