Commercial
Top Mount Valve Water Softeners
Hurst Boiler HBM ST
Series water softeners are suitable for commercial application ranging
from 10,000 to 25K grains of hardness removal capacity at flow rates up
to 10 gpm.
Operation of The Softener
Hard water contains dissolved minerals in the form of Calcium (Ca), Magnesium (Mg),
and Iron (Fe). Removal of these minerals is accomplished by softening the water
through an ion exchange process. As water flows through the mineral tanks, the
dissolved minerals become attached to the resin. Over a period of time the resin
will become exhausted, and the softener will regenerate using a brine solution.
Softening Media
The exchange media is a high equality strong acid softener (Caution) resin in the sodium
form with a very high whole bead count, no color throw, physically hard, and is
chlorine resist. The media combines high operating capacity with excellent chemical
and physical stability for long dependable life. Request media specifications for
details.
Choice of Controllers
Regeneration cycle can be initiated by day time-clock, or optional meter. The unit
can either be single tank system or a duplex with a choice of meter systems.
Regeneration Controller
The HBM Series softener models are controlled by a reliable Fleck electro-mechanical
controller. The controller has either a 7-day or 12-day clock that initiates regeneration.
A fully adjustable 5-cycle timer delivers a controlled upflow backwash, downflow
brining and slow rinse, rapid rinse, brine refill, and downflow services.
Control Valve
The sequence control valve operates on commands from the valve controller. A hydraulically
balanced piston glides effortlessly along non-corrosive spacers and seals to a
precise position. This precision motor-driven valve performs in the toughest applications
and is made of high quality brass for a long and reliable life.
Resin Tanks
All HBM Series softener models feature a non-corrosive fiberglass tank, with a one-piece
thermoplastic inner liner. The tank has a maximum working pressure of 150 psi and
a working temperature up to 120 F. The tank is approved by NSF, UL, and meets WQA
Standards S-100, and FDA. All fiberglass tanks carry a 5- year warranty.
Brine Tank
The brine tank is a combination brine maker and salt storage vessel and is made of
though, high-density polyethylene. Brine tanks 24” diameter and smaller feature
a grid plate for maximum saturation of brine. Larger tanks are available for extra
salt storage capacity.
Brine System
Brine refill is automatically controlled, by the timer/controller, to provide the correct
amount of brine for each regeneration. (The Optional Brine System has a float and
safety valve shut-off, which minimizes the chance of overflowing the brine tank.)
Options:
1. Water Meter Regeneration
- Immediate/Delay - single
tank.
- Twin Interlock - Parallel
service twin tank system using 2 meters, both units on line, with lockout
to prevent simultaneous regeneration.
- Twin Alternating- Alternating
service using one meter. One unit is always on line, while the other is
regeneration or in standby.
2. No hard water bypass
is an option.
