Southwest Thermal's stainless steel brazed plate heat exchangers are designed for high efficiency and durability in compact packages. Made from premium stainless steel with copper or nickel brazing, they resist corrosion and provide reliable performance in applications like fluid-to-fluid heat transfer, refrigeration, evaporators, condensers, heat pumps, hydronics, and CO2 systems. Their gasket-free design ensures low maintenance and leak-proof operation, with ASME certification available for industry compliance.
Stainless steel brazed plate heat exchangers are used in a wide range of processes, including fluid-to-fluid heat transfer, refrigeration systems, evaporators, condensers, heat pumps, hydronic heating and cooling, and CO2-based applications like supercritical CO2 cycles or refrigeration. Their compact design and high efficiency make them suitable for both industrial and residential settings.
Our brazed plate heat exchangers are made from high-quality 316L stainless steel, with options for copper or nickel brazing to suit various fluid compatibilities. They are available in sizes ranging from small units for residential HVAC to large industrial models with capacities up to several hundred tons. These exchangers operate at pressures up to 650 psi and temperatures from -320°F to 450°F, with corrosion-resistant options like titanium for aggressive media such as CO2 or refrigerants.
The corrugated plate design maximizes heat transfer efficiency by creating turbulent flow, allowing for close approach temperatures. The brazed construction eliminates gaskets, reducing maintenance and ensuring long-term reliability in applications like evaporators, condensers, and hydronic systems. These units are fully sealed, leak-proof, and designed for easy integration into existing systems.
While brazed plate heat exchangers excel in clean fluid applications, we also offer shell-and-tube, plate-and-frame, and tube-in-tube designs for specialized needs, such as handling viscous fluids or high-pressure environments. Our brazed plate models remain the go-to choice for compact, high-efficiency solutions in refrigeration, heat pumps, and CO2 processes.
