In the Poly-Mixchanger an array of flattened and twisted mixing tubes are enclosed in a common shell.  Hipex constructs these units with removable tube bundles so that product can be processed on both the shell and tube sides.  This makes the unit more suitable than the single element for non-particulate product heat recovery and larger flow rates.

Hipex can custom design a Poly-Mixchanger for your particular requirements. The unit shown was designed to solve a difficult problem of cooling yoghurt without damaging this sensitive product.  Product travels through the shell in this unit which will be mounted vertically to suit the particular installation requirements.  Incorporating a removable tube bundle this product has a low pressure drop.
