PCDS

Potter Chemical

Delivery System

 

Patent #6,221,263 B1

  • Metered dosing of corrosion inhibiting treatment fluid.
  • Variable speed pump
  • Patented automatic operation when new water enters the system.  (6,221,236 B1)
  • Secondary containment tank prevents chemical spills.
  • Large tank for treating entire sprinkler system.
  • Low chemical level supervision
  • Digital Alarm Communicator Transmitter (DACT) included.
DESCRIPTION

The Model PCDS, Potter Chemical Delivery System, is a self-contained chemical delivery system manufactured specifically for wet pipe automatic fire sprinkler systems.  The unit is designed to pump liquid chemical into the sprinkler system upon the operation of a dedicated VSR-F or VSR-FE-2 waterflow switch installed on the system riser.  (Or common header for multi systems.)  The pump will deliver a regulated amount of chemical into the sprinkler system as make-up water enters the system.  The discharge rate of the pump is adjustable for waterflow rates between 10 to 100 GPM.  The corrosion-inhibiting chemical is contained in a polyethylene primary tank, which is mounted in a secondary containment tank.  A liquid level float switch provides notification of a low chemical condition.  A second float switch will interrupt power to the pump if the tank should run dry.  The DACT (Digital Alarm Communicator Transmitter) provides the ability for central station monitoring via phone lines if desired.  Only chemicals that have been checked for compatibility may be used.

PAAR, Potter Automatic Air Release

potter automatic air releasePAAR

Potter Automatic

Air Release

 

 

Patent Pending

  • Helps eliminate air/water interface line where corrosion often thrives.
  • Mechanical fail safe Water Shutoff Valve (Patent Pending)
  • Electrically supervised Water Shutoff Valve (Optional)
  • Visual indication of Water Shutoff Valve operation
  • Prevents damage from water spray, drips, or leaks from air vent
  • Complete unit ready to install at high points in the sprinkler system.
DESCRIPTION

The Model PAAR, Potter Automatic Air Release, must be installed at the high point of the fire sprinkler system.  The PAAR provides automatic venting of trapped air in fire sprinkler systems.  As a fire sprinkler system is filled with water, trapped air migrates to the air vent valve location and is released through the open vent.  The air vent valve will automatically close when water reaches the vent.  Discharge piping from the air vent valve is piped to a shutoff valve mounted in a water retention pan.  The pan retains small amounts of water discharged from the air vent valve during normal operation.  In case of failure of the air vent valve closing, the discharged water reaches a specified depth in the pan (approximately 1") and a water-soluble fiber element in the shutoff valve dissolves and closes the valve preventing further water discharge.  The shutoff valve has a visual indication of operation and a single se of NC contacts rated 24V AC/DC@2A for electronic supervision if desired.  The shutoff valve is a single-use device and contains no user serviceable parts.

  • Single set of NC contact rated 24V AC/DC@2A (contacts open upon activation of shutoff valve)
  • 6' Lg. wiring harness supplied for supervision of shutoff valve.

Optional Accessories

  • Supervised ball valve model BVS-1" or retrofit model RBVS for installation before the air vent valve when isolation of the vent and supervision of maintenance/service shutoff is required
  • Potter System Trouble Alarm Model PSTA for local system trouble alarm.
