Split dehumidifier · 510 pints/day
VKIN UCDA-D510DCT Ducted split dehumidifier for large flower rooms
The larger split — 510 pints/day, or 528 in constant-temperature mode — on the same architecture as the D360: separated indoor and outdoor units, three-pipe heat recovery, and no compressor heat dumped into the room. The efficiency actually improves with size at 9.2 pints/kWh.
Where it fits
Built for these rooms.
The bigger split: 46% more water removal than the D360DCT, at better efficiency per kWh.
Runs from its wired controller or a standard 24V thermostat, alongside the cooling you already have.
The compressor sits outdoors, so pulling 500+ pints a day doesn’t add compressor heat to the room.
Split design
Water out. Heat outside.
- Pull water out indoors
The ducted indoor cabinet draws room air across its coil and condenses the moisture out.
- Keep the heat outside
The compressor and condenser sit in the outdoor unit, so their heat is rejected outdoors, not into your flower room.
- Hold the room
Three-pipe heat recovery and a constant-temperature mode remove water without swinging room temperature.

Questions
UCDA-D510DCT FAQ
How much water does the UCDA-D510DCT remove?
510 pints per day (21.3 pints/hour) at 80°F and 60% RH, 326 pints per day at 75°F and 50% RH, and 153 pints per day at 65°F and 50% RH. Constant-temperature mode removes 528 pints per day at 80°F and 60% RH.
D510DCT or D360DCT?
Same architecture. The D510DCT removes 510 vs 350 pints per day, moves 1,150 vs 800 CFM, and is slightly more efficient at 9.2 vs 8.6 pints/kWh.
What power and line set does it need?
Single-phase 208–277V, 60 Hz, drawing 2,300 W at 10.2 A. Refrigerant lines are 3/8″, 1/2″ and 5/8″, up to 100 ft long with 33 ft of vertical difference.
How is it controlled?
With the included wired controller, or with a 24V thermostat or humidistat signal.
