Marley NC cooling towers, for example, are composed of about 70 percent recycled material when the structure is manufactured out of stainless steel or 29 percent when manufactured out of galvanized steel.
Our cooling towers frequently use gearboxes containing oil for lubrication and cooling. The Marley System 5 Geareducer has been designed to operate five years between oil changes which greatly reduces the amount of oil that needs to be recycled.
It is important to note that LEED, the US national standard for green buildings, does not include large mechanical equipment such as elevators and air-conditioning equipment, which includes cooling towers, as a part of the recycled or regional sourced materials calculations.
UK-based magazine ACR News published our Q&A article, surveying engineers and design experts, that explains how cooling towers can contribute to successful LEED projects and other sustainability initiatives.
