Powder Coated Generator Enclosures

Durable Protection for Custom Mobile Generators

PowerTech generators are designed to provide dependable power in demanding mobile and commercial environments. Protecting the fabricated metal components and enclosures is an important part of producing a generator that can withstand moisture, sunlight, road debris, abrasion, and regular use.

PowerTech works with an experienced powder coating provider to apply durable, high-quality finishes to our generator enclosures and fabricated components. Each coating is selected and applied according to the requirements of the generator and its intended application.  Once the coated components are returned to our Central Florida facility, they are carefully inspected by the PowerTech team before moving into final assembly.

Why PowerTech Uses Powder Coating

Powder coating provides a strong and consistent finish that offers advantages over many conventional liquid paints. The powder is applied to prepared metal surfaces and cured to create a durable protective layer.

This process helps protect generator enclosures and fabricated components while also providing the clean, professional appearance expected from a PowerTech generator.

Corrosion Resistance

Mobile generators are frequently exposed to humidity, rain, road spray, salt, and other environmental conditions. Powder coating creates a protective barrier that helps prevent moisture and corrosive materials from reaching the metal beneath the finish.

This protection is especially valuable for generators installed in coastal environments, mobile medical vehicles, food trucks, emergency response vehicles, and other equipment that regularly operates outdoors.

Resistance to Chips and Scratches

Generator enclosures can encounter road debris, tools, equipment, vibration, and repeated handling during installation and service. A properly applied powder coating provides greater resistance to chipping, scratching, and abrasion.

The durable finish helps protect the enclosure and maintain its appearance throughout the generator’s service life.

Resistance to Chips and Scratches

Generators installed on vehicles and outdoor equipment may experience extended exposure to sunlight. Powder coating helps protect the enclosure from fading and surface deterioration caused by ultraviolet exposure.

The exact level of UV resistance depends on the coating selected for the application and the conditions in which the generator will operate.

Chemical Resistance

Commercial and industrial generators may be exposed to fuel, cleaning products, oils, and other chemicals. Powder coated surfaces provide an additional layer of protection against many substances commonly encountered during operation and maintenance.

Professional Appearance

Performance and durability remain our priorities, but appearance also matters. Powder coating creates a smooth, consistent finish that complements the quality and craftsmanship of the completed generator.

Preparing Components for Powder Coating

A durable finish begins with proper surface preparation. Before coating, fabricated metal components must be cleaned and prepared to remove contaminants that could interfere with adhesion or create imperfections in the finished surface.

The specific preparation process may vary based on the metal, component, finish, and intended operating environment. Proper preparation helps the coating bond evenly to the surface and contributes to long term durability.

Professional Powder Application and Curing

After surface preparation, powder is applied to the fabricated components using specialized equipment. The coating is distributed across the surface to achieve even coverage, including edges, corners, and other areas that require protection.  The components are then cured under controlled conditions. During curing, the powder forms a continuous protective finish that bonds to the metal surface.  PowerTech relies on an experienced coating partner with the equipment and knowledge necessary to produce a consistent finish for our fabricated generator components.

PowerTech Quality Inspection

Outsourcing the application of the powder coating does not mean outsourcing our commitment to quality. PowerTech establishes the requirements for our coated components and inspects them before they are approved for generator assembly.

Our team evaluates coated components for:
  • Consistent color and appearance
  • Even coverage across the component
  • Proper coating adhesion
  • Surface flaws or imperfections
  • Damage that may have occurred during handling or transportation
  • Proper fit and compatibility with the generator assembly

Components that do not meet PowerTech’s requirements are addressed before they proceed to final assembly.

From Fabrication to Final Assembly

Powder coating is one part of PowerTech’s complete generator fabrication and assembly process. Our team designs and fabricates components to meet the space, airflow, sound, service access, and installation requirements of each generator application.

After the coated components pass inspection, they move into the assembly process. Our technicians carefully install the enclosure, sound attenuation materials, access panels, ventilation components, controls, and other features required by the generator design.

This coordinated process allows PowerTech to deliver custom generator solutions without sacrificing durability, serviceability, or appearance.

Powder Coating for Custom Generator Applications

PowerTech manufactures generators for specialized vehicles and commercial equipment where standard, one size fits all generator packages may not meet the application’s requirements.

Our powder coated enclosures can support generators used in applications such as:

Every application presents different challenges. PowerTech considers the generator’s installation location, operating environment, ventilation requirements, service access, and overall configuration when developing the finished system.
