85 pints/day · 15,000 cu ft · Built-in pump · Check current price

The Seaira Global WatchDog NXT85C is a North Carolina-built crawl space dehumidifier with an integrated condensate pump (the NXT85 is the gravity-drain version). Seaira rates it at 85 pints per day at AHAM conditions and publishes coverage as 15,000 cubic feet rather than a square-foot figure; at a 3 ft crawl space height that is roughly 5,000 sq ft, but that conversion is ours, not the manufacturer's.

The cabinet is 21.7 x 12 x 12 in., the same 12 x 12 cross-section as the Santa Fe Compact70, and weighs 60 lb. Published specs include 59 dBA, 185 CFM, a MERV-10 inlet filter, R32 refrigerant, all-aluminum coils, a 5.7 A draw and a 36 to 102°F operating range. Seaira also publishes the 65°F figure, 49 pints per day. The pump lifts 15 ft and ships with a 20 ft drain line.

Warranty is 5 years. We could not verify a price from an approved source: the Amazon listing was unavailable when we checked and the unit is not sold at Sylvane, so the spec table says 'Check current price'.

Built-in pump
MERV-10 filter standard
US-built with 5-year warranty

Cons

59 dBA, among the loudest published ratings here
COP 1.86 L/kWh (at 65°F/60%) is the lowest efficiency figure in the group
No verified price, and no Amazon or Sylvane listing in stock

Our take

The NXT85C is the pump unit to consider when the access opening only fits a 12 x 12 in. cabinet and you still need 85 pints of capacity. It is among the loudest units here at 59 dBA and its published COP of 1.86 L/kWh at 65°F is the lowest in the group, so expect higher running costs than the AlorAir or AprilAire units. Confirm price before buying.
