Cooling Towers

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...

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...

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...

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...

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...
