Cooling tower operators and maintenance engineers cite several common pain points associated with gearbox operation and service. Key features help minimize maintenance demands and extend operating life.
Industries that require process heat rejection often use field-erected cooling towers to keep pace with the heat load. Cooling towers have large fans and motors that can present worksite challenges, including excessive sound and vibration. Gearboxes are employed to address these challenges.
Thermal spray coating is an industrial coating process that consists of a heat source (flame or other) and a coating material (in powder or wire form). The coating is melted into tiny droplets and sprayed onto a surface at high velocity. Upon impact, a bond forms with the surface. Repeated passes build up the thermal spray coating and form a layered structure.
It is critical that process cooling systems relying on cooling towers have robust but cost-effective filtration equipment for water reuse. Cooling tower water frequently contains hazardous materials that should be managed to avoid reintroducing them into the process cooling equipment or system.
When compared to space cooling, process cooling — or the removal of heat from the fluid that serves water-cooled equipment used in a manufacturing process — is a bird of a different feather. Interesting though — and the source of some fascination among those in the cooling trade — is that much of the equipment, tools and techniques remain the same.
The mechanical rooms in large multi-building industrial facilities are the hub of process temperature and climate control. Areas such as central utility plants, boiler and chiller rooms, mechanical and electrical rooms, and fuel rooms house myriad process cooling and heating equipment as well as systems for comfort heating, ventilation and air conditioning equipment and systems.
Electrical equipment is almost always specified by manufacturers for operation within an optimal temperature range. That range is defined by the conditions that will ensure the equipment’s reliability, performance, efficiency and physical integrity are protected.
In countless process facilities, power plants and oil fields across the country, machinery is hard at work producing materials, electricity, oil, gas and other goods that keep the U.S. economy humming.
Shell-and-tube heat exchangers — first introduced in the 1900s — have long been used in all types of process applications because of their robust design. Shell-and-tube heat exchangers are able to withstand high pressures and temperatures, and these features are among the reasons for their wide use.
Manufacturing processes can produce adverse ambient conditions that can affect employees, production uptime and product quality. Using ancillary systems with production equipment can produce excess heat in the building, sometimes increasing the ambient temperature by 20°F (11°C) or more. These temperature fluctuations can create a difficult environment for employees as well as equipment.
Steam is essential in the production of many consumables, including dairy products, processed foods, beverages, chemicals and pharmaceuticals. Similar to compressed air, steam often is considered a utility or energy source — generated at a central location and then distributed to various points of use throughout the facility.
