-Plate&Ring-® Heat Exchanger

Vahterus -Plate&Ring-® (PRHE) is a new generation heat exchanger. Using a plate pack of fully welded circular plates, within a shell (pressure vessel), PRHE offers high heat transfer capacity for various applications including gas heating & cooling, exhaust gas heat recovery and steam condensers. The special ring-plate, fully welded with no gaskets or brazing, provides a compact, efficient and durable solution, for many applications that traditionally employ different types of tubular heat exchangers.

Applications

• Gas heating/ cooling
• Exhaust gas heat recovery /economizer
• Condensers
• Preheaters
• High viscosity liquid/ liquid applications

Vahterus PRHE combines the benefits of Plate & Frame and Shell & Tube heat exchangers. PRHE can either be described as a fully welded, high integrity plate heat exchanger, with no gaskets; or a generic alternative to Shell & Tube, approx. 25% of the footprint, displaying both space and weight benefits.

Benefits of PRHE

• No Gaskets or Brazing
• High Integrity / Total Containment
• Strong and Safe Construction
• Unique Protection and Resistance
   to Thermal and Pressure Cycling
• Thermally Efficient
• Compact and Low Weight
• Flexible Construction
• Proven, Reliable Technology
• Low Fouling
• Minimal Maintenance Requirement
• Close Approach Temperatures
