Superior Flow. Superior Savings. Superior Water for Commercial and Industrial Needs.

The top-mounted control minimizes the system's footprint and is constructed of a corrosion-resistant, heavy-duty plastic tested in extreme operating conditions to service all types of problem water (high chloramines, heavy iron, etc.). The CTM valve and system also carry certification for testing and passing the highest drinking water standards.
