A unit’s motor full load amps (or FLA) can be found in the technical data sheet for each specific cooling tower. It is also located in EVAPCO’s custom selection software, Spectrum, in the returned results table. To determine the FLA for other electrical accessories, please contact... READ MORE How do I clean my air inlet louvers? What are the benefits of a belt drive system when compared to a gear box drive system? What is the minimum recommended fan speed for an open cooling tower? Why would I use equalizer connections instead of a flume box? FLUID COOLERS What is a dry bulb switchover temperature? A dry bulb switchover temperature refers to the temperature at which a closed circuit cooler can run fully dry (with just the fans running, without the spray pumps on) and reject 100% of the design heat load. This is an important term in the engineering community as a higher dry... READ MORE Can I operate my closed circuit cooler recirculating pump on a VFD? When should I use glycol in my closed loop system instead of water? Where can I find the coil volume of my closed circuit cooler? Why do I need to maintain a minimum flow in my closed circuit cooler? What is the minimum flow I must maintain? WATER SYSTEMS Why is water treatment important in an evaporative cooling system? Effective water treatment works to control scale, corrosion, and microbiological growth within an evaporative cooling system. It also helps to ensure heat transfer efficiency and extend the service life of the equipment. When an evaporative cooling system rejects heat to the atmosphere, only pure water is evaporated. As this occurs... READ MORE What advantages does solid chemistry have over a traditional liquid chemistry program? How does the makeup water quality affect a cooling tower’s material of construction? How much water will I save using EVAPCO’s Water Saver™? Will Pulse~Pure® work for me? PARTS & MAINTENANCE Can EVAPCO provide replacement parts for another manufacturer's cooling tower? Yes. EVAPCO can provide replacement parts for any piece of cooling equipment you have onsite. For specific parts and pricing (or custom requests), please contact your local sales representative. EVAPCO has been offering parts for non-EVAPCO cooling equipment for many years. We have a dedicated Custom Design Team, as part... READ MORE How long (in general) does cooling tower fill last? I need to improve the maintenance access to my cooling tower, condenser, or fluid cooler. Can EVAPCO custom fabricate ladders and service platforms to fit my installation requirements? My cooling tower is not functioning as well as it did when it was new. Is this normal? How do I get it running back to normal? TROUBLESHOOTING My cooling tower is overflowing because the mechanical float valve is stuck open. What should I do? The mechanical float valve that EVAPCO uses operates with a makeup water pressure between 20 and 50 psi. When the makeup water pressure exceeds the 50-psi limit, the makeup valve will not close. The reason for this is that the buoyant force of... READ MORE My tower was just installed and there is rust around the basin. What can I do? VIEW ALL FAQS Copyright © 2021 EVAPCO, Inc.
