Please consult an application engineer for a more specific recommendation.
Reduce inventory—single device for heat only, heat/
cool control and indicator. Fast configuration—plastic
extruder specific settings and default parameters to fit
the selected mode. The Omega CNP Series extruder
temperature controllers are an economic solution to
precision temperature control of extruders. With two
package sizes and multiple output configurations,
the controllers are suitable for twin and single screw
extruders, both for heat only die and adapter zones,
and heat/cool for barrel zones. The controllers can
also be used in an indicator only mode, allowing one
instrument to be used for all applications. With three
default parameter settings for indicator, heat and
heat/cool modes, the Omega CNP Series controllers
offers the ultimate in flexibility for the control of
industrial plastic extruders.
