hrsfunke tt tube

With this type of heat exchanger the smaller inner tube and larger outer tube carry the service media whilst the process media passes through the annulus between the two tubes. The tube diameters range from 1” inner tubes to 6” outer tubes as standard, with unit lengths available in three or six metres. Manufactured from AISI 304 / 316 stainless steel the HRSFUNKE TT Tube uses innovative corrugated tube technology. Three types of corrugation are available, dimple for low Reynolds numbers, hard corrugation for high Reynolds numbers and soft corrugation for medium Reynolds numbers.

  • Heat transfer coefficients of up to 2½ times higher can be generated.
  • There is no significant obstruction to the flow area of the tube so that they can be used for fluids with a high solid or fibre content with no fear of blockage.
  • Increasing the tube side heat transfer coefficient brings the temperature of the tube wall closer to the temperature of the bulk fluid, minimising fouling.
  • Due to the higher coefficients achieved, heat exchanger size can be reduced by as much as half.
  • In-situ cleaning is improved because of the increased turbulence generated by the corrugated tube, which in lower viscosity fluids minimises the tendency for deposition fouling to occur. If fouling does occur the deposits are normally very easy to remove since corrugation leads to an uneven film thickness.
