INTRODUCTION
ENPREP 220 EC is especially developed for use in energy conserving systems.It is designed for use at lower temperatures than conventional electrocleaners, which will result in considerablesavings in energy consumption.
ENPREP 220 EC is a multi purpose, alkaline electrocleaner for use with steel, copper and brass.
ENPREP 220 EC can be used either as a cathodic or as an anodic cleaner.
Although ENPREP 220 EC can often provide sufficient cleaning for lightly soiled work the use of a soakcleaner, preferably ENPREP 110 EC, prior to the ENPREP 220 EC is advised for heavily soiled components.
