ALORAIR specializes in serious moisture control, and the Sentinel HD90 is built for spaces that demand it. This is a commercial-grade unit designed for the persistent dampness of large basements, expansive crawl spaces, and busy job sites. Its purpose is straightforward: to remove a massive amount of water from the air, reliably and without fuss.

With a saturation capacity of 198 pints per day, it can handle areas up to 2,600 square feet. In practice, that means it can transform a musty, damp basement into a dry, usable storage or living area within a day. The automatic defrost function is key for cooler environments, allowing it to operate effectively without icing up. While compact and fitted with handles for portability, this is a powerful appliance. You’ll hear it working, and you’ll feel a steady stream of warm, dry air coming out.

It’s a straightforward tool that excels at its primary job. For a flooded restoration project, a chronically wet warehouse, or a finished basement that needs climate control, the Sentinel HD90 delivers industrial-scale drying. Just be prepared for its substantial output and ensure you have a drain hose or a large reservoir for continuous operation.
