Element Design and Technology

We have a wide range of profiles available, enabling us to offer the right balance of thermodynamic performance, pressure drop and ease of cleaning for any situation. These profiles can be chosen from our range (which includes the world's first commercially available dual-profile element), or we can match existing profiles that you have already.

We are the world's leader when it comes to producing enamelled elements, which offer a combination of both corrosion protection and good cleanliness when used in rigorous environments.

Our Enerjet™ system offers a powerful, highly effective response to the problems of plugging and fouling in rotary regenerative heat exchangers.

All our elements and associated technologies are manufactured in our state of the art facilities based in countries around the world.


Key Features

  • Labyrinth seals or dry gas seals flooded with buffer gas separate the compressor stages from gear case oil space and prevent any airborne oil particles from entering the process gas space.


  • Our integrally geared compressors are recently redeveloped assuring an high efficiency. Our range extends from single stage air units up to API 617 state-of-the-art eight-stage CO2 compressors.


  • ​​Chemical industries, Steel & Mining urea production, CO2, Air Separation Units.

HC Element

The Howden HC Element® design provides an aerodynamically closed profile that both promotes the penetration of sootblower jets and produces a higher thermal performance.

HCP Element

The HCP Element™ features a radically new design that combines two profiles, each optimised for its specific temperature band. This innovative arrangement significantly reduces cold-end fouling.

There are a large number of element profiles available for use in our heaters. The best element for a particular application depends on several factors and requires experience in the selection process to understand which are the most important.

In addition to the HC and HCP elements detailed above, Howden can provide a wide range of profiles from our optimised HS range. This includes Double Undulated, Corrugated Undulated, Flat Notched Crossed and Notched Flat/Undulated designs. We can also supply profiles of Rothemühle origin.

Howden elements are packed using our trademarked Surepack system, first introduced in 2005. This uses optimised and automated packing technology to ensure maximum performance and mechanical stability.
