Janitori carries commercial dehumidifiers from Ebac, XPOWER and Dapper Supply for restoration crews, warehouses, basements and facilities that need to pull moisture out of the air on a schedule, not on a hope. Compare low grain refrigerant (LGR), refrigerant and desiccant designs below, then match capacity and drainage to the space.

Commercial Dehumidifiers

What Is the Difference Between LGR and Desiccant Commercial Dehumidifiers?

LGR (low grain refrigerant) units use a refrigerant cycle tuned to keep pulling moisture as the air dries, while desiccant units adsorb moisture on a silica gel rotor and are rated for cooler, drier conditions. The XPOWER XD-85L2 and XD-165L are LGR units with an operating range of 33°F to 105°F; the Ebac DD400 uses a patented PPS rotor with 82% active silica gel and a PTC heater.

Refrigerant models fit most occupied spaces and restoration jobs. Desiccant models are the usual pick for cold or very dry spaces where a refrigerant coil would struggle. See also air movers to speed drying and air scrubbers to filter the air during a job.

How Do You Size a Commercial Dehumidifier?

Match the rated pints per day to the space, and compare units at the same test point. AHAM ratings are stated at 80°F and 60% RH; saturation ratings (90°F, 90% RH) read higher for the same machine. The XPOWER XD-85L2 is rated 85 pints/day at AHAM and 145 at saturation, and the XD-165L is rated 165 at AHAM and 280 at saturation.

The Dapper Supply 190-pint unit lists 15,000 sq ft of coverage with 700 CFM airflow, a built-in pump and a 2-gallon tank. Larger or colder spaces move up to bigger LGR or desiccant units, and several smaller units can be staged where one machine cannot reach.

Not sure what size you need? The dehumidifier size calculator gives the pints per day for a room (ENERGY STAR) or a water-damage job (IICRC factors) and lists the units here that cover it.

Which Drainage Option Should You Choose?

Choose a built-in pump when the unit will run unattended, and a gravity hose or manual tank only when a floor drain is close. XPOWER LGR models include an auto purge pump and drainage hose that empties the reservoir when it fills, and the Dapper Supply units add a pump that lifts water 16.4 ft plus a 3.28 ft gravity hose.

Check the voltage on the listing before ordering: the Ebac range includes 115V, 230V and 3-phase 230V/460V models. Browse the full Ebac, XPOWER and Dapper Supply lines, then compare specs on each product page.
