KIESEL- Heating and chilling technology

We manufacture heat exchangers of stainless steel tubes for the beverage industry. These are used for heating, cooling and energy recovery of fluid and glue products.

Our double-tube heat exchangers are made of a tubular chasing in which the cooling or heating medium flows as well an inner tube in which the viscous fluid flows. Through the corrugated tubes and the "big" reversing curves a constipation is prevented. The tube-bundle exchangers having an other tube and several small-sized inner tubes.

The size of the tubes are determined by the product, the energy source and the energy transfer task.


  • module construction system
  • easily dismounted
  • piggability
  • CIP method is possible
  • absolutely no dead space
  • expansion compensation
  • differences in temperature of over 100°C do not cause any tension
  • sliding seat with O-ring sealing
  • mounted free of tension
  • used for every sort of mash

Corrugated tubes are an essential characteristic of KIESEL heat exchangers. With their helical deformation these tubes provide strong turbulence of the energy source and the products. High terminal insulation valves are achieved.

For liquid media we produce multi-tube heat exchangers. The heat exchangers area is increased by a multiple by the inseration of several small pipes.

The thermal expansion of materials is taken into consideration during design. We are using during processing of the outer and inner tubes stainless steel material grades 304L and 316L, Hastelloy and titanium.
