Cooling Tower Maintenance: Prepare Now for the Next Summer Heat Wave

Heatwaves in California have become a national concern. The Association of Pacific Coast Geographers says that heatwaves have more than tripled over the past 100 years as a result of the steady warming of Los Angeles. Even more concerning is that global climate models have predicted more intense, more frequent, and longer-lasting heat waves in North America in the future. And the problem is not restricted to summer. Last month, the Los Angeles Times published an article with the headline “Fall heatwave turns ‘happiest place on Earth’ into hottest place in America” saying that the temperature

A Project in Line with Sustainable Development by EVAPCO

As part of a sustainable development policy, the City of Toulouse and the SEM for the development of Greater Toulouse Oppidea wanted to connect the ZAC Cartoucherie to the city's heating network for its heat needs. In the summer of 2022, two closed-type Evapco ESWA 142-34I air-cooling towers of 1250kW were installed in the P3 car park substation on the Zac de la cartoucherie tranche 2 in Toulouse (31) for the contracting authority Eneriance and its AMO Coriance. EVAPCO, Inc. was selected because the Super Low Sound Fan (SLSF) met sound requirements. Also, thermal performance is guaranteed with

Frequently Asked Questions - Fluid Coolers

A. What is a dry bulb switchover temperature? B. Can I operate my closed circuit cooler recirculating pump on a VFD? C. When should I use glycol in my closed loop system instead of water? D. Where can I find the coil volume of my closed circuit cooler? E. Why do I need to maintain a minimum flow in my closed circuit cooler? What is the minimum flow I must maintain?

Why would I use equalizer connections instead of a flume box?

Water equalization is required anytime there are two or more separate basins that are combined on the same condenser water loop. There are two main types of equalization: flume box or external equalizer pipe. Only one of these options is required. The default equalization method for multi-cell units is a flume box. The decision on whether to use a flume box or equalizer is typically determined by the person designing the system. External equalization requires pipework to be run (by others) between equalizer connections and is typically installed with a valve in the piping to facilitate

What is the minimum recommended fan speed for an open cooling tower?

EVAPCO recommends a minimum fan speed of 25% for each available open cooling tower. Operating below 25% of motor speed achieves very little return in fan energy savings and capacity control. This recommend also applies to closed circuit coolers and evaporative condensers. If you have additional questions about the operation of your cooling tower, please contact your local EVAPCO sales representative.

What are the benefits of a belt drive system when compared to a gear box drive system?

A belt drive system brings many advantages including lower upfront costs, simplified maintenance, lower replacement costs, and shorter lead time. Regarding maintenance, belt drive systems are much easier to service than gear box drive systems as they require no special tools, equipment, or skills. EVAPCO cooling towers feature extended lube lines—as standard—making it a simple process to grease the bearings. Gear drive maintenance comes with a higher replacement component cost, longer lead time, and advanced equipment requirements (since this process typically involves a crane). Belt Drive

How do I clean my air inlet louvers?

Cooling towers can often experience mineral/scale buildup on the exterior surfaces of their air inlet louvers. Improper water treatment, insufficient bleed rates, and/or excessive cycling of the fan motors are the most typical causes. Since the louver material is constructed of lightweight PVC, it cannot withstand the rigors of heavy mechanical cleaning. Therefore, DO NOT USE A WIRE BRUSH OR PRESSURE WASHER TO REMOVE THE MINERALS/SCALE FROM THE AIR INLET LOUVERS. This method of cleaning will damage and/or destroy the louvers.

Where can I find the Full Load Amps (FLA) of a cooling tower’s electrical components?

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 the HVAC marketing team. If multiple components are utilizing different voltages, the FLA will need to be broken out for each voltage.
