Non-Metal Spiral Heat Exchanger Technology

Building on many years of experience in developing and manufacturing spiral-wound membrane modules for diffusion dialysis, Spiraltec has developed an innovative non-metal spiral heat exchanger for applications requiring high chemical resistance, reliable heat transfer, and long-term operational stability.

Manufactured from polypropylene (PP) components, including PP film and PP spacers, our Spiral Heat Exchanger provides excellent resistance to acids, bases, and saline solutions while offering a lightweight and cost-effective alternative to conventional metallic heat exchangers.

The unique spiral wound design with counter-current flow channels enables efficient heat transfer, uniform flow distribution, and compact construction. This allows the heat exchanger to meet a wide range of requirements in terms of flow rates, thermal performance, and chemical compatibility.

Overview Fields of application

Our Heat Exchanger is designed for industrial applications where corrosion resistance, chemical compatibility, and efficient thermal management are essential.

Electrochemical Processes

Temperature control of electrolyte solutions, such as electroplating baths, where reliable heat management and chemical resistance are critical. Combined with Spiraltec diffusion dialysis technology and conventional cooling systems, the heat exchanger enables cost-effective bath maintenance and improved process stability.

WHY COUNTER-CURRENT FLOW?

Our Heat Exchanger uses a counter-current flow configuration, where the hot and cold fluids flow in opposite directions. This arrangement maintains a high temperature difference between the two fluids along the entire heat exchanger length, resulting in more efficient heat transfer compared with parallel-flow designs.

Benefits of Counter-Current Flow:

  • Higher thermal efficiency
  • Improved heat recovery capability
  • Reduced energy consumption
  • More uniform outlet temperatures
  • Compact and high-performance design
  • Improved overall process efficiency
