Dover’s SWEP unit has unveiled the All-Stainless B4TS brazed plate heat exchanger tailored for electronics and semiconductor cooling, marking the company’s first frameless, high-pressure solution optimized for R744 (refrigerant-grade CO₂). Engineered to withstand deionized water corrosion and deliver up to 25% higher heat transfer efficiency per kilogram compared with traditional plate designs, the B4TS expands SWEP’s addressable market into advanced chiller applications such as evaporators, condensers and gas coolers. With over 1,100 employees across five production sites and SWEP’s technology already integrated into millions of systems worldwide, the B4TS launch positions Dover to capture further share in a semiconductor equipment market projected to grow at a mid‐single-digit rate annually through 2030.

The introduction of the B4TS aligns with Dover’s Climate & Sustainability Technologies segment strategy to lead in low-GWP refrigerant solutions. As global regulations tighten on high-GWP fluids, the natural CO₂-based system addresses an estimated $2 billion annual opportunity in sustainable refrigeration equipment. Dover, which reported over $7 billion in consolidated revenue last fiscal year and employs roughly 24,000 staff globally, expects the B4TS to contribute incremental segment revenue beginning in the current quarter and to support margin expansion by leveraging SWEP’s lean material use and compact design to reduce production costs by an estimated 10% per unit.
