The range of electronic expansion valves are
based on many years of experience.
ETS 6 secure reliability and provide a precise
solutions for ex pansion and flow control
in a wide range of refrigeration and air
conditioning systems.
Compact and lightweight. The current range
is available with a wide capacity range, and
can be used with all common fluorinated
refrigerants. Bi-flow operation is also possible
for heat pump systems.
The valve operation is by means of a uni-polar
motor, which can be controlled by a number
of controllers from Danfoss or third party
vendors.
With an EKD 316 and EIM 336 (current drivers)
ａnd an AKS sensor, an accuracy better than
+/- K can be obtained.
Please contact Danfoss for more details.
