American Services commercial heating and cooling installation in St. Louis, knows that there are advantages to the use of high density polyethylene based plastic cooling towers for commercial cooling.
Not only are polyethylene based plastic cooling towers becoming more popular in the U.S., but are growing in popularity in the Middle East as well. Cooling towers manufactured in the U.S. have been integrated into an advanced, solar-powered cooling project taking place in Abu Dhabi.
The Abu Dhabi project is a pilot program which was implemented in order to offer rooftop air conditioning to some of the city’s commercial buildings via concentrated solar panels that will provide clean renewable solar energy to the building during peak demand hours.
“Essentially, the project is using solar power to produce cold water that is used to provide air conditioning,” explained Mohammad Alkarmi, CEO of Limitless International Corp., Raleigh, N.C., the exporting organization that sold the plastic cooling towers to the project’s management.

The benefits of the system include significant energy cost savings, but also peak shaving from the rooftop solar cooling technology, which will result in better grid efficiency and reduced emissions.
“We believe that this unique cooling tower technology is the ideal solution for cooling applications in the Middle Eastern countries, where very high temperatures accompanied by high humidity — especially in the gulf region — would prevent most metal cooling towers from lasting very long because they would rust and corrode easily,” Alkarmi said.
The solar powered air conditioning project was a demonstration of the option to use the sun’s energy to provide cooling even in the heat of the desert. “Essentially, they are simply using the hot water that is coming from the solar panels to get cold water from the chiller,” Alkarmi stated.
The cooling towers play a vital role in the overall cooling system performance, and the reliability of the tower reliability was an important consideration when selecting the design.
“The HDPE plastic cooling tower will never rust or corrode, as opposed to either stainless steel or galvanized metal clad models, which will eventually rust and corrode,” Alkarmi said. “The Delta HDPE design does not require any coating or galvanizing or other exterior protection. It simply will never rust or corrode, and will last well over 20 years.”
The warranty coverage period was increased from 15 to 20 years because of the products history of long term performance.
