Alfa Laval has announced the launch of the TS45, its largest semi-welded plate heat exchanger to date, designed to meet growing demands for high-capacity, high-pressure heat transfer across energy transition, industrial, and energy efficiency applications.
Unveiled in Lund, Sweden in May 2026, the TS45 expands Alfa Laval’s semi-welded portfolio into duties traditionally served by shell-and-tube technologies, offering customers a path to scale up heat transfer performance while maintaining a compact footprint, high energy efficiency, and full serviceability.
Madeleine Gilborne, president of Gasketed Plate Heat Exchangers at Alfa Laval, described the launch as a step change for the technology. “With TS45, we are redefining what semi-welded plate heat exchangers can deliver at scale,” she said. “It allows our customers to improve efficiency and decarbonise large industrial processes, while maintaining the flexibility and serviceability they expect.”
The TS45 combines Alfa Laval’s proven semi-welded cassette technology with an extra-large plate format, delivering high design pressure, significantly increased capacity, and a reduced installation footprint. The result is a solution that helps customers lower operating costs while boosting overall efficiency.
The exchanger is engineered for demanding applications including industrial heat pumps, energy storage, carbon capture, and sulphuric acid production — sectors where robustness, reliability, and efficiency are critical. By pushing semi-welded performance into territory previously dominated by shell-and-tube equipment, Alfa Laval is positioning the TS45 as a competitive option for large-scale industrial decarbonisation projects.
The TS45 is available from Q2 2026.
