ETS is a series of electrically operated expansion valves for precise liquid injection in evaporators for air conditioning and refrigeration applications. The valve piston and linear positioning design is fully balanced, providing bi-flow feature as well as solenoid tight shut-off function in both flow directions. The ETS needs a current or voltage driver as partner to be operated. EKC316A, 312 and EKD316 are examples of Danfoss controllers with drivers matching the ETS needs. All HVAC/R systems can benefit from the most comprehensive series of electronic expansion valves on the market. The Danfoss portfolio makes it possible to keep up with increasing environmental concerns and tighter CO2 emission regulations, while enabling significant energy savings and cost reductions.
