TN2 Series Conditioners use a top-mounted, two-inch inlet and outlet solid brass valve with a motor-driven, time-tested, hydraulically-balanced piston, seal and spacer concept to pilot service flow not dependent on water pressure. No diaphragms to rupture or false transfer, ever. It’s clean, direct-operating, and reliable. It will give you up to 80 gpm hard water by-pass during regeneration, or you may have the optional “no hard water by-pass piston” for twin or multiple systems. The high ser- vice flow rates and simplified alternating or multiple lockout systems eliminate the need for diaphragms, solenoids, stagers, and side openings on mineral tanks. They have factory-wired electrical systems to assure easy installation. The TN2 Series offers you a choice of either mechanical or microprocessor meter demand systems, available in 1”, 1.5” or 2”, depending on the application.
