OMEGA’s CMX Series watercirculating temperature controllers
are compact, versatile, and
completely self-contained water
heating and cooling systems. They
can be used for any application
that requires precise temperature
control of a heating and cooling water
circulation system, but are particularly
useful in the plastics industry as mold
temperature controllers. Applications
include the following:
l Injection molding machines—
thermoplastics and thermosets
l Platens and dies
l Rolls, laminating, and calendering
l Pipeline heating and tracing
l Jacketed vessels and tanks
The built-in electronic temperature
and process controller features
separate PID algorithms for heat and
cool control modes, dual display of
setpoint and process tem per a tures,
and simple configuration parameters
with alphanumeric cues. Even
though these systems are
so phis ti cat ed and state of the art,
they are still easy to use and
require very little training to
program and operate. Standard
NPT-threaded piping connections
allow for convenient hook-up to
CMX-250-4/240-NM
shown smaller than
actual size.
