Anden A711 V3 Dehumidifier — 705 Pints/Day

Commercial facilities wired for 277V need dehumidification that runs on their existing power without step-down transformers or extra circuits. The Anden A711 V3 removes up to 705 pints per day (at 80°F, 60% RH) and moves 1,800 CFM on 277V single-phase power, drawing just 13.7 amps at rated conditions.

The A711 V3 is built around M-CORR (Multi-Coil Refrigerant Recovery), patented technology developed by the engineers behind Quest. It optimizes multiple coils and recycles refrigerant through the system, which raises efficiency and extends operation across a broader dewpoint range than a standard two-coil dehumidifier. In late flower, when transpiration peaks and many units lose time to defrost cycles, the A711 V3 keeps pulling water. That helps hold humidity and VPD steady to support plant health and crop quality.

The A711 V3 sticks to the essentials growers rely on and keeps upfront cost in check. Integrated suspension points, a ductable cabinet, a removable cord for hardwiring, a digital interface with onboard error codes, a 24VAC terminal block for external controllers, and a removable service panel keep installation and maintenance simple. For 208-240V facilities, the same platform is available as the Anden A711 V1.

Features

⚡
Native 277V Power

Runs on 277V single-phase service at 13.7 amps with no step-down transformer required.

💧
705 Pints Per Day

Handles heavy moisture loads in large flower rooms, with 7.6 pints/kWh efficiency at rated conditions.

❄️
M-CORR Technology

Multi-coil refrigerant recovery extends the dewpoint range and cuts time lost to defrost.

🏗️
Hang, Stand, or Duct

Suspend overhead, place on the floor, or duct from an adjacent room. The cord is removable for hardwiring.

🎛️
Digital and Remote Control

Set RH onboard, read error codes, or connect an external controller through the 24VAC terminal block.

🔧
Easy Filters and Service

Self-sealing MERV-13 filters pull straight out, and a removable side panel opens up in-place service.

Installation Options

No two cultivation rooms are laid out the same. The Anden A711 V3 supports three installation methods, so you can fit it to your space instead of redesigning the room around it.

Anden A711 V3 Dehumidifier suspended from ceiling with threaded rods
Suspended

Mounts above the lights to save floor space without blocking light.

  • Built-in suspension points accept 3/8" threaded rod
  • Pulls in humid air and returns dry air to the room
Anden A711 V3 Dehumidifier freestanding on leveling feet with condensate drain
Freestanding

Sits on the floor inside the cultivation room.

  • Ideal where overhead mounting isn't possible
  • Included adjustable feet level the unit on flat surfaces
Anden A711 V3 Dehumidifier with inlet and outlet duct connections
Inlet and Outlet Ducted

Installs in a separate room and connects to the grow space through ducts.

  • Ideal for grows with no space for an in-room unit
  • Can be suspended or installed at ground level

Warranty

The Anden A711 V3 Dehumidifier is covered by a 3-year limited manufacturer warranty from the original date of purchase.

Frequently Asked Questions

What's the difference between the A711 V3 and the A711 V1? +

Both models share the same 705 pints/day capacity, 1,800 CFM airflow, M-CORR coil design, and cabinet. The A711 V3 is built for 277V single-phase power with an MCA of 21 A and MOP of 30 A. The A711 V1 runs on 208-240V. Choose the model that matches the electrical service in your facility.

What receptacle and circuit does the A711 V3 need? +

The A711 V3 ships with a 6 ft. NEMA L7 twist-lock cord and runs on a 277V single-phase circuit sized to its 21 A MCA and 30 A MOP. A GFCI-protected circuit is recommended, and the unit should never be used with an extension cord. The cord can also be removed for hardwiring with a field-installed disconnect.

How many A711 V3 units can I run from one controller? +

Up to six units can be daisy-chained to a single external control. Because every unit starts at once, monitor supply voltage at startup: on 277V models it should not drop below 250V. If it does, add controllers or use time-delay relays to stagger startup.

Can I daisy-chain the A711 V3 with older Anden A710 units? +

Yes, but the A711 must be placed last in the chain. Wiring it ahead of A710 units can damage the units downstream. Refer to the daisy chain diagrams in the installation manual before wiring a mixed setup.

Which external controllers work with the A711 V3? +

Anden's DEH 3000R and QA76 controls connect directly to the 24VAC terminal block, as does any dry-contact controller rated for a 24VAC signal, such as TrolMaster. After wiring, press the Terminal Control button so the unit follows the external signal instead of its internal RH sensor.

What do I need to hang or duct the A711 V3? +

To hang the unit, you'll need four 3/8" threaded rods and four 3/8" jam nuts (not included), with a maximum rod length of 6 ft. For ducted installs, use the optional intake and exhaust duct kits with at least two 15" round ducts, and keep static pressure under 0.25" WG.

What do the error codes on the display mean? +

The onboard display shows codes E1 through E9 to flag issues such as a sensor fault, low dewpoint, low refrigerant, a tripped float switch, or high-pressure cut-out. Many codes clear on their own once conditions return to range. Codes like E3 (low refrigerant) and E4 (float switch tripped) require service. The full error code table is in the installation manual.

What does the A711 V3 warranty cover? +

The 3-year limited warranty includes 1 year of full coverage, plus 2 additional years of parts replacement on the condenser, evaporator, and compressor. Running the unit without its MERV-13 filters, or with a lower-grade filter, voids the warranty.
