20 years vacuum spray-tube degassing

Gas inclusions not only interfere with the operational safety of heating and cooling systems, they also have a massive impact on the efficiency of energy transmission. So how can air and gases be effectively removed from the system water? This question marks the beginning of Servitec's success story.

Highlights of the anniversary year:

  • 20 years of expertise and maximum efficiency thanks to vaccum spray-tube technology
  • Product news: Servitec S for medium-sized systems
  • Optimized product portfolio – the right soltion for every application area

Milestones of Servitec innovations

  • The idea

    How can air and gases be effectively removed from system water? This question marks the beginning of Servitec’s success story. Creative engineers teamed up with scientists from the Institute of Power Engineering at the Technical University of Dresden in the quest for solutions. The wish list was long: establishing optimum operating conditions, ensuring safe System operation, user-friendliness, significantly increasing energy efficiency and all this as a retrofitting solution. After three years of research and development, the time had fi nally come: Servitec entered the market.

  • The technology

    Which technology is the most efficient? And why a vacuum spray-tube? According to Henry’s law, the amount of gas dissolved in a liquid depends on the temperature and pressure the liquid is subject to. Servitec’s engineers harnessed this law. Since the solubility of gases in a vacuum is virtually zero, it quickly became clear that degassing had to take place in a vacuum. But degassing was slow, after all a vacuum is inactive, almost lenitic. So they set the water in motion, by spraying it. The result: vacuum spray-tube technology!

     

  • Our mission

    “Our heating keeps on breaking down.“ Calls like this are the first key sign for Servitec sales reps. They explain with conviction how the spray-tube degassing system works and the huge advantages it harbours. The heaters run reliably, smoothly and safe. Servitec also reduces corrosion and sludge formation in the supply pipes. Tirelessly, too: in twenty years of continuous operation, the first Servitec recorded 130,000 cycles of vacuum, spraying and degassing. The passion of our sales force remains unbroken – only nowadays – so they tell us – you don’t have to explain to anyone what Servitec is anymore. It is state of the art.

  • Our success

    The modern Reflex Control concept enables fully automatic operation with a data interface for integration into modern building management and connection with other Reflex products. To this very day, spray-tube degassing remains a technical benchmark for the optimum operation of heating and cooling systems. And Servitec has long since arrived in the digital age. Systems that are far away? No qualified personnel on site? With the Reflex Control Remote, Servitec is easy to monitor – securely, quickly and from anywhere. And now, in its anniversary year, the new Reflex Control Smart App is the latest innovation: it allows easy commissioning and control of the Servitec Mini and Servitec S by app. Happy Birthday, Servitec!

Efficiency made by Reflex

Prooved efficiency – Up to 10,6 % energy savings with Servitec

More efficiency means less environmental impact, lower costs and yet full climate comfort. Reflex Winkelmann offers product solutions that increase the efficiency of heating and cooling systems by up to 10.6 %. The results were determined by an independent company, the ifes Institute (Institute for Applied Energy Simulation and Facility Management), and verified by TÜV Nord. Another benefit for the environment and economy: Servitec not only saves emissions and energy costs but also maintenance and investment costs. Learn more.
