Whether feeding caustic, acid or other conductive liquids to a process, this capable
controller does it with ease and accuracy. Compared with other concentration
controllers, the ControlGuard FCS is a breeze to program and maintain. Its optional
secondary pump and pump controls make it well suited for two point / two chemical
injection applications such as eggwash, bottle wash, can wash, and other industrial
spray wash applications. ControlGuard FCS can be operated as a probe based
dispenser or feed chemicals based, repeat cycle times or discreet signal inputs from
PLCs, motor contactors or manual push button.

INDUSTRIAL SYSTEMS

• Program/Control chemicals in millisiemens, percent concentration (total wash solution)
or Knight Units “KU’s”.

• Temperature display of wash solution (°F or °C)

• Conductivity or “Repeat Interval“ chemical feed modes

• Water tight molded plastic case with latch

• Menu driven digital programming

• Password protected menus

• Conductive or inductive probes (inductive probe never needs cleaning)

• Optional secondary pump controller

• Operates peristaltic, electric or air operated pumps

• Optional low supply beacon

• Temperature compensating inductive probe holds chemical concentrations constant at any
temperature
