Light Commercial Twin Alternating Series Water Softener
Aqua Mech. LLC. LCTA 075100 Series water softeners (8 models) are suitable for light commercial applications ranging ROM 10,000 to 120,000 grains of hardness removal capacity at flow rates up to 24 gpm. Installations might include restaurants, car washes, laundromats, small boilers, and other light commercial applications. The LCTA is a twin unit alternating system where one unit is in service and the other unit is in standby.
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 tank, 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.
The exchange media is a high quality Mack strong acid softener (Cation) resin in the sodium form with a very high whole bead count, no color throw, physically hard, and is chlorine resistant. The media combines high operating capacity with excellent chemical and physical stability for long dependable life. Request media specifications for details.
Regeneration cycle can be initiated by day time clock or optional meter initiated regeneration cycle after a preset volume of water has been softened.
The LCTA 075100 Series softeners are controlled by a reliable Fleck electromechanical controller. The fully adjustable 5 cycle, single controller operates all steps and regeneration cycles for both vessels, including upflow backwash, downflow brining and slow rinse, rapid rinse, brine refill and downflow service. 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. A single valve regenerates and controls flow through both resin tanks.
All LCTA 075100 Series models feature non-corrosive fiberglass tanks, with a one piece thermoplastic inner liner. The tanks have a maximum working pressure of 150 psi and a working temperature up to 120’F. The tanks are approved by NSF, UL. and meets WQA Standard S100, and FDA. All fiberglass tanks carry a 5 year warranty.
The brine tank is a combination brine maker and salt storage vessel, and is made of tough, high density polyethylene and features a grid plate for maximum saturation of brine. Larger tanks are available for extra salt storage capacity.
Brine refill is automatically controlled by the timer/controller to provide the correct amount of brine for each regeneration. The refill system is backed up by a float and safety valve shutoff, which minimizes the chance of overflowing the brine tank.
The water meter is standard on all models. Regeneration is initiated when a preset volume of water is used. Once the meter gallon setting zeros out, the system automatically switches tanks and the exhausted tank goes immediately into regeneration. Once regeneration is completed the tank goes into the standby mode.
