BCG F Heating System Leak Sealer (Up to 20L/24h)

Description:

BACOGA BCG® F liquid sealant eliminates water loss of up to 20 litres per 24 hours in heating systems, pipelines, radiators, and under-floor heating systems filled with antifreeze liquid or brine. It can also be used in earth collectors and solar systems. BCG F forms an elastic seal at the leakage point, sealing all commonly used pipe materials (plastics, metals, press fittings, floor-heating systems). The sealing is permanent and resistant to ageing.

BCG F leak sealant is introduced into the heating circuit using a filling pump (BCG G 20 or BCG G 21J) and must remain in the system.

Note:

Proper use will not result in damage to pumps and control valves. Before using the product, we recommend thoroughly rinsing the system.

BACOGA BCG F USER INSTRUCTIONS:

1. Heating System Leaking:

   • Fill the heating system with water and purge it.

   • Open all mixer and heater valves fully.

   • Purge circulation pumps and leave them running.

   • Reduce the system water by the required quantity of BCG F sealer.

   • Shake the canister well.

   • Introduce the required quantity of BCG F, diluted, using the boiler fill and drain valve. Empty and rinse the canister to use all residual product.

   • Purge the circulation pumps again well via the control screw.

   • The heating system must remain operational for 7 hours with full circulation and heating on.

   • The actual sealing process may take 1 or several days, depending on the nature of the leakage. BCG F sealant must remain in the system.

2. Other Systems, e.g., Earth Collectors:

   • Pre-mix BCG F with water or brine and introduce it into the system after the heat exchanger.

   • This ensures the product dilutes and mixes in the plant without being pumped concentrated or pure through the heat exchanger.

3. Leaking Solar and Earth Collectors:

   • Pre-mix BCG F with system water containing glycol/brine.

   • Take 5-10 litres of system water with antifreeze liquid, then mix in the sealant until no residues are left in the canister. Stir the mixture well.

   • Introduce the mixture into the return (after the heat exchanger).

   • Run the circulation pump for 2 hours.

   • Bring the system to normal operating pressure and temperature. No temperature increase is required.

   • The sealing process can take 2-3 days. BCG F must remain in the system.

Additional Information:

• Observe the usual precautions when handling chemicals.

• Keep out of the reach of children.

• Disposal: See safety data sheet.

• Mixing ratio: 1 litre BCG F to 100 litres of heating water. An inadequate dose reduces effectiveness.

• Suitability for storage: 5 years from the date of manufacture. Protect from frost.
