Cleaner for removing stubborn deposits for systems older than 6 months

A powerful, highly-active cleaner, Sentinel Deposit Remover is ideal for removing stubborn deposits from older indirect central heating systems. It has a unique composition which allows it to break down and remove stubborn scale and corrosion deposits under less acidic conditions than corrosive mineral acid based products.

Key features

  • Heavy duty organic acid cleaner
  • Suitable for central heating systems and potable water systems
  • Powerful magnetite and limescale removal
  • Removes the toughest deposits
  • Suitable for use with all commonly encountered metals and alloys

Available sizes

5L liquid DEP-4X5L-GB

Sentinel Deposit Remover restores a more even heat distribution to systems with stubborn scale and corrosion deposits. Once these deposits have been shifted, the effectiveness of heat transfer in the boiler and radiators is restored, ensuring that the system then operates at maximum effectiveness. Sentinel Deposit remover is suitable for use with all commonly encountered metals and alloys. Aluminium may be cleaned, but care must be taken to limit the cleaning time to a maximum of 2 hours.

5 litres of Sentinel Deposit Remover is sufficient to clean a typical domestic heating system of up to 10 radiators. For larger systems, 10 litres should be used. For faster cleaning, or with heavily fouled systems, a typical system should also be cleaned with 10 litres. The main system pump is suitable for circulation throughout the entire system.

The cleaning process can be accelerated when the Sentinel Deposit Remover solution is heated and in constant circulation, but the temperature must not exceed 60°C.

In accordance with BS7593, more rapid and effective cleaning will result if Sentinel Deposit Remover is used in conjunction with a power flushing device.

After cleaning, the system should be drained and flushed until the water runs clear. Check that the pH or conductivity of the flush water matches that of the mains water.

Powerflushing: Follow the instructions supplied with the powerflushing machine.

Open Systems: Dose via F&E cistern, via a by-pass feeder or use a Sentinel Dosing Vessel.

Sealed Systems: If the system is empty, add to any convenient point before filling. If full, use a Sentinel Dosing Vessel to inject via the filling loop or other access point.
