Emerson has launched its Appleton Contender 4/4X Series control stations and tumbler switches for processing industries operating in harsh environments
Processing hazardous materials requires reliable power distribution and controls to operate efficiently, yet these electrical control devices are challenged by exposure to harsh weather, corrosion, moisture, and other foreign materials.
The Appleton Contender 4/4X Series control stations and tumbler switches feature a superior gasketed design offering Type 4, 4X, 12 and IP66 ingress protection. This introduction brings more cost-efficiency, performance, and reliability to oil and gas, wastewater, grain milling, and other processing industries operating in harsh environments including Class I, Division 2 and Zone 2, Class II, and Class III locations.
"Explosionproof, Division 1 rated control stations and tumbler switches lack sufficient ingress protection, leading to device failure, high maintenance costs, and more frequent replacements, especially when exposed to corrosive elements," said Donald LaCombe, senior product marketing specialist for Emerson. “Leveraging a gasketed design and a superior material finish, the Appleton Contender 4/4X Series offers a protective barrier from harmful corrosion and prolonged exposure to the elements, adding value and lowering total cost of ownership."
Unlike Explosionproof, Division 1 rated control stations and tumbler switches, the Appleton Contender 4/4X Series utilises a gasketed cover and devices as well as O-rings supplied on captive stainless steel screws. Additionally, this series comes standard with iron back boxes utilising the Appleton patented triple-coat finish, in addition to a durable epoxy powder coat finish supplied on device covers and optional aluminum back boxes for Type 4X rating. These design enhancements prevent ingress that leads to device failure and component corrosion over time.
