Howden’s Pre-engineered Air Preheaters & Gas Heaters are based on the original regenerative heater design developed in collaboration with the inventor in 1923. The design has been continually enhanced to reach our industry leading levels of thermal efficiency and performance enabling our customers’ vital processes. This underlines Howden’s vision of supporting the world’s industries with sustainable solutions. The pre-engineered product range provides operators looking to recover energy from fired equipment a highly efficient, low maintenance solution in a compact footprint. It can handle flue gas flows of under 50 tonnes per hour to around 200 tonnes per hour and recovered energy can extend to over 15MW depending on gas temperature drop. The heaters are suitable for integration into new plant development as well as replacements of alternative technologies within operational sites. All heaters are fully supported by Howden’s global pre-sales and aftermarket capabilities to ensure ease of project engineering and reliable long-term performance.
One of our strengths is our experience, we have thousands of successful installations to draw upon. Explore our reference list.

Available in both vertical and horizontal configurations, virtually every parameter can be modified or changed to suit the application and duties of the heater and the preferences of the customer.
In many industries, recuperative type heaters are used as well as regenerative. Howden’s design is a strong choice delivering substantial life time value particularly when considered against alternative technologies.
Howden has a long history of supply going back multiple decades and totalling more than 5000 heaters. Over 1000 of these are within range of our pre-engineered heaters.
