Cooling of polymer melt
SMR mixer / heat exchanger
SMR mixer / heat exchanger
Cooling of a polymer melt or solution is a difficult application as the viscosity of the product between in- and outlet increases. In some cases this effect could be very pronounced. There is also danger of maldistribution. Sulzer India has the know-how to find a solution for this difficult task and will accordingly design the most appropriate heat exchanger.

There are two types of mixer-heat exchangers to fulfil this duty. The Multi tube mixer heat exchanger SMXL® for moderate viscosity increases and the SMR® for higher viscosity increases.


SMXL multitube mixer / heat exchanger

Typical applications:

  • Cooling of Silcone oil and Silicone rubber prior to filling
  • Cooling of Hot Melt, adhesive solutions and thermoplastic melts
  • Cooling of fiber prior to spinning installation
  • Adjusting of the viscosity prior to a downstream process step

Customer advantages:

  • Efficient heat transfer task backed by process guarantee
  • Special tailored design to match customer specification
  • Low shear rate
  • Low pressure drop if required
  • Quick change from one product grade to another
  • Homogenous Product Temperature
  • Lower energy consumption compared to dynamic heat exchangers
  • Much lower investment cost compared to traditional dynamic heat exchangers
