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
