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. Easy access to the plate pack with the non-corrosive nylon roller that makes it easy to slide the follower along the carrying bar. assembly of the plate heat exchanger is fast and safe thanks to fixed bolt heads and lock bushes which 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.

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.

Availability

Our new line of Semi-welded plate heat exchangers is available now in Europe, Middle East and Africa. It will be available in the rest of the world during 2019.
