The new Danfoss D55 is an excellent route to increased savings. With a robust and resource-ecient design, the D55 is designed to operate eciently
year after year in a whole range of applications. The innovative D55 channel plate pattern makes it the best heat exchanger on the market,signicantly
reducing energy consumption and lowering CO2 emissions. The D55 has a capacity of 10-65 kW and is suitable for evaporators, condensers
and one-phase applications. Thanks to the two-in-one connection it is always easier to install. The D55 is the natural choice for any application.
• Standard- and high-pressure designs make it the ideal solution for any application or refrigerant
• Two-in-one connection for easy installation
• With innovative micro plate channel plate pattern for higher heat transfer to minimize weight and refrigerant charge
A D55 heat exchanger is always easier to use. Every product is delivered with Danfoss two-in-one connections, which allow both threading
and soldering. The universal soldering connections are suitable for both customary/imperial and metric piping.
