Heat recovery 


Heat recovery is crucial for improving energy efficiency and reducing costs. The innovative plate pattern of the WideGap plate heat exchanger enables high heat recovery, even with high fibrous fluids. By running the plate heat exchanger product to product, heat transfer between fluids is optimized, resulting in efficient heat recovery. This process achieves a close temperature approach, enhancing heat transfer efficiency. By capturing and utilizing heat from the outgoing fluid to preheat the incoming fluid, significant energy savings can be achieved.

How it works

The versatile hygienic WideGap plate heat exchanger for fluids with large fibres and particles can be designed for various applications. The unit can be configured with asymmetrical channels allowing fluids carrying sizable particles to smoothly flow through the wide channel. By rearranging the plates into a symmetrical channel, heat recovery and substantial energy savings are enabled. Moreover, with its ingenious port design, fibres effortlessly navigate the channels without risk of clogging, enabling uninterrupted processing operations.

Technology conversion: WideGap plate heat exchangers vs shell and tube

When considering heat exchangers for food processing, the WideGap plate heat exchangers offer a versatile and cost-efficient solution compared to the traditional shell and tube design. 

  • WideGap plate heat exchangers have a smaller footprint, saving valuable floor space. This also means transport and installation costs are lower.    
  • The design is versatile enabling the capacity to be adjusted simply by adding or removing plates, all within the existing frame. 
  • Maintenance is easier since all heat transfer surfaces are easily accessible for inspection or mechanical cleaning. 
  • A specially designed plate pattern ensures a high degree of turbulence over the whole plate, which not only reduces fouling but also makes cleaning very effective.
