Heaters Aftermarket Services

Optimising operation and extending equipment life time

With products whose operating life can be anything up to 40 years and beyond, we believe in building lasting relationships with our customers. It is our duty to offer only the very highest standards of service, from initial installation of plant and equipment through routine maintenance to subsequent refurbishment and enhancements, to meet environmental legislation and operational changes.
As the OEM of Howden heaters and Rothemühle heaters and ESPs, we have a deep understanding of the equipment to guide design changes and provide original or improved parts. Using specialised software, we can model all rotary regenerative heat exchangers and electrostatic precipitators to accurately predict the operational and cost advantages of our proposals. Environmental considerations and energy costs make it more important than ever to ensure equipment is working at optimised levels.

Plant enhancement

Our research and development coupled with long standing links with specialist suppliers, enables us to improve the performance of our own brands, such as Howden and Rothemühle, as well as that of equipment supplied by other manufacturers.
We have a number of methods with which we can improve your Rotary Heat Exchangers that will result in savings including addressing leakage issues by improving the sealing system and/or increasing thermal performance utilising a different element profile.
For Rothemühle ESPs we can improve performance through a range of upgrade options as well as full refurbishment of the ESP with new internals.


Maintenance and spare parts

Howden has the experience and expertise to design, install and carry out planned routine maintenance programmes leaving our clients free to focus on their core activities while minimising disruption.
We regard the supply of parts as a core activity, and we treat it with the same attention that we bring to new installations.



We have unique global experience with Rotary Heat technologies and ESPs based on Howden and Rothermühle brands. Where we supply equipment, whether it is replacement of internals or a new custom designed unit, we can carry out all of the installation and associated works as a full turnkey service or as required. 
Our service technicians and field engineers can supervise the installation and commissioning to ensure the equipment is safely and properly installed and commissioned. Their experience is invaluable in eliminating problems and minimising time and cost.
