For those of us who have been around boilers and cooling towers for years now, it can be easy to forget how we may have struggled when we first learned about controlling the chemistry of boilers and cooling towers. After running all the chemical tests, where do you start when the phosphate is too high, […]
BEYOND CYCLES Whether we’re talking about boilers or cooling towers, we know if we reduce blowdown, cycles will increase, and if we increase blowdown, cycles will decrease, We also know the other constituents in the water (phosphate, sulfite, molybdate, etc.) will change in the same direction as the cycles change. The only time this rule […]
BEYOND OVERFEED / UNDERFEED There are other factors that can lead to constituent being out of range besides a chemical overfeed or underfeed, and these must be considered before a change to the feed rate is made. Perhaps a piece of equipment isn’t operation properly or process contamination is occurring. By knowing the system, equipment, […]
Keeping a cooling tower or a boiler within parameters. CHELANT TOO LOW The purpose of the chelant (typically EDTA) in a system is to combine with metal ions to keep them soluble so they won’t from scale in a boiler. Any metal ions that are in a boiler such as calcium, magnesium, iron etc. make […]
Keeping a cooling tower or a boiler within parameters. CONSTITUENT LEVELS TOO HIGH For the same but opposite reasons in the other examples published earlier, constituent levels may be too high. Perhaps a heat exchanger has been fixed and hardness is no longer contaminating the condensate. Then chelant or phosphate levels may suddenly be higher. […]
The Stenner Pump Company has just developed the new quick pro pump head. We are really excited about this head because you can now replace the tube without running the pump or having to use a screw driver. Plus the Stenner tube assemblies were redesigned as well. The tube fittings are now molded directly onto […]
A diaphragm pump such as the Pulsafeeder Pulsatron C series LC54SA-VHC1-XXX uses a positive displacement diaphragm powered by an electronic solenoid. There is no motor needing a fan for cooling so the pump is completely enclosed and rated for outdoor use. There is a stroke length knob to adjust flow down to as low as […]
Pulsafeeder has developed a new stand alone flow meter. This meter (without the controller) can be used as a standalone Hall effect meter for use with XPV Series and Micro Vision series products as well as any product that has a Hall effect input. The meter is available with a controller that has a 4-20mA […]
Chlorine is an element used in industry and found in some household products. Chlorine is sometimes in the form of a poisonous gas. Chlorine gas can be pressurized and cooled to change it into a liquid so that it can be shipped and stored. When liquid chlorine is released, it quickly turns into a gas […]
It is with great excitement that Pulsafeeder brings to us the information on the New High Speed Pulsatron A Plus Series product. The new version of these (3) new pumps sizes (S2, S3 and S4) are NOW AVAILABLE FOR SHIPMENT!! This new offering has gone through extensive testing to deliver outstanding performance in the most […]
