The most simple static mixer / heat exchanger is the monotube version.
It can be used as a heat exchanger or reactor for applications requiring a continuous mixing. Furthermore, the flow is usually laminar or the products to be handled are mostly of medium or high viscosity.
The product stream is flowing through the inner pipe. The heat carrier medium for cooling or heating the product circulates between the inner and outer pipe. The inner pipe through which the product flows is filled with static mixing elements, creating a radial mixing effect. The result is a considerably increased heat transfer and a narrow residence time distribution. A continuous renewal of the thermal boundary layer on the piping wall prevents thermal damages of heat sensitive products.
The monotube SMXL™ mixer heat exchanger is used for pilot units or small industrial rates for cooling, heating and temperature controlled reaction applications.
