TNT Series Conditioners use a flanged top-mounted or optional side-mounted adapter, three-inch NPT inlet and outlet solid brass control valve with a motor-driven, time-tested, hydraulically-balanced piston with a seal and spacer concept to pilot service flow not dependent on water pressure. No diaphragms to rupture or false transfer. It will provide up to 170 gpm hard water by-pass during regeneration, or you may have the optional “no hard water by-pass piston” for twin or multiple systems. These high service flow rates, the simplified alternating and multiple lockout systems, eliminate the need for diaphragms, solenoids and stagers. The five cycle TNT controller is available with either downflow (co-current) or upflow (counter-current) brining, with easy adjustable cycle times. The TNT Series offers you a choice of mechanical or microprocessor controlled meter demand systems, with two-inch or three-inch meter turbines. All systems are factory-wired and tested electrically to assure easy installation and correct operation.
