    What Is Sentinel X400 High Performance Cleaner?

    Sentinel X400 High Performance Cleaner is a liquid system cleaner formulated for use in older or contaminated heating systems. It targets sludge, corrosion products, and deposits that build up during normal operation. Consequently, it improves water flow and heat distribution.

    The cleaner works at normal system temperatures. Therefore, installers can use it during routine servicing and maintenance.


    Why Deep System Cleaning Is Important

    Sludge and debris restrict water flow and reduce radiator output. As contamination increases, boilers work harder and energy consumption rises. As a result, component wear accelerates.

    By using Sentinel X400 High Performance Cleaner, installers remove harmful deposits. Furthermore, clean systems allow inhibitors to work effectively.


    How Sentinel X400 High Performance Cleaner Works

    Once added, Sentinel X400 circulates through the heating system. It loosens and suspends sludge and debris from internal surfaces. Therefore, contaminants flush out easily during draining.

    After cleaning, the system becomes ready for inhibitor dosing. Consequently, long-term protection improves.


    Key Features of Sentinel X400

     X400 High Performance Cleaner delivers strong cleaning action without damaging system components. It restores circulation and improves heat transfer efficiency. As a result, system performance improves noticeably.

    The formulation remains compatible with modern and traditional heating systems. In addition, it integrates easily into professional cleaning routines.


    Applications and Suitable Uses

    Existing and Contaminated Heating Systems

    Sentinel X400 suits older systems with reduced performance. It helps restore circulation and radiator heat output. Therefore, it supports effective system recovery.

    Sludge and Circulation Problems

    The cleaner addresses cold spots, noisy operation, and poor circulation. As a result, heating systems operate more smoothly and efficiently.


    Benefits for Installers and Homeowners

    Sentinel X400 helps installers resolve performance issues efficiently. It reduces repeat visits caused by sludge-related faults. Consequently, service quality improves.

    Homeowners benefit from improved comfort, quieter operation, and reduced energy costs. Furthermore, clean systems last longer.
