DGF1BBAACXB Pulsafeeder Digital Glycol Feeder, 50 Gallon with Audible Alarm & Dry Contact by Quantrol

Pulsafeeder's Digital Glycol Feeder provides a consistent operating pressure in closed loop systems. This allows a controlled percentage of glycol solution to be fed from the 55 gallon tank. The Digital Glycol Feeder is available in two models; the DGF1 for single loop and the DGF2 for dual loop systems.

The control unit utilizes an 8-bit microcontroller for precise feed system control. The NEMA4X enclosure can be wired conduit or prewire for easy startup. The preplumbed assembly includes a pressure gauge, pressure switch, and pressure relief valve to prevent excessive pressure build up. A low liquid level switch with optional audible alarm prevents the gear pump from operating when the solution is low.

Each Digital Glycol Feeder is fully piped and wired with the following components:

Suction Assembly includes:

• PVC tubing and fittings
• PVC ball valve
• Clear poly bowl strainer

Discharge Assembly Includes:

• PVC pipe and fittings
• PVC ball valve
• PVC check valve
• Pressure gauge
• Brass relief valve with return to tank tubing

Controller Features

• Compact NEM4X enclosure for industrial applications
• Touch keypad user interface for gear pump operation
• LED indicators loss of pressure and low level
• HOA control of pumps and alarm to force relay OFF indefinitely or force relay ON for a period of 5 minutes
• Alarm silence feature
• Dual alarm relay outputs are factory configured for dry contact or powered
• Available in 115V or 230V
• Agency approved for US and Canada

Pump Features

• Heavy duty gear pump
• Bronze and stainless steel wetted components
• Close tolerance design allows for consistent performance
• Helical gears for quiet operation

System Features

• Economical design for competitive bid specifications
