System power flushing

Powerflushing can be used to service to existing systems or new Installations. We chemically cleanse and flush the entire system using a Magnacleanse machine (for sealed systems) or a Kamco Quantum CF90 Powerflush Machine (for older or open vented systems).

This removes all the debris and contaminants; the system will then be treated with corrosion inhibitor which will increase the reliability and overall efficiency of the system.
