New Danfoss dual voltage/dual frequency solenoid coils deliver flexibility and convenience

Thursday, June 6, 2019


Danfoss, a leading global supplier of solenoid valves for refrigeration and air conditioning applications, is pleased to introduce a pair of new dual voltage/dual frequency solenoid valve coils for North America: the BT with junction box and the BU with conduit boss.


The new BT and BU coils are compatible with Danfoss' line of robust EVR refrigeration duty solenoid valves. The new coils extend the Danfoss lineup beyond the existing offerings of extensive single voltage coils. Commonly used in walk-in coolers, freezers, and food retail display cases, they are also easily applied in air conditioning applications.

With these new UL-certified coils, OEMs can provide greater flexibility to customers, allowing orders to be placed when the field operating voltage and frequency are unknown. Contractors can reduce their on-hand stock by carrying just one coil design instead of multiple coils.

Each coil can operate at one of four voltage/frequency combinations: 110V/50Hz, 110–120V/60Hz, 230V/50Hz, or 208–240Hz. 

The BT and BU coils complement much of Danfoss’ extensive refrigeration components and system solutions, such as thermostatic and electronic expansion valves, distributors, electronic temperature controls and condensing units among others to enable compliance with regulations and for saving on installation and maintenance.

These coils are also compatible with the Danfoss Magnetic Tool app, which can turn any Android and iOS device into a precise magnetic field detector.
