Introducing SWEP B4TS – the newest all-stainless brazed plate heat exchanger from SWEP

Designed especially for electronics, semiconductor, and next-generation refrigerant applications. The SWEP B4TS is frameless, compact, and engineered to withstand both the high pressure demanded by R744 (refrigerant-grade CO₂) and the corrosive nature of deionized water.

Exceptional performance, durability, and environmental sustainability make the SWEP B4TS a versatile solution for advanced cooling. Its frameless design delivers superior heat-transfer efficiency per kilogram, while minimizing the use of materials. It is ideal as an evaporator, condenser, or gas cooler in applications where cleanliness, pressure resistance, and environmental compliance are all essential.

Corrosion-resistant design

SWEP B4TS is a powerful addition to the All-Stainless range, which offers corrosion-resistant performance in demanding environments. Like all SWEP All-Stainless^TM heat exchangers, SWEP B4TS is brazed using a copper-free filler material that closely matches the composition of the stainless steel plates. This makes it ideal for chiller applications in the electronics and semiconductor industries, which rely on highly corrosive deionized (DI) or ultrapure water as a coolant.

The future of advanced cooling

European Union F-gas regulations and the AIM Act in the U.S. are accelerating the phase-out of high-GWP refrigerants and PFAS-based solutions. As a result, natural refrigerants, such as CO₂, which has a GWP of 1, are gaining momentum in the marketplace. The electronics and semiconductor industries, among others, are increasingly turning to cooling solutions that combine effectiveness with sustainability, supporting long-term environmental goals and making it easy to comply with current and future regulations.

The SWEP All-Stainless B4TS is more than a new product – it is a strategic choice to support the transition from harmful refrigerants to the low-GWP refrigerants of the future. By combining DI and ultrapure water compatibility, CO₂ readiness, and exceptional compactness, SWEP is helping chiller manufacturers meet today’s requirements while preparing for tomorrow’s regulatory demands.
