Condensate Cooling and Safety System

Main Features

  • Finned tube heat exchanger type using steam to heat up gaseous media (e.g. air)
  • Customized according to client specification and request (e.g. equippable with air pre-heater recuperator or with optional electrical or oil heater to reach higher temperatures)
  • Insulated housing (fully welded, sanitary design) and extractable elements
  • Condensate cooling and innovative safety system (see below)

Materials And Characteristic Values

  • Housing: Stainless steel (AISI 304 or AISI 316) with mineral wool insulation
  • Finned tubes: Stainless steel (AISI 304 or AISI 316)
  • Fins: Aluminum or stainless steel
  • Air volume: up to 150’000 kg/h per device
  • Discharge temperature: 80 to over 200 °C, depending on steam pressure, or more than 300°C with optional electrical or oil heater
  • Steam pressure: up to 70 bar

Condensate Cooling

  • Use of flash steam and condensate of the steam coils to pre-heat the process air
  • Separate flash steam and separate condensate stage, for stable running conditions at different capacities
  • Returning of water without any flash steam to the tank

Safety System

  • Innovative and field-proven system consisting of pressure sensors, valves and bypass piping
  • To avoid steam hammers which caused a quite long history of damage at steam heat exchanger units without safety system
  • Steam hammers occur when the heater coils fill up with water especially during low capacity cases
