Pulsafeeder Digital Glycol Feeder, Single-Loop, Prewired, 1.5 GPM

Pulsafeeder Digital Glycol Feeder, Single-Loop, Prewired, 1.5 GPM

The Pulsafeeder DGF1BBXACXB is a prewired, fully assembled single-loop Digital Glycol Feeder designed to maintain consistent operating pressure in closed hydronic systems. The system automatically feeds glycol solution from a 55-gallon tank to compensate for system losses, ensuring stable loop performance. A NEMA 4X control enclosure with an 8-bit microcontroller provides precise pump control, LED status indicators, HOA functionality, and an audible alarm for local notification. This configuration includes no dry-contact alarm output, making it suitable for installations where external monitoring is not required. The 1.50 GPM gear pump and standard pressure switch deliver reliable, long-term operation across a wide range of closed-loop applications.
