SONDEX®
Fishbone plates

high thermal performance

Our SONDEX® Fishbone plate pattern technology is used in the majority of our plate heat exchangers. The pattern is designed for high thermal performance while using the allowed pressure drop in the most efficient manner. Fishbone plate patterns are available with different pressing depths, pattern pitch and angles with each individual pattern optimized for a certain duty.

“Years of experience have inspired innovative upgrades to create the ultimate in Fishbone plate design. The tried-and-true Fishbone plate pattern is featured in most of our SONDEX® plate heat exchangers.”

What does that mean for you?

Engineered to maximize turbulence, even at low flow rates, this pattern achieves unparalleled heat transfer. The pattern has proved its effectiveness through rigorous testing and is the default choice for plate heat exchangers.

Variants of the Fishbone pattern are designed to create different levels of turbulence, use a different pressure drop, and meet different thermal requirements. Each variant fills a particular niche, or is aimed at a certain type of duty. This flexibility allows us to optimally cover all your heat transfer needs, no matter the application.

Special features include a reinforced hanging system for better suspension, an optimized distribution area that prevents stagnant zones, a maximized heat transmission area for high performance, and the unique SONDEX® Alignment System that ensures proper plate pack stability and keeps the individual plates firmly in place in the assembled heat exchanger.

Features and benefits

  • Maximized heat transmission area, fine-tuned for each application, reduces the total number of plates needed for optimal performance. High efficiency lets you dial up performance and dial down your energy consumption.
  • Designed to ensure an even distribution of media across the entire plate and prevent stagnant zones, resulting in the best possible use of the pressure drop.
  • Unique gasket system that prevents misalignment of the plate pack and allows for easy assembly. The specially designed gasket groove preserves gasket elasticity and increases its lifetime.
