A large containerboard mill located in southern Mississippi needed to replace the cooling tower used for its electrical rooms, along with an additional tower that supplied comfort air to the building’s offices. Both were the classic metal-clad design framed with wood and were beginning to disintegrate.
A test code for air-cooled fluid coolers — more commonly referred to as dry coolers — has been published by Houston-based Cooling Technology Institute. Its application is limited to the sensible cooling of water, aqueous glycol solutions and other homogeneous, single-phase process fluids. ATC-105DS applies to testing in both field and laboratory settings.
A technique that substituted a reusable liquid refrigerant in place of evaporative-water cooling towers when outside temperatures are low enough to make that feasible earned Sandia National Laboratories engineers and others a Department of Energy environmental award.
During process cooling, the cooling water absorbs large volumes of airborne particulate while the cooling tower acts as an air scrubber, filtering the surrounding air. With time, these fine particles can build up and settle within the system, adversely affecting cooling performance while lowering the life of wetted subcomponents.
When you make an equipment purchase, what — besides price, of course — influences what you buy and from whom? We’d all like to think that our buying choices, large and small, are based on good research and a judicious weighing of the costs and benefits of each option.
In applications ranging from industrial process facilities to data centers, many buildings require cooling — even in cold weather. Careful oversight is needed when operating cooling towers in subfreezing temperatures to avoid complications.
The XF75 cooling tower fill line includes a crossflow herringbone film fill pack, a crossflow herringbone film fill pack with a drift eliminator in the design, and a crossflow herringbone film fill with an inlet louver in the design. Suited for crossflow cooling tower systems, the cooling tower fill has a herringbone design to distribute water evenly over the entire fill area for maximum thermal performance.
BioSpray Tower will disinfect hard, nonporous surfaces, says the manufacturer. The EPA-registered disinfectant kills 99.9 percent of Legionella pneumophila when correctly applied to hard, nonporous surfaces like cooling towers.
A traveling, working closed-circuit cooler allows mechanical contractors and prospective users to look at the operation and efficiency of the units firsthand. Evapco’s eco-Air trailer recently began a West Coast tour in Los Angeles.
