Data-driven guides to dehumidifier sizing, drainage, electrical requirements, controls, ducting, and model-specific questions.
A source-checked Sentinel HD55S Wi-Fi data sheet with electrical, drainage, ducting and dimensional specs, derived calculations, documented spec conflicts and buyer FAQs.
The AlorAir Sentinel HD55, HD55S Wi-Fi, and HDi65S occupy almost the same part of the crawl-space dehumidifier lineup. Their cabinet dimensions are essentially the same, and their AHAM capacities are only a couple of pints apart. The more useful buying differences are drainage and remote connectivity.
