Customer and Environmental Benefits

  • Reducing energy consumption
  • Optimizing plant maintenance
  • Improving reliability
  • Implementing the latest control technologies
  • Compliance with environmental protection regulations
  • Integration of emission controls
  • Ensuring the lowest possible Total Cost of Ownership (TCO)

Jet Evaporator

  • Shorter Heating respective Drying times due to very high steam speed inside the autoclave.
  • Small temperature differences on the drying object at the end of the heating up phase due to improved heat transfer values (alpha) resulting in better Drying results.
  • More homogeneous humidity profiles respectively smaller differences in the humidity Content on the drying object.
  • Higher Condensation temperature at the drying object as there are no flow losses, as the high vapour flow speed is induced by the solvent injected at high speeds.
  • Higher drying temperatures on areas with reduced Vapour access due to high turbulence resulting in increased Diffusion coefficient.

Process end Determination

PLC controlled measuring device for measuring the water vapour partial pressure in a vacuum system. The device serves for recording the pumped off residual humidity from the insulation and thus also for the determination of the process end when Drying transformers or capacitors. (Determination of specific water extraction)

In summary, Vapor Phase Technology offers a range of improvements and advantages that lead to more efficient and effective drying processes. The integration of JET evaporators, APRS, multi-stage vacuum units, and advanced measuring and control systems allows for precise process control and optimized results. The application of this technology in transformer manufacturing helps to increase the life and performance of oil-paper insulation while minimizing energy consumption and solvent loss.
