The TEC artec TECpress steam conversion station is a combination of pressure, quantity and temperature control. The subcritical controlled pressure release is integrated with the proven downstream temperature control systems into a complete solution. Due to different design versions, various applications such as turbine bypass stations or district heat extraction can be realised.

Our variTEC ball valve is used for shut-off, control and safety functions (HIPPS). The ball valve provides universal possible applications for shut-off and/or regulation of the medium. This valve is suitable for almost every application due to the wide temperature range and the design with trunnion mounted ball, Double Piston Effect and Double-Block-and-Bleed function.

Our patented desuperheater TECtemp HT V venturi cooler is suitable for applications at temperatures up to 750 °C for small pipeline nominal diameters due to non-moving parts in the steam flow. The three-part design makes it possible to bring the control unit with drive out of the high temperature range. The functional principle is based on the proven TECtemp desuperheater. The compact control unit can be removed easily and can be serviced individually for servicing work. This desuperheater is used as a compact solution for small pipelines with a high number of nozzles and small pressure loss requirements.

Our patented desuperheater TECtemp HT R ring cooler is designed with a three-part structure without moving parts and without weld seams in the steam lances. These are arranged in a ring shape depending on the steam pipe nominal diameter. For example. 40 individually controlled nozzles can be used in this way. Homogeneous distribution of the injection water makes short evaporation sections and minimal load of the steam pipe possible. The geometry of the steam lances acts like a venturi nozzle in the steam pipe which results in clearly reduced loss of pressure.

Our patented desuperheater TECtemp HT L lance cooler is suitable for applications at temperatures up to 750 °C due to non-moving parts in the steam flow. The three-part design makes it possible to bring the control unit with drive out of the high temperature area. The reduced weight of the steam lance has a positive effect on the support load of the steam line. The functional principle is based on the proved TECtemp desuperheater. The compact control unit can be removed easily and can be serviced individually for servicing work.

The patented TECsteam steam booster nozzle is used for cooling steam close to the saturated steam temperature or hot gases. The temperature is controlled by the injection of water into the steam or hot gas stream whereby the water is thermally atomised using high pressure steam. The high pressure steam is removed from and returned uncontrolled to the high pressure steam system. The temperature-dependent cooling water is supplied via a control valve. Extremely short evaporation sections of less than 3 m can be realised with this valve.

Fittings Our manufacturing site in Switzerland produces over 100 different types of fitting under cleanroom conditions in compliance with DIN 16901-140. The fitting bodies are made of PFA, while the union nuts are made of PFA, PVDF or CPFA. We stock all the connections available on the market too. Emmen cleanroom plant GEMÜ has be producing valves and fittings at its new cleanroom plant in Emmen (Canton of Lucerne, Switzerland) since September 2012. A state-of-the-art manufacturing and assembly facility was built here when, thanks to commercial success, the capacity of our site in Rotkreuz could no longer keep up with demand. When planning and developing the facility, designers focused on creating a contemporary quality management system that is fit for the future. The result is that product and production quality are ensured, for example, by using specific inspected raw materials and through audits carried out by customers and official bodies.
