SWEP Launches All-Stainless B4TS Heat Exchanger

30 January 2026 | NEWS

New product supports cooling needs in electronics and semiconductor fabs

 SWEP, part of Dover (NYSE: DOV) and a world-leading supplier of brazed plate heat exchangers (BPHEs), announced the launch of its SWEP All-Stainless B4TS product designed for the electronics and semiconductor industries.

The SWEP B4TS is frameless and compact and designed for use with R744 (refrigerant grade CO2) built for handling high-pressured applications. This innovation supports environmentally sustainable refrigeration solutions.

Manufacturers of chillers for the electronics and semiconductor industries frequently utilize deionized water as a coolant. The SWEP All-Stainless B4TS is engineered to endure the corrosive nature of deionized water and offers an option to incorporate the natural refrigerant CO2 in the second circuit. Its innovative frameless design delivers superior heat transfer efficiency per kilogram while minimizing material use. Together, these features ensure high performance, durability and environmental sustainability, making the B4TS a versatile solution for advanced cooling applications, including evaporators, condensers or gas coolers.

"Natural refrigerants are expanding across all applications and markets SWEP serves as customers continue to seek compliant solutions," said Joakim Palmberg, SWEP Marketing Director. "SWEP is dedicated to providing state-of-the-art products that support the rapid evolution of the electronics and semiconductor industries, playing a central role in enabling customers to transition to environmentally responsible technologies. The SWEP B4TS clearly exemplifies this commitment."

SWEP is leading the transition toward sustainable energy use in heat transfer, continuously innovating to produce more efficient solutions that require less energy, material, and space. This includes the ongoing development of new products designed for natural and low-GWP refrigerants.
