TECHNICAL INSTRUCTION DOCUMENT
X100 - Inhibitor
APPLICATION:
To inhibit corrosion, scale, boiler noise and hydrogen gassing, add Sentinel X100. For
best results, systems should be cleaned and flushed using a suitable Sentinel cleaning product – see the
AERCO website for guidance (www.aerco.com). If the system is already noisy due to deposits in the heat
exchanger, Sentinel X200 should be added together with Sentinel X100. Sentinel X100 is suitable for use
with all commonly encountered metals and alloys, including aluminum.
DOSE RATE:
Sentinel X100 should be dosed at 1% of system volume, i.e., 1 Quart per 25 Gallons of
system water. For larger systems, additional X100 will be required. Overdosing does not present a
problem. Please note: Where a thermal storage appliance is fitted, allowance must be made for the
increased volume of primary water. The concentration may be checked with a Sentinel Test Kit or a
conductivity meter.
DOSING INSTRUCTIONS
: Open vented Systems: Dose via the expansion header tank, via a by-pass
feeder or use a dosing bottle. Sealed Systems: If the system is empty, add to any convenient point before
filling. If full, use a dosing bottle to inject via the filling loop or other access point.
LEAVE IN SYSTEM DO NOT ADD TO PRIMATIC SYSTEMS
X200 – Noise Reducer
APPLICATION:
Where a boiler is kettling add Sentinel X200 and leave in system. The time taken for the
noise to reduce/be eliminated will depend on the nature of the problem. Several weeks under normal
operating conditions may be needed. To inhibit corrosion, scale and hydrogen gassing, add together with
Sentinel X100 Inhibitor or Sentinel X500 Inhibited Antifreeze. Sentinel X200 is suitable for use with all
commonly encountered metals and alloys, including aluminum. Please note: Boiler noise can also be
caused by sludge (eg iron oxide corrosion debris), in which case, the system should be cleaned and
flushed using a suitable Sentinel cleaning product – see the AERCO website for guidance
(www.aerco.com) Many noise problems are caused by system design or mechanical faults. It is important
to check for these before seeking a chemical solution.
DOSE RATE:
Sentinel X200 should be dosed at 1% of system volume, i.e., 1 Quart per 25 Gallons of
system water. For larger systems, additional X200 will be required. Higher doses do not present a
problem and are often beneficial. Please note: Where a thermal storage appliance is fitted, allowance
must be made for the increased volume of primary water
DOSING INSTRUCTIONS
: Open vented systems: Dose via F&E cistern (sufficient draining from a low
point is required to ensure that all of the product enters the circulating part of the system), or use a dosing
bottle. Sealed systems: If the system is empty, add to any convenient point before filling. If full, use a
dosing bottle to inject via the filling loop or other access point.
LEAVE IN SYSTEM DO NOT ADD TO PRIMATIC SYSTEMS
