White rust, which is a combination of zinc carbonate and zinc hydroxide, shows up as white spots and bumps on a galvanized surface. It is porous and generally does not protect a steel structure. Left unchecked, leaks can form in a cooling tower basin in as little as two months in severe cases.
Whether it is a food manufacturer following a plant ammonia leak, a food supplier relocating its freezer to a larger site, or an asphalt plant facing a potential temperature crisis, and emergency — or even a planned, temporary disruption — can disrupt business as usual. Companies in the process industries should consider their cooling and cold storage needs before demand strikes to keep their businesses thriving and minimize losses.
One of my favorite things in my early days of publishing was getting a new at-a-glance planner each December. Part calendar, address book and part personal guidebook, each new calendar offered smooth, unmarked pages full of potential.
Industrial process cooling equipment such as cooling towers or chillers can corrode before they are installed or while they are temporarily laid up for the season. This is especially so if equipment is exposed to harsh outdoor conditions during shipping or storage.
The Wilson E. Bradley Research Center in Taneytown, Md., contains eight environmental chambers for testing equipment for industrial process cooling, high pressure refrigeration and low pressure refrigeration and components. Evapco Inc. says its 60,000 ft2 facility is among the largest of its type in the refrigeration industries.
A steel plant had no choice but to use river water for its cooling towers. Adding electrodeionization water treatment equipment made it possible.

Water is an expensive resource for industrial companies, and it can be especially so for those that rely on cooling towers as a part of the manufacturing process. Cooling towers use a large amount of water on a consistent basis and are subject to scaling and corrosion issues. When the equipment is not maintained properly, an even greater amount of water can be used — and sometimes wasted.
Forging — a manufacturing process of shaping metal by applying a variety of powerful compressive forces to it — is known for producing parts that have excellent fracture toughness and ductility while also offering impact resistance and fatigue strength.
