DIGITAL MINI FEEDER 19USG

🧰 What it is

It’s an automatic hydronic system fill/pressure maintenance unit that keeps closed-loop boiler or radiant heating systems properly pressurized.

⚙️ What it does

The DMF-300 automatically:

• Maintains system pressure in hydronic heating loops
• Adds glycol/water mix when pressure drops
• Monitors pressure digitally
• Alerts when there are faults (low level, high pressure, leaks)

🔧 Key features

• Tank capacity: ~17–19 gallons (64–71 L)
• Pressure range: 0–45 PSI adjustable digital control
• Built-in diaphragm pump
• Digital display with alarms
• Dry-run protection (pump won’t burn out)
• Fill/mixing tank for water or glycol solution
• Leak detection and alarm contacts

🏠 Where it’s used

• Hydronic boiler systems
• Radiant floor heating
• Large residential heating systems
• Commercial heating loops
• Glycol (freeze-protected) systems

🧠 Simple explanation

It’s basically a smart automatic “pressure refill station” for boiler systems—it keeps your heating loop topped off so you don’t lose heat or damage equipment from low pressure.

⚠️ Why it matters

Without a unit like this, hydronic systems can:

• Lose pressure over time
• Shut down boilers
• Develop air pockets or circulation issues
