Multitube heat exchanger SMXL™

Increase heat transfer efficiency for viscous products

In addition to the monotube SMXL, we also offer a multitube mixer-heat exchanger, which offers improved heating or cooling of viscous media at high throughputs. It is the perfect alternative when the flow is too high to be handled in a monotube.

Main benefits
  • Increased heat transfer coefficient for highly viscous products
  • Narrow residence time distribution
  • Low shear rate
  • Gentle treatment due to short residence time
  • Quick change from one product grade to another
Main applications
  • Mainly for heating and partly for cooling applications
  • Especially for heat-sensitive and/or viscous products
Key characteristics

The main stream is divided into several partial pipe streams with the same operation mode as the monotube design. In contrast to a monotube heat exchanger, the SMXL Multitube heat exchanger has no restrictions with regard to product throughput or heat to be transferred.

The multitube mixer heat exchanger type SMXL is used mainly for heating and partly for cooling applications especially for heat-sensitive and/or viscous products. A special application is preheating of a polymer solution, where part of the product starts to evaporate already in the heat exchanger, for example prior to entering the devolatilization vessel.
