When the Data Center Isn’t the Problem — It’s Everything Around It

Sealcon Quick Reference Guides

The core of your data center might be humming along smoothly—but what about the infrastructure that keeps it alive?

Power distribution units, HVAC systems, backup batteries, and network cabinet fans often operate quietly in the background, but these systems are only as reliable as the components that hold them together. And when a supplier cuts corners on quality—or disappears when you need support—those “background” parts quickly become a real headache.

If you’re searching for a better solution for cable entry and strain relief, you’re not alone.

The Overlooked Challenge of Data Center Support Systems

Recently, a facility engineer came to us with a frustrating problem: their enclosure glands for cooling system sensors and backup power units were cracking under heat stress and failing to maintain their seal. On top of that, the existing solutions didn’t allow multiple small cables to pass through a single opening, creating cluttered junction boxes and added labor.

They didn’t need a total redesign, they just needed a cable gland that could do its job, last longer, and simplify their setup.
