Product Facts
Sentinel X400 Concentrate
System Restorer for Hydronic Heating Systems
Features & Benefits
• Effectively removes radiator sludge
• Helps restore circulation
• Restores system effectiveness
• Suitable for all metals including aluminum
• Easy to handle
• Neutral pH - no neutralisation procedure is
needed
• Manufactured under a quality system
conforming to ISO9001
Application
Sentinel X400 Concentrate has been formulated for
the effective cleaning of existing hydronic heating
systems where there is a significant amount of
corrosion debris.
Sentinel X400 Concentrate disperses old corrosion
products. It is ideal for use where a new boiler or
pump is to be fitted to an existing system, or where
radiators have cold areas or are partly blocked due to
sludge build up.
Sentinel X400 Concentrate is a non-acid formulation
which can used in all types of indirect heating
systems including those containing aluminum
components.
Dosing & Feeding
One cartridge of Sentinel X400 Concentrate is
sufficient to treat a typical residential system of 25
gallon.
For larger systems use more cartridges. To
clean an existing system, Sentinel X400 Concentrate
should be circulated, preferably at normal operating
temperature, with all valves open and the pump
turned to maximum flow for a minimum period of 2
hours or until satisfactory performance is restored.
Where systems are badly fouled, a longer period of
circulation (e.g., up to 4 weeks) is recommended, but
the product will not clear a completely blocked pipe.
There is no limit to the time for which the product can
safely be left in the system. Rapid cleaning may be
carried out if Sentinel X400 Concentrate is used in
conjunction with a power-flushing device.
Flush the system before refilling and treating with
Sentinel X100 inhibitor or Sentinel X500 inhibited
antifreeze.
The product may be added directly to the heating
system either via an air bleed valve, or via the fill loop
using the appropriate adaptor and a suitable caulk
gun.
