POLYBLOC

Maximum longevity and maximum efficiency – nowhere are the demands on a heat exchanger higher than in industry.

Stephan Wälti, CEO New Wälti AG, Eschlikon – CH

Industrial Heat Exchangers

A heat exchanger in industry is literally exposed to a bad atmosphere: paints, heat, acids, exhaust gases, brine or humidity put material and processing to the test around the clock.

Polybloc plate heat exchangers meet these requirements with the best quality – for all industrial applications. Worked with the highest precision and quality. For maximum durability, efficiency and energy savings.

Material

Heat exchangers made of coated aluminium, plastic or stainless steel are used for particularly corrosive pollutants. Stainless steel is the perfect material in areas where high temperatures exist on top of that. In this way, savings can be achieved in energy recovery from process heat, which very quickly amortise the investment.

For applications with special requirements to the tightness as well as temperatures over 600 C° the stainless steel versions are welded in the Microplasma procedure.

The Polybloc advantages at a glance
  • Optimal Efficiency

    The wide range of different materials, dimensions and plate spacings enables optimised solutions in terms of efficiency and pressure drop.

  • Maximum Heat Resistance

    Various materials permit temperatures of 600 °C. The gas-tight welded stainless steel heat exchanger is used above 800 °C.

  • Simple Installation

    Optionally suitable for installation in the ventilation unit or with frame construction for direct connection to the ducts.

  • Officially Certified

    Performance and hygiene are regularly certified by neutral institutions.

  • Different Materials

    Plastics are used for acids, stainless steel at high temperatures and epoxy-coated aluminium for slightly corrosive applications.

  • Minimum Maintenance Effort

    Easy to clean, no wearing parts.

  • High Differential Pressure Resistance

    The corrugated layers guarantee a differential pressure resistance of over 10,000 Pa for aluminium and up to 30,000 Pa for gas-tight welded stainless steel exchangers.
