Stephanie Trent, CEORather than simply offering enclosures around standard dimensions, Modutek International develops each solution around the customer’s site, footprint and operational requirements. Customization also extends beyond technical specifications. Many of its enclosures serve architecturally attractive buildings, with designs tailored to complement their surroundings.
Its in-house mechanical and electrical engineering teams become involved at the specification stage, helping engineering firms define requirements for a particular site before carrying the solution through design, fabrication and testing. This end-to-end approach also allows customers to consolidate major components under a single purchase order, reducing vendors and procurement handoffs.
Its engineering team also provides PE-stamped drawings, wind-loading analysis and earthquake-zone ratings where required, giving customers engineering support from specification through production. Beyond engineering, the company manufactures, tests and integrates complete power packages, including UL-listed enclosures, circuit breaker cabinets, load banks, UL142 fuel tanks and UL2085 fuel tanks.
Engineering beyond the Standard
Modutek International handles fabrication from raw coil steel through finished enclosure, using lasers, press brakes, punches, turrets and plasma tables. Because it stamps, bends and coats metal in-house, the company is not constrained by standard vendor dimensions and can build enclosures to virtually any required size.

We’re expecting significant growth over the next few years, and our expansion projects are designed to support that demand.
Many of its modular packages share common components, including wall panels, roof panels and subpanel sections, enabling efficient production while maintaining design flexibility. Modutek International demonstrated that flexibility on a project located in St. Louis, where the customer needed substantial fuel capacity within a highly constrained footprint. Rather than forcing the site to accommodate a standard configuration, it engineered a taller-than-standard UL2085 tank and secured UL approval for the design.
Its 78-inch-tall sub-base tanks can also accommodate projects requiring 20,000 gallons of fuel within footprints as constrained as 36 feet in length.
Infrastructure Built to Size
Modutek International’s integrated approach is supported by a 140,000-square-foot high-bay facility with multiple heavy-lift overhead cranes. The capacity allows it to fabricate and move oversized enclosures and modular power packages, including multi-generator and switchgear configurations, that require substantial scale.
The rail-served facility supports the movement of large equipment, with packages manufactured in sections for transportation and final assembly at the customer’s site. For example, large power packages comprising four generators and a switchgear enclosure are manufactured in sections and transported to the customer’s site for final assembly.
A Legacy of Engineering Expertise
Modutek International’s roots stretch back to 1986, bringing decades of engineering and manufacturing experience reflected in the relationships built through years of serving demanding projects.
Building on that foundation, Modutek International is undertaking multiple facility expansions to accommodate projects already booked for the coming years, particularly as demand from the data center market increases.
“We’re expecting significant growth over the next few years, and our expansion projects are designed to support that demand,” says Stephanie Trent, CEO.
As power infrastructure projects become more complex, Modutek International is expanding its capacity without changing its core approach; helping customers define site-specific requirements, engineer the solution and carry it through integrated manufacturing and testing.
Specification Discipline for Custom Power Enclosures
A power enclosure can satisfy equipment dimensions on paper and still create costly trouble at the site. Rooflines may conflict with surrounding architecture, while sound limits can tighten after layout approval. Access paths may also shrink once civil work advances, and generator packages carry structural and electrical dependencies that leave little room for late correction. Procurement teams need more than a fabricator that can build from a finished drawing. They need a manufacturer able to engage while the specification is still being shaped.
Early engineering depth is the clearest dividing line. Mechanical loads and electrical interfaces must be reconciled with the available footprint before steel is cut. Wind ratings or seismic requirements may demand stamped drawings and site-specific analysis. Existing facilities create another layer of constraint because equipment often has to fit around walls and service clearances while meeting fixed fuel-capacity requirements. A manufacturer with in-house mechanical and electrical engineers can test those conditions against the proposed package instead of passing unresolved questions among outside firms.
Dimensional flexibility matters just as much. Standard modules may lower quoting effort, yet they can force the buyer to redesign the site around the enclosure. That tradeoff becomes unacceptable when a project needs greater fuel volume within a restricted footprint or when several generator sections must connect to a switchgear room. Buyers should examine how much fabrication is controlled internally, including metal forming and coating. Direct control over these processes gives the manufacturer more freedom to alter height or length while keeping mating sections aligned.
“Modutek International brings enclosure fabrication, fuel systems, electrical assemblies and package testing under one purchase order.”
Package responsibility presents another pressure point, though it should not be reduced to convenience. Multiple purchase orders create interface risk between tanks and enclosures or between load banks and breaker cabinets. Testing responsibility may also become fragmented. A single-source package can simplify accountability when one manufacturer designs the enclosure and integrates the major equipment. Its responsibility should extend through assembled-system verification. That model is most credible when backed by lifting capacity and indoor handling space, as well as transport access suited to large sectional builds.
Appearance also deserves attention on projects tied to hospitals, data centers or prominent commercial sites. An enclosure may need parapet walls, gutters, coordinated finishes or a roof profile that fits the facility rather than resembling a temporary container. Acoustic treatment and environmental protection remain technical requirements, but exterior form can influence permitting and owner acceptance. The strongest suppliers treat those constraints as part of the design brief rather than cosmetic changes introduced after fabrication.
Modutek International fits this buying logic through an integrated engineering and manufacturing model. Its portfolio includes weather-protective generator enclosures, electrical room enclosures, UL-listed fuel tanks, load banks and circuit breaker assemblies. Its team supports early specification work, develops custom dimensions and produces PE-stamped drawings when required.
The company fabricates metal components in-house and handles large sectional packages through a rail-served heavy-lift facility. It brings enclosure fabrication, fuel systems, electrical assemblies and package testing under one purchase order. For projects constrained by footprint, site architecture or package interfaces, that breadth warrants serious consideration.

Q1
What Does Enclosures and Electrical Assemblies Manufacturer Work Include?
Manufacturers of enclosures and electrical assemblies design and construct protective housings and complete electrical packages according to the requirements of the equipment, the site, and the way it is to be operated. Such work encompasses generator enclosures, electrical rooms, circuit breaker cabinets, fuel tanks, load banks, and other similar assemblies. The category also includes engineering, fabrication, integration, and testing, enabling projects to take into account dimensions, the interfaces of power equipment, environmental conditions, and site restrictions all within a single coordinated package. This in turn helps to coordinate the physical design, the electrical interfaces, and the testing requirements before the equipment is delivered to the site.
Q2
How Do Custom Enclosure And Electrical Assembly Solutions Support Projects?
Customization matters when standard enclosure dimensions do not fit the available footprint or operating requirements. Enclosures and Electrical Assemblies Manufacturer solutions can be developed around site dimensions, equipment layouts, fuel capacity, structural needs, and architectural requirements. Depending on the project, engineering may include wind-loading analysis, seismic ratings, stamped drawings, and custom metal fabrication. This approach can reduce the need to redesign a site around a standard enclosure and can clarify requirements earlier in project planning.
Q3
How Does Modutek International Approach Enclosures and Electrical Assemblies Manufacturer Projects?
Modutek International brings mechanical and electrical engineering into the specification stage before fabrication begins. It develops custom enclosure dimensions and provides PE-stamped drawings, wind-loading analysis, and earthquake-zone ratings when required. Its capabilities also include UL-listed enclosures, circuit breaker cabinets, load banks, UL142 and UL2085 fuel tanks, and complete power-package integration. These capabilities allow Enclosures and Electrical Assemblies Manufacturer projects to move from early requirements through design, fabrication, testing, and delivery.
Q4
What Manufacturing Capabilities Matter In Custom Enclosure Work?
Because they carry out the fabrication in-house, providers of enclosures and electrical assemblies are able to have greater control over dimensions and the fit of the components. Modutek International carries out the process starting with raw coil steel and ending with finished enclosures, using lasers, press brakes, punches, turrets and plasma tables. It also performs stamping, bending and internal coating of the metal. This level of control allows for custom sizes to be provided when a project calls for a taller enclosure, a smaller footprint or coordinated sections for a larger power package.
Q5
How Do Providers Handle Large Power Packages?
Large projects can require equipment to be fabricated in sections, moved safely, and assembled at the final site. Enclosures and Electrical Assemblies Manufacturer providers with suitable handling and transport capabilities can support this process alongside engineering and fabrication. Modutek International operates a 140,000-square-foot high-bay facility with multiple heavy-lift overhead cranes and rail access. Its packages can include multi-generator and switchgear configurations, with sections transported for final assembly at the customer’s site.
Q6
What Should Buyers Evaluate When Selecting An Enclosures and Electrical Assemblies Manufacturer?
The assessment should include considerations of engineering involvement, dimensional flexibility, fabrication control, testing responsibility, and the capability of managing multiple components as a single package. In addition, providers of enclosures and electrical assemblies may also have to deal with fuel capacity, structural loads, sound limits, service clearances, and architectural appearance. Modutek International carries out the fabrication of enclosures, provides fuel systems, supplies electrical assemblies, and performs package testing all under a single purchase order; the company's origins go back to 1986, and the current facility expansions are meant to accommodate projects that are already scheduled for the coming years.
