![]() Although electrical control panels may appear straightforward in concept, many people, even those in industry, are not aware of exactly how panels are made. Modern industrial control panels consist of power circuits or control circuits (or both) which provide signals that direct the performance of machinery or equipment. ![]() As the predecessors of programmable logic controllers (PLC), they gradually replaced electro-mechanical control mechanisms and led to the development of the modern electrical control panel. ![]() Electromechanical pneumatic and hydraulic control devices fit the bill.īy the 1950s, solid-state digital logic modules were being used in industrial control systems. In the early 20 th century, factories began to transition to electric power and new types of mechanisms were developed to control equipment and production lines. Over the years, as factories grew and evolved, there was a need for more sophisticated control mechanisms. Steam powered factories ran continuously and had rudimentary control mechanisms. The belts could also be directed vertically through a hole in the ceiling to power machines on a second or third floor. Other shafts, connected via belts and gears, drove hammers, punches, presses, looms, and other machines. No matter what type of pump station you require, shade structures are beneficial for all types of electrical equipment.In the factories of the Industrial Revolution, steam engines powered a central steel drive shaft that ran along the length of the factory and sometimes continued outside into a second building. Romtec Utilities offers shade structures in 2-post, 4-post, and 6-post configurations and can include any mounting hardware necessary for your pump station application. Even seemingly harmless weather conditions can be enough to damage control panels. Providing weather protection to control panels and other sensitive electrical controls is an important design consideration for pump stations. Romtec Utilities designs, engineers, and fabricates these shelters in-house, we can meet whatever requirements necessary for your project and equip your shelter to mount any equipment needed. Lighting packages can be installed to provide 24 hour visibility for the pump station for surveillance and after-hours maintenance. When maintenance is required during a storm or heavy rain, personnel can troubleshoot issues from beneath the comfort of the shelter. Whenever Romtec Utilities provides a utility shelter with any of our pump stations, we prepare the structure prior to delivering it so that controls panels and other system controls can be easily mounted and installed directly on the structure. Mounting electrical controls and other equipment offers multiple benefits. Another advantage of these control shelters are the capabilities for mounting hardware directly to the structure. This allowed the electrical controls and other components to be installed directly outside the wet well with adequate weather protection. One project in Southern California required the installation of a 6-post shelter directly above the pump station to completely cover the top slab and hatch. They provide a large area of protection that can be used for sheltering emergency generators and other pieces of equipment. 6-post shelters are the biggest utility shelters we offer. 4-post shelters are a bit larger and can cover multiple pieces of equipment like odor control systems, small generators, or additional control devices. 2-post shelters are the smallest Romtec Utilities offers and are typically used when only the control panel needs weather protection. Shade and utility shelters are available in several sizes. Taking into account the unique weather conditions of each project helps to clarify what weather protection is needed and what equipment needs to be protected. It is often recommended to place control panels inside a NEMA enclosure for even more protection against infiltrating water and cold temperatures. When Romtec Utilities provides a pump station in this setting, control panels are often placed inside a building, in a shaded area, or beneath a utility shelter to prevent direct sunlight from overheating the control panel. The American Southwest, for example, has consistently high temperatures with clear skies and sun exposure – at least during the summer months. Some regions will be more exposed to certain weather conditions than others. Weather protection for electrical controls can be an important facet in pump station design.
