COOLING TOWER & CHILLER FEATURES

The Impact of Water Utility Rates on Chiller Selection

By Judith M. Peters, Daikin Applied Americas

Do water-cooled chiller plants still deliver lower utility bills? Today, many chiller plant energy analyses carefully account for energy costs, and even energy escalation rates – a factor that projects how fuel costs will increase over time, while ignoring water and wastewater costs associated with cooling towers. While highly effective at transferring heat, cooling towers consume millions of gallons of water each year through the process of evaporation, drift, and blowdown. With the rising cost of water and wastewater, this omission can result in an incomplete picture for the building owner.

Central Chiller Plant Upgrade Helps Plastics Extruder Grow

By Mike Grennier, Chiller & Cooling Best Practices Magazine

At the company’s production plant employees manufacture a complete range of engineered, high-performance polymers. At the heart of the operation are numerous extrusion lines and related equipment that operate 24 hours a day, five days per week to produce and ship as much as five million pounds of high-performance polymer pellets each month. The process of producing pellets begins when the rotating screw on each extruder accepts a carefully calibrated mix of thermoplastic materials, as well as additives, from a hopper and pushes the mixture into the extruder’s barrel.

WATER TREATMENT & COOLING SYSTEM ASSESSMENT FEATURES

Plant-Based Water Treatment at USFCTG Improves Sustainability & Uptime

By Chris Kent, Contributing Editor

For U.S. Flue-Cured Tobacco Growers, Inc. (USFCTG) sustainability is a guiding practice for tobacco production from seed to delivery. So when traditional chemical water treatment had proven problematic in air washers at its plant in Timberlake, North Carolina, the company thought outside the box for solutions to address a variety of issues while also supporting its sustainability goals.

Water Screen Maintenance Improves Cooling Tower Efficiency

By Jon Southworth, Cambridge Water Screen Systems

Field-erected evaporative “wet” cooling towers, combined with heat exchangers, are an economical and efficient method to dissipate large heat loads at oil and gas refineries and chemical processing plants – as long as they’re free of harmful debris. Yet many cooling towers at these facilities are highly susceptible to poor performance and costly downtime due to problems associated with debris buildup and potential for debris to pass by traditional stationary water screens during the cleaning process, clogging heat exchangers.
