Engineered Plastic Cooling Towers

When you buy something, you want it to last, right? Well, that is the problem with your standard metal cooling towers.

This is due, at least in part, to the fact that metal-clad towers have casings with thin sheets of galvanized steel that have to be welded together. These welded seams will deteriorate, often within just a few years.

Once that happens, they’ll need to be re-welded or patched on a regular basis for the rest of their operational life.

While water alone is enough to eat through the galvanized metal, water treatment chemicals will also shorten their lifespan.

That’s really just the tip of the iceberg; environmental conditions such as sunlight, pollution, salt air, and harsh process chemicals also contribute to galvanized steel’s early demise.

Even low-grade stainless shell options, like series 300 stainless steel that’s designed to resist corrosion, wear out from water treatment chemicals and environmental factors.

Antimicrobial Cooling Towers

Antimicrobial Cooling Towers

Antimicrobial towers make more sense now than ever before.
There are a number of governments across North America that are discussing new legislation that will regulate cooling towers. The issue revolves around outbreaks of the potentially fatal Legionnaires’ Disease—of which cooling towers are often cited as the source.

The good news is, our antimicrobial cooling towers have already solved the problem. Manufactured with special antimicrobial resins, which are fully compounded into the cooling tower material, our towers operate on a cellular level to continuously disrupt and prevent uncontrolled growth of microorganisms and biofilm.

This has led a number of proactive school systems and hospitals throughout the country to spec the Delta Cooling antimicrobial design.

While cooling towers have been a mainstay in many heavy industrial cooling applications for decades, according to industry analytics, the adoption of the technology is significantly increasing for a number of reasons. Most notably longer average lifespan, lower maintenance, and significant energy savings over alternative cooling options.

Anti-Microbial Towers by Delta Cooling Towers installed at Lincoln Hospital in NY, was mentioned in an article posted on Healthcare Facilities Today about protecting cities from Legionnaires’ disease and other waterborne diseases.

“These towers, which are rounded, not only solved the circulation problem but also have anti-microbial chemicals embedded into the tower’s HDPE material, which helps to prevent the growth of dangerous bacteria such as Legionella,” he says.

The towers the hospital selected were made by Delta Cooling Towers, which introduced the HDPE (high-density polyethylene) cooling tower in the 1970s.

While some cooling tower manufacturers now market a tower with an anti-microbial fill (the medium over which the hot water is distributed as it is being cooled), a vastly better option is to have a cooling tower featuring the fill, structural casing, and sump all composed of anti-microbial material.

How to Save Money with Delta Cooling Towers

How to Save Money with Delta Cooling Towers

If you’re in charge of any aspect of your business, one of the main questions you focus on for each purchase you make is: is the value of the product worth the actual price you’re paying?

According to ACHR News, the value added to that specific product is just as important. Things like a trusted warranty, assistance with installation, engineering help, and excellent service can increase the overall worth of that product or piece of equipment.

Cooling water towers for businesses are extremely important and ones with added value include tremendous benefits. Quality cooling towers can improve water efficiency and trim the cost for any business and can be done relatively easily, depending on the product you’re using.

If your business is operating with a standard-efficiency motor on your cooling tower, you may be spending too much on energy prices. Replacing that motor with a high-efficiency motor can lower energy requirements by up to eight percent and improve water efficiency.

The buildup of foulants and corrosion on cooling towers can hinder the overall cooling efficiency. This accumulation can lower energy efficiency by more than 5% and could end up costing you much more. Just doing a 5% efficiency improvement on a 1,000-ton cooling system can save almost $10,000 a year.

The added value to look for when dealing with cooling towers is an unbreakable warranty. Delta Cooling, for instance, uses a 20-year warranty on every engineered plastic cooling tower shell and are not harmed by the most aggressive water chemical treatments. These cooling towers are manufactured to be durable and last many years. It’s nice to have that peace of mind.

Delta Cooling Towers – Modular Plastic Cooling Towers Facilitate  Increased Manufacturing Capacity

Delta Cooling Towers – Modular Plastic Cooling Towers Facilitate Increased Manufacturing Capacity

Replacing a failing galvanized cooling tower with a high-efficiency plastic system enables wire manufacturer to dramatically increase manufacturing capacity.

Cooling towers, used to reduce the heat of circulating water used to cool industrial processes and HVAC systems throughout the world, have undergone substantial design changes over the years. This is particularly noticeable with the introduction of HDPE (high-density polyethylene) cooling towers, which are recognized for providing longer service life with reduced maintenance requirements.

While these attributes are compelling, the idea of incorporating this technology to increase production capacity is, for many, an unexpected benefit of the HDPE cooling tower technology.

An example of this capacity benefit occurred when Tencarva Machinery was asked by Strand-Tech Martin, a leading manufacturer of prestressed concrete strand and high carbon wire, to evaluate a galvanized cooling tower that had required extensive service over its lifespan, and was beyond repair.

Tencarva Machinery is a distributor of liquid process equipment and custom engineered systems, most of which incorporate pumping packages and electrical controls. The company serves industrial and municipal markets in the Southeast.

“Our inspection made it clear that the existing cooling tower, a typical galvanized model, was beyond practical repair,” says Chad Plott, of Tencarva. Plott explains that the main problem was a destructive, corrosive effect on the metal-clad shell produced by salt air that permeates coastal areas such as Charleston SC, where Strand-Tech Martin’s manufacturing plant is located.

The process used by Strand-Tech to produce its PC strand wire and high-carbon wire products requires a cooling tower for the wire-drawing machines, which run at very high temperatures.

“They were barely getting enough cooling from the old tower, and really wanted a cooling tower that would allow them to expand the number of machines they run,” Plott adds.

The Strand-Tech application is an open cooling system, Plott explains. It includes pumps that feed water to the wire drawing machines from the cooling tower. The cooling water goes through some heat exchangers on the wire drawing machines, and provides some spray cooling on the machine, and also travels through coolant passages in the wire drawing dies. Eventually, the water gravity-feeds from that production equipment back to the cooling tower.

When Plott was asked to make a recommendation for a replacement cooling tower, he suggested an HDPE type of tower manufactured by Delta Cooling Towers ( HDPE engineered plastic cooling towers are designed to solve corrosion problems, which have plagued metal towers due to problems such as soft water, aggressive water treatment, and ambient factors such as salt air or caustic industrial gasses.

The design that Tencarva selected for the wire production facility was the TM Series, a modular cooling tower system that allows isolation of up to eight cooling cells for maximum operational flexibility. Plott recommended a four-cell configuration, which can produce up to 1,580 cooling tons.

Boosting capacity

Plott explains that one of the primary reasons for the customer’s inquiry into a new type of cooling tower was that because, in addition to structural damage, the old tower’s efficiency had fallen off. As a result, cooling capacity was only marginally sufficient for production, and the company was looking to increase production capacity significantly.

Plott says that since the new HDPE tower system was installed, in late 2014, it has provided an additional 30 percent cooling capacity, more than enough for the added production output his customer has required, and will likely meet additional production increases in the foreseeable future.

If yet more cooling capability had been needed, the modular design of the TM Series could easily have allowed doubling the capacity of the four-cell cooling tower that was recently commissioned via the installation of an eight-cell version.

Supplemental benefits

In addition to solving the corrosion and cooling capacity problems, Plott says the new cooling tower technology has provided other significant benefits to his customer.

Among those is the 20-year standard warranty on the double-walled HDPE shell, which is a standard warranty on all Delta products. Also, the tower fans now come with direct-drive motors which relieves the maintenance and downtime issues commonly associated with belt-driven or gear reducer systems.

“This is the high bar among industry products,” Plott says. “And I think it attests to the longer life expectancy of the HDPE type of tower design.

Another built-in advantage is the cooling tower’s higher efficiency, including the fan drive system. It is composed direct drive fans staged, with two fans per cell. “This staged design means it’s not always necessary to run all of the fans continuously,” Plott says. “The payoff is a substantial savings on electric power consumption.”

The ease of installation of the four-module cooling tower was also an unexpected benefit. Because Delta products are pre-assembled at the factory, installation normally goes quickly and easily.

“As far as installation was concerned, nothing unexpected occurred,” Plott says. “Tencarva supplied the pumps and cooling tower, and the customer provided a contractor who performed the installation. Even with the modular design, installation was fairly easy to complete. The installers were able to use the existing footprint as well as use the same water storage area underneath the cooling tower mounting pad.”

Maintenance is another positive. Not only will the corrosion problem of the salt air become obviated, but also the simplicity of the direct-drive fan system will require minimal service.

In the end, the new solution will provide the best of both worlds, added production capacity with no maintenance headaches or downtime surprises.
