COMPOUND LOOP CONTROLLERS
Compound Loop
Controllers for gas chlorinators & metering pumps
PCU Process-Control Unit
The PCU Process-Control Unit is a microprocessor-based controller
specifically designed for automatic residual or compound loop control of
disinfection, dechlorination and chemical feed in
any water-treatment or industrial-process application. Typically used as a
set-point controller, the PCU provides accurate control of gas-feed equipment
as well as liquid-chemical metering-pump stroke length or variable-speed
drive applications.
· Four
different control modes
· Residual
or compound loop control
· Unique
control algorithm accounts for variable process lag
· Standard
4-20mA output and NEMA 4X enclosure
