About Us

Trusted to innovate. Proven to deliver.

At Solex, we are more than just a heat exchanger manufacturer. We apply proven thermal science in innovative ways to find better, more efficient solutions to challenges both known and new.

Starting out as a division of Cominco Engineering Services (CESL) in 1989, the company was divided in 1999 to become Bulkflow Technologies. Today, we are known as Solex Thermal Science  and we have been pioneering technology in the science of heating, cooling, and drying of solids, liquids and gases ever since. Our patented solutions can be found globally, with more than 1,300 projects in 50-plus countries and counting.


In 2019, we continued to solidify our expertise in thermal and bulk materials engineering by joining forces with Netherlands-based Mosman Stainless Steel, a worldwide leader in stainless steel. Made possible through a joint investment by the private equity firm Anders Invest B.V., our combined company provides customers with made-to-order solutions from an integrated producer of heat exchange technology that has more than 150 years of combined experience.

Energy transition

We’re also now using that same technology to change the landscape within the global 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.
