Commercial units are built for 24/7 restoration or warehouse duty. The primary technical metric is Low Grain Refrigerant (LGR) technology, which allows the unit to remove moisture even in dry conditions below 40% RH, where standard home units fail. Look for an airflow rating of 250-400 CFM and a high-impact rotomolded housing. Essential features include an on-board hour meter for maintenance tracking, a heavy-duty internal pump, and ductable intake/exhaust for targeted drying in construction or flood-damaged environments.
