COMMERCIAL APPLICATION PARAMETERS 1. HEAT EXCHANGERS, CHILLERS systems on hot and cold input feed lines both sides of the exchanger. 2. BOILERS, NON-DOMESTIC WATER HEATERS a) Hot Water Boilers (non steam): Treat both inbound & outbound recirculation loops. b) Steam Boilers: Treat both inbound recirculation loop and return condensate line. 3. COOLING TOWERS Units before all sprayers, and after the sump re-circulating pump. 4. RECIRCULATION PUMPS Since pump impellers break up a lot of the magnetic polarization always place unit after the pump to re-energize water if there is a long distance between process applications. 5. COMMERCIAL DISHWASHERS AND/OR ICE MACHINES on recirculation line past the pump. 5

7 COOLING TOWERS AND CHILLER APPLICATIONS Cooling towers do one job: cool the heated water that goes through the chiller to remove the heat from the refrigerant or other fluid that is used to cool the building or other applications. In water treatment the term cycle of concentration refers to the number of times the dissolved solids concentration in the circulating water has increased as a result of evaporation. For example, if the make-up water has 100 parts per million (ppm) of Total Dissolved Solids (TDS) and the chiller or cooling tower water contains 300 ppm that s 3 cycles of concentration. CYCLES OF CONCENTRATION AND MAKE-UP WATER The cooling tower cools the water by open air evaporation which loses a lot of water which is constantly refilled with make-up water. To reduce the tower and the tube bundle of the chiller from scaling, as the cycles of concentration increase, the TDS/Conductivity sensor reads the high concentration and bleeds off (purges) the concentrated water and refills the system with fresh water to reduce the high concentration. SAVINGS ENVIROMAGNETICS Water Softeners completely de-scale chillers and cooling towers. Once installed, all de-scaling chemicals can be turned off representing a large, continuous, yearly saving, and in addition the water softening system will reduce and eliminate the huge maintenance costs of down-time, drilling the tube bundles and acid treating the tower, chiller, piping, etc. ADJUSTMENT OF AUTOMATIC SENSORS Some TDS sensors work by sensing the hard water scaling on their probe. However, the ENVIROMAGNETICS water softening system normally stops any plating/scaling and nullifies that type of sensor from working. Adjustment must be made to make sure make-up water is being provided to run the equipment and reduce the concentration. MANUAL PURGING & MAKE-UP WATER The ENVIROMAGNETICS operates very well on increased cycles of concentration. This reduces the amount of purging and saves make-up water. But it is necessary to advise the maintenance engineer that the automatic cycle timer must be adjusted or the manual bleed-off must be used so there is no chance of the concentration getting too thick which will reduce productivity. With the huge savings ENVIROMAGNETICS eliminates on chemicals and maintenance costs; this is a simple, inexpensive procedure. INITIAL STABILIZATION PERIOD Please note: during the initial stabilization period, the concentration will build up faster as the scale is being dissolved throughout the entire system. This will require more purging during the de-scaling period. 7

8 BOILER & COOLING TOWER DE-SCALING BLOW-DOWN PROCEDURES FOR GOOD RESULTS: THE FOLLOWING CONDUCTIVITY/TDS LEVELS CAN BE MAINTAINED TO PRODUCE A SCALE FREE SYSTEM. BLOW DOWN FOR BOILERS: BLOW DOWN FOR COOLING TOWERS: To 800 TDS To 1400 ppm TDS To 1200 uhmo Conductivity To 2000 uhmo Conductivity ph to be maintained between 8.5 to 10.5 ph to be maintained between 8.5 to 10.5 ENVIROMAGNETICS Water Softener System performs well in a high TDS or Conductivity water chemistry because the increased TDS carries a higher mv (mill voltage) which is the mechanism that performs the de-scaling. Maintaining a reasonably high TDS or Conductivity level helps maintain the softening charge into the water. This is advantageous when descaling a boiler or cooling tower as purging the water can be reduced; it is important to note that during the original de-scaling period, the equipment must be blown-down more often so the TDS does not turn into a think soup. SPECIAL NOTES TO MAINTAIN TDS OR CONDUCTIVITY: o For Cooling Towers, utilize more clean-downs as opposed to blow-downs to keep TDS at desirable levels. This may be necessary as a lot of sediment may build-up in the receiving pan and must be removed. o In soft or mildly hard water areas, we recommend: Do not use a constant bleed, as this tends to keep the Conductivity/TDS very low. 8
