Reliable performance in all conditions.

Every eFRAME enclosure is engineered to perform in the harshest conditions. Built to withstand winds over 135 mph and certified to UL 2200 FTPP standards, your investment is protected against extreme weather events. UL 142/ULC-compliant subbase tanks mean faster permitting and smoother installations, while advanced CFD analysis ensures your generators maintain peak efficiency even under stress.

Accessible for easy servicing.

Our custom-designed enclosures provide maintenance teams with instant access to the engine and radiator, eliminating the need to disconnect. Wide-door access and generous workspace around the generator enables technicians to diagnose problems quickly, work more safely, and complete repairs efficiently, keeping your facility powered and productive.

Modularity means no disruption.

Our modular design, featuring removable roof panels, helps streamline maintenance. Service teams can complete work faster with overhead crane access, dramatically reducing labor costs and minimizing the time backup power is offline. That results in predictable maintenance schedules that save you time and money.

Installation that’s easy as 1-2-3.

Complex installations eat budgets and lead to project delays. Our eFRAME enclosures are engineered for straightforward deployment, which enables you to get your backup power online faster.

It’s a step-by-step process:

  1. Set the tank

  2. Mount the generator

  3. Position the enclosure

And, done! It’s as easy as that to ensure reliable backup power delivered on schedule and within budget.
