High Efficiency Fill

Posted by: Jim Smith | General

This is a scenario we walk through on a regular basis with many of our customers. We also perform a lot of thermal runs using our STAR program to model towers and compare the benefits of using a cross-fluted fill or an offset-fluted fill. When we present a STAR analysis and customers see that a certain high-efficiency fill might be...


Alliance to Prevent Legionnaires’ Disease

Posted by: Jim Smith | General

An alliance to prevent Legionnaire's disease has recently launched PreventLegionnaires.org, a brand new website aimed at providing the public with information about Legionella bacteria, its source and how individuals become infected with Legionnaires' disease. The website launch coincides with the release of the CDC Vital Signs and Morbidity and Mortality Weekly Report (MMWR), confirming that "the most common source of building-associated Legionnaire's disease outbreaks...


Cooling Tower Water Management

Posted by: Jim Smith | General

Cooling towers dissipate heat from recirculating water used to cool chillers, air conditioners, or other process equipment to the ambient air. Heat is rejected to the environment from cooling towers through the process of evaporation. Therefore, by design, cooling towers use significant amounts of water. Overview The thermal efficiency and longevity of the cooling tower and equipment depend on the...


Drift Eliminator Best Practices

Posted by: Jim Smith | General

Drift removal is more than a function of simply putting a drift eliminator into a tower. Installation quality and workmanship are some of the largest factors that affect drift capture in a cooling tower. Even if you purchase and install the best eliminator that money can buy, if the air is able to bypass the eliminator, you will be allowing...


Getting Your Fill

Posted by: Star Cooling Towers | General

By Jim Wallis and Rich Aull, July 1, 2005 There are two broad categories of fills: splash and film. Splash fills typically are used where water quality is poor and where fill fouling can occur (table 1). Splash fills work by breaking up the hot circulating water into small droplets that create an increased surface area, which allows for both convective and evaporative...


Brentwood Repacking Crossflow Towers with XF75

Posted by: Jim Smith | General

Brentwood's AccuPac XF75, XF75IL, and XF75ID crossflow fills are suitable replacement fills for all manufacturers' crossflow cooling towers, including Marley, BAC, Evapco, and more. Specially designed for today's higher capacity cooling towers, where high water loading and air velocities are the norm, they replace the OEM hanging sheets with solid modules of rigid PVC film pack. Once installed, this system...


Enhanced Cooling Tower Maintenance Saves Water

Posted by: Star Cooling Towers | General

Source: www.mt-online.com Written by William F. Harfst, Harfst and Associates, Inc. Wednesday, October 1, 2008 Any amount of wasted water is too much. Perhaps it's time to compare your maintenance procedures to current best practices. Do they measure up? Water is an undervalued utility. Since many consumers essentially view it as a “free” resource, many plants make little effort to conserve water...


3 Reasons to Rebuild Your Tower

Posted by: Star Cooling Towers | General

Source: Process-Cooling.com Many managers do not consider or are not aware of the role of cooling towers and the application of cold water. A cooling tower is a high-energy utilization machine as well as a mass heat transfer device. Frequently, cooling capacity is the limiting factor in high unit production. After a cooling tower has been erected, proper operation and...


Cooling Tower Wood Maintenance

Posted by: Star Cooling Towers | General

In the past, redwood was selected for use in cooling towers because of its high strength-to-weight ratio, availability, ease of use, low cost, and natural resistance to decay. Pressure-treated Douglas fir and similar types of wood are replacing redwood due to cost and availability factors. Wood is composed of three main components: cellulose, lignin, and natural extractives. Long fibers of...


Care Is Needed For Cooling Tower Fans

Posted by: Star Cooling Towers | General

The main safety issue is with the fan blades themselves coming out of the fan: large projectiles can be sent many meters across the plant area. In one incident, a solid aluminum fan blade escaped from the plenum chamber and flew across a plant. The cause was down to the fan blades catching on the fan cowl and the fan...
