FreeKeg

BENEFITS

• 75% reduction in plastic waste compared with single-use kegs in the market.
• FreeKeg is designed for maximum safety under pressure.
• The built-in overpressure valve on the liquid slide eliminates the risk of explosions.
• Inclusion of fiberglass composite material which is strong, flexible and in rare cases of failure, pressure is gradually released through small cracks.
• The valve activates even when the keg is 100% filled with liquid.
• Features a sturdy keg neck and threading that ensure optimal functionality.

Economy:

• 10% lower price compared to single-use plastic kegs.
• Competitive prices linked to the PET Keg Index.
• Exports still achieve a 10% savings in the first lifecycle.

 

✅ Step-by-Step Guide: Filling a FreeKeg (overview)

This guide shows how to fill a FreeKeg using its replaceable inner bag and compressed air. Follow each step carefully to ensure safe and proper filling.

🧰 What You’ll Need:

• A FreeKeg shell with a fresh inner bag installed
• Filling coupler (correct type for your keg: S or K-type)
• Compressed air supply with pressure gauge
• Product source (e.g., beverage tank)
• Air vent access
• Optional: bag installation tool (for bag replacement)

🛠 Before You Start: Set Up and Safety

1. Visual inspection: Make sure the keg and overpressure valve are not damaged or blocked.
2. Install new bag (if not already done):

2. • First, neutralize pressure (see Step 2).
   • Use a tool to remove the used bag and insert a new one by tightening clockwise.

3. Check max pressures:

3. • Filling pressure should not exceed 1.5 bar.
   • Never exceed 3.5 bar for dispensing.
   • Safety valve opens automatically at 8 bar.

🔄 Step 1: Neutralise Pressure (If Replacing the Bag)

1. Use a coupler without hoses.
2. Attach it to the keg’s head.
3. Press the handle down to release the pressure (you’ll hear a hissing sound).
4. Wait 5 minutes to ensure full depressurisation.

💨 Step 2: Add Counterpressure (Compressed Air)

1. Connect your compressed air source (via air gun with gauge) to the CO₂ outlet on the coupler.
2. Attach and engage the coupler.
3. Fill the keg with air until pressure reaches 1.5 bar.

This stabilizes pressure around the bag, helping avoid foaming during filling.

🍺 Step 3: Fill the Keg with Beverage

1. Connect the filling coupler to your tank.
2. Attach the coupler to the FreeKeg and open the liquid valve fully.
3. Wait ~20 seconds to allow flow to begin.
4. Slowly open the air vent to 50% on the coupler and leave for 2–5 minutes.
5. Then open the air vent on the coupler to 100% and continue filling.

✅ Stop filling when:

• The keg is full, or
• The desired weight or volume is reached.

6. Close the liquid valve.

You may need to add top pressure to the tank containing the beverage to force it into the kegs as the level drops or use a pump.

🧪 Step 4: Check for Functionality

After filling, check:

• That the keg holds pressure at 1.5 bar for at least 24 hours (recommended test).
• For leaks or damage around the valve or bag.
• That the coupler is sealed properly.

🧼 Additional Notes:

• Always use a fresh bag—never reuse.
• Store filled kegs below 35°C and upright.
• Do not shake or roll the keg, especially when filled with carbonated products.
