  • 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.

  • 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.

Our desuperheater enable very precise regulation of injection water amounts for the hot steam cooling. The special nozzle design and individual actuation uses a 90° rotary movement and ensures constant microfine atomisation of the injection water. The shut-off is performed with TECtemp HD by using an integrated ball / seat ring system outside the high thermally loaded zone. High differential pressures between injection water and process steam of, e.g. 100 bar are realized using multi-stage pressure reduction. The use of coating materials with a high resistance to wear is increasing the life cycles significantly.

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.

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 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 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.

Power plant application areas



Conventional power plants are used for electricity generation. For example, these include lignite, hard coal or gas power plants. Very different types of primary energy are converted to electric current in a power plant.
Basic functionality: Water is heated by combustion in the steam generator in the core of the power plant. Turbines are driven at very high pressure and temperature with the steam produced from this. These are coupled to electricity generators. Afterwards, the steam is condensed to water and returns to the steam generator.

Valves from TEC artec have been used successfully for many years in many national and also international industrial and large power plants.

Gas application areas



Valves in gas networks are important shut-off or control valves with high requirements for operational safety and reliability. For example, our valves are used in compressor stations.
