APO Fiberglass Covers & NEMA 4X Enclosures

When it comes to industrial operations, particularly in wet or corrosive environments, the performance of electrical systems responsible for the safe operation of computers and automated machinery is critical. Safeguard your assets from the elements with APO NEMA 4X electrical enclosures with fiberglass covers from Vynckier Enclosure Systems.

Vynckier is a leading manufacturer of high-performance electrical enclosure systems for demanding indoor and outdoor applications. From basic environmental protection to hazardous or corrosive applications, our UL-, IP-, and NEMA-rated electrical enclosure solutions have you covered.

Benefits of APO Enclosure Systems

An enclosure is a cabinet for electrical or electronic equipment to mount circuits, switches, knobs, and displays. Occasionally called a housing or box, it prevents electrical shock to equipment users and protects contents from the environment. Additional advantages of the Vynckier APO NEMA 4X enclosure with fiberglass cover includes:

  • Maintenance-free
  • Corrosion-resistant
  • Flame retardant, self-extinguishing
  • Protects against water, oils, coolants, dirt, and dust
  • Prevents incidental contact with internal equipment
  • Keeps the enclosed equipment in good and functioning condition

APO NEMA modular fiberglass electrical enclosures from Vynckier are designed for use as insulated electrical junction boxes, terminal wiring boxes, instrument housings, and electrical control enclosures in highly corrosive environments.

APO Enclosure Construction & Design

Vynckier offers an extensive range of APO NEMA 4X enclosures with fiberglass covers, which help protect electrical components from damage. Constructed from high-quality materials using precision manufacturing methods, they stand up to the harshest operating environments.

  • Sizes range from 7 x 6 to 24 x 24
  • Bases and opaque covers are constructed from fiberglass-reinforced polyester, or FRP
  • Transparent covers are made from transparent polycarbonate
  • All enclosures can be easily modified to customer specifications
  • Gaskets are made from continuously poured polyurethane foam
  • Brass M4 threaded inserts are factory installed for mounting plate attachment
  • 4 to 6 bosses suitable for M6 threaded inserts are molded into the base, dependent on enclosure size
  • Maintain UL / CSA Type 4x with up to 5 extension collars
  • Available with hole locations ready to be punched

Applications for APO Enclosure

All APO series enclosure systems have a 4X rating from NEMA, or the National Electrical Manufacturers Association. A NEMA 4X rating means the enclosure has been rigorously tested to ensure optimum performance in outdoor use and offers a superior level of protection against corrosion and extreme conditions. A NEMA 4X rating makes Vynckier APO series enclosures with fiberglass covers perfect for a variety of applications.

  • Indoor or outdoor use
  • Offshore operations
  • Protection against windblown dust and rain
  • Hygienic environments
  • Protection from splashing water and hose-directed water
  • Hazardous conditions

Bases and opaque covers are made from hot compression-molded halogen-free, self-extinguishing fiberglass-reinforced polyester, or FRP. Its characteristics include smooth internal surfaces, heightened thermal insulation capabilities, high-temperature resistance, and robust anti-corrosion properties in a lightweight, high-strength package. FRP can withstand continuous temperatures up to 302F degrees Fahrenheit, or 70 degrees Celsius, and momentary exposure to degrees Fahrenheit, or 150 degrees Celsius.

Client-Tailored Electrical Enclosure System Solutions

If you regularly buy standard electrical enclosures and boxes, you know many options are available. However, standard or off-the-shelf products aren’t always best. Vynckier offers an array of services tailored to help clients obtain the right electrical enclosure system for their application.

Modifications Services

Another common modification is special paints and finishes, which can be beneficial for branding purposes. Standard enclosures tend to be basic gray colors that blend into their surroundings and go unnoticed. Vynckier’s Imprint & Paint Shop services give the option for special colors, logo identification, and labeling, and provide limitless options for a unique appearance.

Working With Vynckier

At Vynckier, client satisfaction is our utmost priority. We know that a subpar electrical enclosure system negatively impacts on-the-job performance.

That is why our staff approaches each order with a quality-first mindset. Material is acquired from reputable suppliers, and compliance is verified upon arrival. Quality control personnel use precise testing and inspection equipment to ensure every electrical enclosure produced surpasses customer specifications. All orders are audited for accuracy before shipment.
