Four Reasons to Consider Plastic Cooling Towers

Today's "engineered plastic" cooling towers offer significant advantages over traditional galvanized steel models.  Plastic can reduce process interruptions while shaving construction, maintenance and replacement costs.

Here are four big reasons why you might want to consider an engineered plastic cooling tower to reduce costs and better meet your process requirements:

1. Life expectancy
Standard metal cooling towers have casings with thin sheets of galvanized steel. These sheets usually have welded seams that can deteriorate within a year and will require re-welding, patching or coating to prevent leakage.  Delta Cooling Towers engineers molded plastic cooling towers that are one-piece, so there are no problems with seams, welds, and patches that wear prematurely.  Competitive in price with standard metal towers, engineered plastic cooling towers are also rust and corrosion-proof.  The towers are rotary-cast with a single or double-wall UV-protective, with a polyethylene shell that is virtually impervious to weather conditions and harsh environmental elements. The warranty on engineered plastic cooling towers is indicative of their durability. The casings on the towers offered by Delta cooling are backed by a comprehensive 20-year warranty.  

2. Flexible modular design
In the past, plastic cooling towers were too small for many industrial processes. For that reason, galvanized metal cooling towers were traditionally a "given" for most applications above 250 tons. Processors requiring high-capacity cooling were forced to build custom-designed towers on site, often at a high cost in labor and materials. Today that situation has changed dramatically. Delta, for instance, has introduced its TM Series® of factory-assembled plastic towers that can be combined to provide up to 2,000 cooling tons in a single, modularized unit. 

3. Continuous, more economical operation
Engineered plastic can also reduce the expected and untoward consequences of operating a cooling tower, which include: electric power usage, water-treatment chemicals, labor and materials for maintenance, and unscheduled process downtime for cooling repairs. 

4. Easier installation
The inherent design advantages of the latest plastic cooling towers also include easier installation (especially on rooftops) because a lightweight plastic shell weighs as much as 40% less than a steel tower, while being 5-10 times thicker.  When modular cooling towers are combined in a cluster, installation is often faster and easier.  For applications that require mounting flexibility, Delta pioneered an induced-draft, counter-flow design that incorporates I-beam "pockets" in the tower basin for reinforcement, so that a plastic tower can be easily mounted on standard I-beams or imperfect concrete pads.
