Hellenbrand Means
Quality and Reliability
Since 1967, Hellenbrand Water Conditioners, Inc. has provided water solutions to the water treatment industry in the
U.S. and around the world. We have developed a complete line of high quality products. An excellent example of this,
is the Hellenbrand TNT Series Conditioners.
TNT Series Conditioners use a anged 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 ow 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 ow rates, the simplied alternating and multiple lockout systems, eliminate the
need for diaphragms, solenoids and stagers. The ve cycle TNT controller is available with either downow (co-current)
or upow (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.

TNT Series Control Valve -Three Inch Inlet/Outlet
1. Stainless Steel Backplate will not rust or corrode.
2. Factory provided Drain Line Flow Control maintains
accurate backwash rates.
3. Three-Inch NPT Inlet & Outlet Connections.
4. Solid Brass Valve assures durability and long life.
5. Hydraulically-balanced Piston, Seal, and Spacers.
Lower service piston is available with or without hard
water by-pass. Non-sticking Teon-coated Piston al-
lows foreign particles to pass through without damaging
the unit.
6. Upper Piston pilots the regeneration steps of backwash,
brine and slow rinse, fast rinse, and brine tank rell.
7. Separate “Time-ll” Brining with accurate ow controls
allows automatic brine tank rell. Brine Tank Rell
Rates are easily adjustable on the cycle programmer. No need to worry about adjusting oat valves or
repositioning brine plugs for salt measurements.
8. Heavy-duty Drive Motor receives signal from timer
to efciently direct water ow during regeneration.
Piston shifts smoothly and quietly regardless of water
pressure.
9. Lower Heavy-duty Drive Motor receives signal from
upper drive motor to direct the service piston into position. Piston shifts smoothly and quietly regardless of
water pressure.
10. TNT Series Timer provides fully automatic, dependable timing for regeneration. The Cycle Programmer
regulates all regeneration cycles which are easily
adjustable. For manual regeneration start, simply turn
the service indicator clockwise.
