Pulsafeeder, Cooling Tower Controller, Series MC9300/9500

Pulsafeeder, Cooling Tower Controller, Series MC9300/9500The MC9300/9500 Series Controllers are a microprocessor based controller of recirculating cooling water systems. The controllers provide the ability to accurately control the level of dissolved solids based on µS/cm, and depending on model selection, control conductivity, pH, ORP and cycles of concentration based on the conductivity of the system make-up water.

The controllers feature:

  • Up to four user selectable timers that will operate in any one of seven modes.

  • A manually entered data collection field with ten user defined fields and units, stored in the controller's history (downloadable with PULSAworks software).

  • Four single-point drum level inputs (9500 only)

  • Multiple security levels and lockable input window.

  • One or two point calibration
