The Sensory Twin series Residential and light commercial Water Softeners are suitable for Patriot Analyst Twin - incorporating the Pentair 9100TSi Control Centersoftening applications up to 100 grains per gallon of hardness removal capacity at peak flow rates of up to 22 gpm.

Operation of The Softener: Hard water contains dissolved minerals in the form of Calcium (Ca), Magnesium (Mg), Iron (Fe), Copper (Cu) & Zinc (Zn). Removal of these contaminants is accomplished by softening the water through an ion exchange process. As water flows through the mineral tank, the dissolved minerals become attached onto and inside the resin. Over a period of time the resin will become saturated with contaminants, and the softener will require regeneration using a sodium or potassium brine solution.

Softening Media – Hydrolyte 525-2 Hybrid: The exchange media is a high quality, FDA certified, commercial grade strong acid hybrid (Cation) structured matrix resin with a very high whole bead count, no color throw, physically hard, and is moderately chlorine resistant. Hybrid media is engineered to encompass all the attributes of 525-1 softening media and leverage select functions of 525-2 Conditioning media when working together with Pur-Gard or Pur-Gard Plus.  The media combines high operating capacity with excellent chemical and physical stability for a long dependable lifespan.

Controller/Meter: Regeneration of the system is initiated by a simplified electronic control timer, which electronically meters softened water flow to the home and makes decisions to regenerate based on water consumption and program settings as well as through input derived from the resin bed sensors.

Sensors: Two gold-plated sensors are included in each mineral tank to monitor the exhaustion-state of the ion exchange media. Sensors are connected to the main control computer through a simple bus, ensuring the system is constantly aware of sensor status. Sensors are periodically cleaned during service and have a long service life. The main control computer will adjust service runtimes according to sensor data and flow meter input, thereby ensuring maximum performance and salt-efficiency.

Regeneration: These softener models are controlled electronically. A fully programmable microprocessor controls tank switching, upflow brine/rinse, backwash, rapid rinse, tank fill, and return to service cycles.

Control Valve: Two hydraulically balanced, pistons slide effortlessly through seals & spacers.   All parts in the waterway are either Teflon coated brass or composite Noryl® materials for a long and reliable service life.

Resin Tanks: This softener model features two non-corrosive fiberglass tanks, with one piece thermoplastic inner liners. The tanks have a maximum working pressure of 90 psi and a working temperature up to 120°F. The tanks are approved by NSF, UL, FDA, and meet WQA Standard S-100. All fiberglass tanks carry a limited lifetime warranty.

Brine Tank: A 200lb capacity brine tank is included as part of the system.   The brine tank is a combination brine maker and salt storage vessel and is made of tough, high-density polyethylene.  Larger tanks are available for extra salt storage capacity, if required.

Brine System: Brine refill is automatically controlled by the computer to provide the exact amount of brine for each regeneration cycle. The Brine System has a float and safety valve shut-off, which minimizes the chance of overflowing the brine tank. All units are equipped with an air check.

Pur-Gard & Pur-Gard Plus: A high-efficiency capillary Pur-Gard dispenser & reservoir is included with this system to ensure peak performance and maximum protection from inorganic metals and minerals while maximizing system efficiency and maintaining bacteriostatic protection.
