technology

New plate design by Danfoss
Our Danfoss engineers have enhanced the way heat exchanger plates are designed with the introduction of the new D-plate series. Drawing on years of experience within heat transfer technology and deep application knowledge, we have made significant upgrades to the traditional Fishbone plates to truly redefine the way we think of heat exchanger plates.

Maximizing both performance and product lifetime, the D-plate series is a milestone in innovation and moves plate heat exchanger technology into a bright new era of advanced, yet simple solutions.

 

Experience D-power

Someone once said that all gasketed plate heat exchangers are not the same and that you should always look at the features on offer. This is a belief that we share at Danfoss, and why we never settle for mediocre solutions. Just because something works doesn’t mean that it can’t be improved, which is why we never stop innovating: to bring you the best solution possible.

 

Powerful performance
We have increased the thermal performance of our plates by up to 10% compared to the usual plate design.

 

 

The strongest plate to date
Up to 25% thinner plates with D-plate technology compared to normal plates in the same pressure range. Diagonal reinforcements made from a cost-effective, durable glass reinforced composite ensure that D-plates are very strong.

 

 

Highly intuitive hanging system
Our new hanging system uses a component made from a cost-effective, durable glass reinforced composite that makes servicing the plate pack highly intuitive and easy.

 

Revolutionary D-LockTM
The patented D-LockTM gasket system is easy to attach. It snaps the gasket into the D-LockTM sockets and keeps it firmly in place. The system is designed so that no part of the gasket is exposed to UV-light, thereby extending its lifetime.

 

 

Perfect plate alignment with corner locks
Perfect plate alignment with our new corner locking system. The plate corners fit together to stabilize the plate pack and eliminate the risk of snaking.

 

D-plate technology

“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.”

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.

 

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.
