Modular Switchgear Enclosure for High-Heat Manufacturing Environment

The Challenge: Protecting Critical Equipment with Minimal Downtime

At the St. Louis location of a global specialty chemical manufacturer, switchgear equipment played a vital role in daily operations. However, the equipment needed protection from extreme heat and exposure in an active industrial environment. The client required a fast, effective way to house the gear in a temperature-controlled, low-maintenance enclosure, also without halting production.

The Solution: Custom Modular Construction from Henges Commercial Contracting

Henges Commercial Contracting, the interiors division of Jay Henges Enterprises, partnered with Porta-King to design and build a fully enclosed modular room to house the switchgear. The 10' x 20' x 10' structure was constructed using Porta-King's modular building system, chosen for its speed of installation and durability in industrial settings.

The exterior featured a painted steel surface for enhanced durability, while the interior walls were finished with smooth fiberglass reinforced plastic (FRP)—a material selected for its easy-clean surface and exceptional resistance to moisture, impact, and corrosion. Both surfaces were laminated to a solid insulating core to deliver thermal protection essential for sensitive electrical equipment.

Key Benefits:

  • Thermal Protection: The insulated wall system ensures consistent internal temperatures, extending the life of the switchgear equipment.
  • Durability and Cleanability: FRP interior panels and painted steel exterior walls offer long-term performance with virtually no maintenance required.
  • Fast, Efficient Installation: Modular construction minimized on-site disruption, allowing production to continue uninterrupted.
  • Turnkey Execution: From design to installation, the Henges team managed the entire project using in-house carpenters, ensuring quality and speed.

Results: A Clean, Controlled, and Low-Maintenance Solution

With minimal disruption to manufacturing operations, Henges Commercial Contracting delivered a high-performance modular enclosure that checked every box: durable, insulated, and easy to maintain. The new structure provides a secure environment for critical electrical systems while supporting the client’s ongoing efficiency and reliability goals.
