Genetron ST-20 Flush for Refrigeration and Air Conditioning Systems

With the phase-out of R11, common service prac- tice has been to purge systems with nitrogen and rely on filter driers to clean the system instead of flushing. Unfortunately,filter driers have limited acid removal capacity and recommended procedures such as acid testing and additional filter changes are not always followed. Additionally,contaminants downstream of the filter can cause component damage or blockage before filtration has sufficient cycles to remove the contaminants.

Genetron ST-20 Flush uses patented technology to provide excellent cleaning of refrigerant and A/C systems in a very efficient and cost effective manner.A carefully selected boiling point assures the solvent is easily removed from the system. Genetron ST-20 Flush is effective for use on all HCFC and HFC systems and is compatible with current materials of construction including common seals and gasket materials.
