Definitions

  • the present invention relates to a heat exchanger module and a heat exchanger system comprising it.
  • the heat exchanger module and the heat exchanger system are configured to exchange heat between a different media (a first fluid and a second fluid).
  • the heat exchanger module may be used for preheating media, such as liquid manure, industrial process water, sludge and/or ooze, intended to be used in a process e.g. for biogas production.
  • Heat exchangers are normally applied to reuse energy and the use of heat exchangers therefore limits the amount of energy wasted in production pipelines.
  • Heat exchangers may exchange heat between different media in such a manner that heat energy from waste materials may be used to heat starting materials or products before entering the production pipeline. Accordingly, the application of heat exchangers can reduce the energy needed for carrying out the production.
