Boiler & Cooling Tower Control Basics Series Installment 1

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, […]

Boiler & Cooling Tower Control Basics Series Installment 4

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. […]

What Is The Difference Between A Diaphragm Pump And A Peristaltic Pump?

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 […]
