Cooling Towers

Common problems associated with untreated cooling tower/evaporative heat exchange water are scale formation, biological fouling and corrosion.  Scale deposits in cooling towers will minimize the effectiveness of heat transfer and the flow rate of the water distribution system.  Cooling towers are incubators for microbiological growth.  The interior of a cooling tower is a warm, humid and radiant environment in which a variety of microbiological types thrive.  Untreated corrosion will lead to two problems: deterioration of equipment with replacement cost and the system downtime and decreased system efficiency due to loss of heat transfer (metal oxides are not effective heat conductors). Effective water treatment will reduce energy cost, equipment deterioration and downtime.
Our water treatment programs and quality products are tailored to your application and specific needs. P/PM Services utilizes blended products to inhibit scale and corrosion. This means fewer chemical containers onsite. We also have a menu of biocide products to control micro-organisms and unsightly algal growth.

We have our own laboratory located in South Houston, where all the samples are tested thoroughly and reports generated. Reports can either be mailed, emailed or uploaded to your WaterAccess account.

○Cleaning Services for Towers and Chillers

All closed loops should be treated and monitored for fouling and corrosion. Rusty water? Reduced flow? Insufficient heat transfer? Our products can effectively treat these issues.

○Incoming Process Water

Cooling towers not only transfer heat, but collect all the dirt and debris from the surrounding air. Most cooling tower manufacturers suggest cleaning every 6 months. Dirty towers can lead to fouling and increased biological growth (from microbes to trees!). We can keep your machine clean either as a scheduled service or on an as needed basis.

If needed, we can also clean the scale and fouling out of chiller and boiler tubes. Clean tubes are essential for heat transfer and lower energy bills.

The presence of scale or corrosion in a boiler can dramatically reduce efficiency and eventually lead to the deterioration of boiler tubes and/or catastrophic failure. Without water treatment, minerals dissolved in the water supply such as limestone (CaCO3), silica (SiO2), and gypsum (MgSO3) will accumulate on boiler tubes and function as an insulator. As heat transfer diminishes, fuel usage rises. Overheating and higher maintenance expenses may result. Corrosion in a boiler will cause structural fatigue and equipment failure. Steam condensate is also naturally acidic, which is another, potentially costly, corrosion issue. It is essential that boiler water is properly treated to avoid fouling, corrosion and increased operating costs. In conjunction with a comprehensive treatment program, our products are designed with the longevity of your equipment and condensate piping in mind.

○Heat Transfer Loops

Garbage in, garbage out: effective water treatment starts with the incoming water. P/PM Services can supply the flocculants, softeners, salt and chlorination needed to do the job.
