Sentinel X100-RD Central Heating Inhibitor

Product Description

The SENTINEL PERFORMANCE SOLUTIONS X100-RD is a central heating inhibitor formulated to protect hydronic heating systems from corrosion, scale buildup, and sludge formation. Applied directly to the system water, it creates a protective barrier on internal metal surfaces including steel radiators, copper pipework, and cast iron heat exchangers. The X100-RD helps maintain system efficiency by keeping waterways clear and reducing the risk of premature component failure. It is intended for use by licensed HVAC technicians and qualified plumbers servicing residential and light commercial central heating systems.

The X100-RD is suited for closed-loop hydronic heating systems, including those with steel panel radiators, underfloor heating circuits, and combination boiler setups. It is appropriate for both new installations and existing systems where corrosion protection or system maintenance is required. Technicians typically dose the inhibitor during commissioning or after a system flush and refill. Sold as a single unit.

Installation Notes

Application of system inhibitors is typically performed by a licensed plumber or HVAC technician. Before dosing, confirm the system has been properly flushed and that the water circuit is closed and pressurized per manufacturer guidelines. Follow local plumbing codes and boiler manufacturer recommendations regarding inhibitor concentration and water treatment procedures. Do not mix with incompatible system chemicals without verifying compatibility first.
