STRIKO heat exchangers are especially designed for tempering viscous to highly viscous media – reliably and smoothly up to a range of 500,000 mPas. The applications are thus broadly diversified – the cooling of silicon, bitumen or hexane, the heating of static mixer during chocolate production and the tempering of plastic melts are all part of it.

Service description

The special feature of the heat exchanger models is the use of helical mixing elements in the product room pipes. This prevents sticking or fouling of product at the pipe interior wall, because their product mass is constantly mixed and turned. This effect also occurred for one-digit reynold numbers. There are different options of integrating the mixing element chains of the Helical type in the product room pipes:

  • slide-in, designed as removable – the most widespread solution (e.g. for cleaning, control, revision)
  • slide-in, firmly welded to the pipe interior wall
  • shrink wrapped (for better heat transfer)
  • soldered (for optimum heat transfer, high axial load ability, no gaps)
