Victrex APTIVT Film Replaces Metal In Heat Exchanger

In this design, APTIV film is spiral bound with high temperature-resistant glue to provide the right mixture of high temperature performance and chemical resistance. It provides an effective barrier against many liquids and gases; is lightweight, halogen-free, and withstands lead-free soldering process temperatures. It is also RoHS compliant and can be used to manufacture products compliant with the same directive.

Environmentally friendly and 100% recyclable, Makatec heat exchangers achieve heat transfer coefficients in the range of 1 kW/m2K (176 BTU/hft2°F) comparable to conventional plate heat exchangers (PHE). The unique spiral design allows volume specific heat exchange areas up to 1000 m2/m2 (305 ft2/ft2). The smooth surfaces of APTIV film significantly reduce the risk of residue build-up inside the heat exchanger, thus minimizing the danger of microbial contamination. The heat exchangers are well suited for use in potable water systems and in the food sector, as well as in pharmaceutical industry and biotechnology applications.

By using APTIV film to replace metal, Makatec has been able to achieve overall systems cost reduction. The exchanger's simple design allows for low cost assembly even for unique specifications. It costs significantly less than a stainless steel exchanger and, when compared to conventional plate heat exchangers (PHE), operational costs are reduced due to the minimal pressure drop required by the pump engine. Maintenance and service costs are also reduced due to the corrosion resistance of the APTIV film.

APTIV film offers the performance properties performance of VICTREX® PEEK™ polymer, including: high temperature capability, excellent chemical resistance, exceptional durability and scratch resistance, outstanding radiation resistance, superior mechanical properties, and excellent barrier and electrical properties, all combined with the ease of processing inherent in a thermoplastic material, in a film format to meet these challenges. Its versatility and high performance make it the material of choice where the increasing demand for lighter weight, durable, lower cost and eco-friendly application designs need to be met.
