WITH MINI REGULATOR
MRDC APPLICATIONS:
1 Portable irrigation
eliminate crop wash out from
partially pressurized sprinklers
during system start up and shut
down.
2 Overhead cooling of apples
and other crops, to prevent
drainage of the system in between
frequent on and off cycles of the
irrigation system.
3 Green house irrigation sys-
tems, where sprinkler dripping or
drainage after shut down cannot
be tolerated.
4 Systems where pressure gains
or losses are high due to
uneven topography or high
friction loss in pipes, to ensure
high uniformity and even flow of
all sprinklers in a system.
