NSF/ANSI 61 Certification

NSF/ANSI 61 addresses a set of national standards relating to water treatment. It establishes strict requirements for the control of equipment that comes in contact with potable water or products that support the production of potable water.

TIGGs large vessel CP line of liquid phase systems which include CP10K-8, CP20K-10, CP20K-12, and CP40K-12 are NSF/ANSI 61 certified and ASME code stamped.  These filtration tank systems can contain 20,000-80,000 lbs. of activated carbon with flow rates ranging up to 1,500 gpm and designed to promote even flow distribution and efficient adsorbent utilization.

Why is NSF/ANSI 61 Certification Important?

If you manufacture, sell or distribute water treatment or distribution products in North America, your products are required to comply with NSF/ANSI 61: Drinking Water System Components – Health Effects by most governmental agencies that regulate drinking water supplies. *

TIGG is the only company whose systems are completely certified to NSF Standard 61 regulations for potable drinking water.  All TIGG’s CP line of liquid phase systems and associated fittings adhere to these stringent specifications; these include the mechanical devices, pipes, fixtures, valves, gaskets, and coatings.

Compliant vs. Certified

For a system to be certified, it must be tested by a third-party based on the guidelines for the certification.  This would include product engineering and use, audits of the plant along with sample collections are completed randomly throughout the year to maintain the certification.
