Heat Pumps for Drying: IEA HPT Project 59 Concludes with Final Webinar
Drying is one of the most energy-intensive operations across industry, with required temperatures frequently in the range of 100 to 200 degrees Celsius and moist exhaust air routinely discharged as waste. On 10 June 2026, the IEA Heat Pumping Technologies (HPT) Technology Collaboration Programme hosted the final webinar of Project...

You are interested in using a heat pump dryer in your industrial drying process, but are not sure how to proceed?
Heat pump-assisted drying systems are highly energy-efficient alternatives to conventional thermal dryers. They are therefore increasingly attractive for industrial applications. Several companies are already demonstrating its effective use. See the case studies compiled by the Annex 59 project team for the food, feed, ceramics and biomass sectors. By recovering and...
