Meet application needs with maximum performance
Our semi-welded plate heat exchangers are optimized for industrial refrigeration applications. The semi-welded plate heat exchangers from Danfoss are designed for ammonia systems and can be used for applications such as condensers, flooded and pumped evaporators, sub-coolers, desuperheaters, superheaters, economizers and oil coolers. The product range includes the sizes SW19-SW59, with more to come, and can handle temperatures ranging from -40°F up to 248°F and pressure ranges up to 300 psi.
Features and benefits
Excellent heat transfer capabilities
Reliable design - operational safety
Easy product configuration
Comprehensive testing
Part of diversified product range for IR systems
New plate design delivers excellent heat transfer capabilities
The SW19-59 range features excellent heat transfer capabilities via improved thermal performance due to optimized plate geometry supporting high turbulent ammonia flow enabling a compact design and supporting lower charge for your refrigeration.
New gasket system improves plate pack stability
The new gasket system ensures high gasket stability and optimal plate alignment due to new gasket and gasket grove design, enabling easy and fast service and maintenance. The new design improves the sealing effect and prevents gasket-blow out. Furthermore, the risk of contamination is reduced due to the double gasket barrier that will drain potential leakages outside of the plate pack. The new gasket system is glue free for easy maintenance.
Easy maintenance and service
The new range is easy to service and maintain. Assembly of the plate heat exchanger is fast and safe thanks to fixed bolt heads and lock bushes that prevent the nut and bolt head from rotating when opening and closing the unit. The enhanced gasket system ensures easy and precise plate pack alignment, which is easy to access due to the non-corrosive nylon roller.
High quality product - fully tested
The Danfoss semi-welded plate heat exchanger design has been verified through thermal and mechanical tests. Furthermore, each semi-welded plate cassette and fully assembled plate heat exchanger are thoroughly leak tested with helium before they leave the Danfoss factory.
