What it removes in your conditions
Pick the temperature and humidity of your space. The capacity comes straight from the Thermoplus performance table for the SDAF-024.
Source: Thermoplus SDA performance table (70 to 90 °F, 40 to 70 % RH). 1 lb of water = 0.4536 L; a US pint of water weighs about 1.043 lb.
What it removes, in numbers
Its place in the SDA series (lb/h)
Capacity by temperature and humidity (lb/h)
Thermoplus SECARR SDA series cutsheet (REV 1), thermoplus.com. Every value checked on November 2, 2026. Capacity at the manufacturer's rating conditions; it changes with the actual temperature and humidity.
What does it cost to run?
Set your schedule. The math uses current Hydro-Québec rates and updates live.
Method: kW × hours/day × 30.4 days × run time × months. Rate G: 12.388 ¢/kWh up to 15,090 kWh a month, 9.534 ¢ after. Rate M: 6.292 ¢/kWh up to 210,000 kWh, 4.666 ¢ after (demand charge not included). Rate D: 7.065 ¢/kWh for the first 40 kWh a day, 11.142 ¢ after. Hydro-Québec rates in force since April 1, 2026, before tax; access fees and demand charges excluded. Water removed uses the rated capacity, so it is a maximum. Indicative estimate.
The first SDA with a scroll compressor and optional cooling
Scroll compressor
The SDAF-012 and 016 use a rotary compressor. From the 024 up, the series moves to scroll.
Dehumidifies and cools
Air-cooled option (CDS-044 condenser, up to 50 ft) or water-cooled (7.5 GPM at 85 °F).
More than the SDAF-016
12.3 lb/h at 82 °F and 60 % RH, about 134 litres a day.
Four voltages
208-230 V single or three-phase, 460 V and 575 V. At 575 V, minimum circuit ampacity is only 6 A.

Questions we hear often
What spaces is the SDA series built for?
Thermoplus describes it as a compact dehumidifier for light commercial and residential use: basements, storage rooms, mechanical rooms, archives and other spaces where humidity must stay low.
Can it be ducted?
Yes. The EC plenum fan is rated at 0.5 in of external static pressure, and the supply can leave from the top or the side per the cutsheet.
Why does capacity change with temperature?
Warmer, more humid air holds more water to remove. The Thermoplus cutsheet gives capacity from 70 to 90 °F and 40 to 70 % RH; the explorer above uses that table.
How do I know the SDAF-024 is big enough?
With a load calculation: room volume, infiltration, moisture sources and target humidity. We do it during the on-site estimate.
Why is there no price shown?
The price depends on voltage, options, ductwork, handling and access to the mechanical room. We price it after the on-site estimate, which is free.
