If you have a crawlspace 1,200 sq. ft. or less most people will use a “compact” model with a condensate pump when encapsulating. If your crawlspace is 2,000 sq. ft. or more you would want a larger model. Such as, the Aprilaire 1850 with a condensate pump sold separately. Seaira Global have released the Watchdog NXT85c with a built in condensate pump. Both these brands of dehumidifiers have a 5 year warranty program too.
