COLUMNS0 8 / 2 0FROM THE EDITORA Midwest-based plastic extruder is growing, thanks to their high-performance polymers. Theirageing 250 ton air-cooled central chiller plant, critical to the quality and reliability of the extrusionlines, struggled to keep up with demand and became maintenance intensive. A new 345 ton aircooled central chiller plant was installed, after an extensive analysis. Our own Mike Grennier hadthe opportunity to interview the team at CASCO USA, who did the system assessment and installation.The extrusion lines are now well-equipped to support more growth!Water Treatment & Cooling System Assessment FeaturesU.S. Flue-Cured Tobacco Growers (USFCTG) operate out of Timberlake, North Carolina wherethey produce as many as eight billion cigarettes per year. Their air washer systems are criticalto tobacco processing and are a significant user of cooling water. The cooling system consists ofthree chillers: a 1,250-ton Trane , a 370-ton McQuay and a 275-ton York chiller and three SPXCooling Technology Marley evaporative cooling towers. Our story is about how USFCTG’s focuson sustainability led them to replace their chemical water treatment program with an innovativeall-natural solution using moss.The proper maintenance of cooling towers is a huge factor for maintaining plant uptime and processquality. Jon Southworth, from Cambridge Water Screen Systems, has sent us an interesting articleabout the benefits, to reliability and uptime, of using traveling (vs. stationary) water screen systems.Best Practices EXPO & Conference AnnouncementsPlease consider reserving portions of September 23-24, 2020 for the Best Practices 2020 ONLINEEVENT!

In her article, “The Impactof Water Utility Rates on Chiller Selection,” Judith Peters from Daikin Applied Americas, examinestraditional metrics like kW/ton and discusses other metrics used less often – like water treatmentand wastewater costs associated with cooling towers.Cooling System AssessmentsSummer is in full swing and we hope you are finding time to get outdoors. Ourteam here wishes all of our readers safety and sanity during this unique periodin our lives. We are all working from home very productively and hope to lookback upon this as a time when we actually improved some processes.CHILLER & COOLING BEST PRACTICESEDITORIAL ADVISORY BOARDDoug BarndtManager, Demand Side BallEnergy-SustainabilityCorporationBhaskar DusiCorporate EnergyManagerCEMEX USARichard FeustelSenior Energy AdvisorLeidosWilliam JeraldEnergy ManagerCalPortlandKurt e MarshallCorporate EnergyEngineerGeneral MillsBrett Rasmussen Senior Utilities EngineerNissan NorthAmericaBrandon AitkenEngineering ManagerBlackhawkEquipmentHoward KielarManaging DirectorMTA USAE.
