We are the market leader and developer of high-efficiency, indirect heat exchange technology for the heating, cooling and drying of free-flowing granular materials such as solid granules, pellets, beans, seeds and particles. With operations in Canada, The Netherlands and the UK, our company has installed more than 1,200 advanced heat exchangers in more than 50 countries worldwide over the past 30 years in applications such as fertilizer, oilseeds and industrial materials such as minerals/sands, chemicals and polymers. In recent years, our company has expanded into the energy-transition sector through key collaborations in low-carbon applications such as industrial waste heat recovery and reuse, renewable energy storage, carbon capture and electrification. In 2023, Solex acquired Econotherm Ltd, leading UK-based manufacturer of heat pipe heat exchangers used in diverse, difficult-to-recover waste heat applications such as recuperators, economizers, pre-heaters, steam generators and condensers.
