Hi there,

Sentinel X100 Inhibitor can be added to the system in a number of ways. For open vented systems, dose via the expansion tank during the final fill. For empty sealed systems, add to any convenient point before filling. For full sealed systems, use a Sentinel Dosing vessel to inject via the filling loop or other access point. Sentinel X100 Inhibitor is also available in Rapid-Dose aerosol and Concentrate gel formats.

Kind Regards
Sentinel Customer Service
