How to Choose cooling tower fill?

Before you choose the cooling tower fills, you should know more your cooling tower condition and decide which types of cooling tower fills are best for you from the following aspects.

You will get efficient and thoughtful service from Longzhuo.

Crossflow cooling tower or counterflow cooling tower

There is different air flow in the crossflow and counterflow towers, so the cooling tower fills are also different for the maximum efficiency.

Film fill and splash film

There are two main types of cooling tower fills, you should decide which one is best for you.

• When the water is relatively clean and has good circulation. Either the film-fill and splash fill are available. This will be the expected condition in the majority of normal applications
• If the circulating water is anticipated, splash film will be the only choice. Typical industry includes food processing, paper processing and the processing of soaps and cosmetics.
• If the cooling tower fills will work in a dusty or wooden environment, or whose make-up supply will come from unclarified water, splash fill should be selected.

Material choice

You should choose the right cooling tower fills according to the working temperature and conditions.

We all know that "fill" is the heart of every cooling tower. We also know every cooling tower operates with differing environmental constraints, water quality and thermal performance needs so there is no "one size fits all" when it comes to choosing fill for your project. Whatever your needs, we have them covered from splash filled crossflow components to high efficiency film fill and everything in between. 

Counterflow fills

When selecting a counterflow fill many factors must be considered. Your customers are looking for reliable thermal performance as well as durability in the product; you can deliver both with CE Shepherd fills.

We have fills available in various sheet thicknesses and profiles for virtually any application. If you need help selecting one, just give us a call or refer to the "Technical Resources" section of this website for guidelines based on water quality. For thermal performance assessments, give us a call and we will help you choose the most cost effective fill for your specific application.

Crossflow Fills

"Gull Wing" fill, available in 4-inch or 6-inch widths, is our latest and most efficient fill slat offering. The unique design of the Gull Wing Fill effectively addresses two key concepts clearly lacking in the majority of competitive fill slats: span and water bypass. Span is assured with full bearing surface contact between the slat and hanger and a center rib stiffener for increased strength. A unique retainer notch placed at regular intervals creates a space for the hanger grid while providing a full eighth-inch overhang per side to virtually eliminate water bypass. Gull Wing fill bars are manufactured of extruded PVC with either carbon black or titanium dioxide as a UV inhibitor. The fill bars are 50 mil (+/- 0.005") thickness with a uniform hole punch pattern surface to aid in water break-up.

"V-Bar" splash bars are also available and, like "Gull Wing", are manufactured of extruded PVC with either carbon black or titanium dioxide as a UV inhibitor. The fill bars are 50 mil (+/- 0.005") thickness with a uniform hole punch pattern surface to aid in water break-up.

And of course crossflow fills need quality wire hangers and accessories to insure reliable installations.  For many years CE Shepherd has been the leading crossflow fill hanger wire manufacturer offering both fusion bonded pvc coated galvanized steel wire as well as stainless steel hangers.  Our crossflow systems also include hanger brackets for attaching the wire hangers to the cooling tower structure as well as retainer clips for securing the fill bars to the hanger wire.  We are truly a "One Stop Shop" for crossflow fill systems.
