Which NEMA Type 4x Rated Enclosure is Best for Corrosive Environments?

April 1, 2024

When planning a large or small scale electrical project, it can be easy to overlook the importance of choosing the proper housing for electronic controls. Whether inside or outside, the external surroundings need to be considered in order to choose the right material and security features for your enclosure. Some users might be tempted to just use any enclosure. But selecting an enclosure with the necessary protection and insulation from its external surroundings is an integral part of any operation requiring electronic controls. This is particularly important in harsh and corrosive environments.

Allied Moulded Products can help you take the guesswork out of your electrical enclosure needs. A true American story with humble beginnings in rural Ohio, Allied Moulded Products has led the way for nonmetallic electrical boxes and enclosures for over 65 years. Allied Moulded has found its niche with a fiberglass-reinforced polyester (FRP) material. Although messy and difficult to handle, Allied Moulded’s team of experts has leveraged the extraordinary traits of FRP to create a specialized formula that meets the demands of multiple industries. Their proprietary ULTRAGUARD formulation provides maximum protection against the elements and extends the life of the enclosure, even in extreme sun exposure.

When asked about their highest-rated products in the market, Jeff Parker, Director of Sales and Marketing at Allied Moulded, pointed out that although they manufacture and distribute several different types of enclosures, one series stands above the rest as an exceptional choice. “Our Ultraline series of enclosures offer a robust defense against the elements along with a modern design. They are a compilation of the best features our AM Series had to offer, along with innovations to address challenges and requirements our team was finding across all sectors in the field. Ultraline enclosures give the end user the ultimate protection for their equipment with a sleek and visually appealing design. They’re extremely durable, non-corrosive, and built to last.”

Ultraline was specifically engineered to keep water and dust out, retaining a NEMA Type 4X rating. The base and cover feature an advanced tongue and groove design that works in conjunction with a polyurethane gasket system to create an exceptional seal, regardless of the latching mechanism. Further, Ultraline enclosures were designed with a unique molded-in hinge and latch keeper which eliminates the need to drill holes for latches and hinges. Allied Moulded enclosures are routinely tested in UL-approved lab facilities to ensure contractors are getting a quality product to keep their electrical components safe.

Ultraline’s innovative designs — paired with the excellent resistive properties to corrosive chemicals and extreme temperatures of the fiberglass material — make Ultraline enclosures a brilliant choice for environments where high temperatures, moisture, and direct sunlight are concerns. These premium enclosures are well-suited for coastal applications including marinas, watersheds, water treatment facilities, and pumping stations.

Regardless of the industry, when dealing with specialty projects and high-dollar equipment, visual appeal of an enclosure is often highly valued. The sleek and modern look of Ultraline enclosures — along with their extreme durability — make them an enticing option for any contractor. They feature a flush lid to base design, raised covers, beveled corners, and smooth edges — a look that integrates well with a variety of applications. When optimum visibility is needed inside the enclosure without opening the cover, Ultraline series enclosures are also available with a crystal-clear full polycarbonate cover or viewing window.

In addition to the features of Ultraline, Jeff touched on the outlook of Allied and the markets they supply. “The future for our industry is bright. We’re seeing an influx of quoting activity within all industries we serve, and Ultraline is an easy solution for contractors looking for dependability and innovation in an enclosure. Allied Moulded is positioned well to support increased demand in the market. We’ve made many strides in processes and improved capacities over the past few years, and we’re always looking for ways to improve or expand our current product offerings.”

Allied Moulded’s Ultraline series of enclosures are available in a variety of sizes to meet the needs of most applications and give the user the ultimate in design, safety, and versatility.
