Industrial Humidity Control for Maximum Yields
In commercial cultivation, moisture management is the difference between a bumper crop and crop failure. Anden builds equipment that treats humidity control as a precise science, not an afterthought. By maintaining stable setpoints during the lights-off cycle, you prevent the dew point spikes that lead to Botrytis (bud rot) and powdery mildew.
The Science of VPD & VLGR Technology
An Anden dehumidifier does more than remove water; it allows you to steer plant metabolism. By optimizing the humidity relative to temperature (VPD), you encourage ideal stomatal opening and nutrient uptake.
-
Variable-Speed Performance: Models like the
Anden A320V1 utilize VLGR (Variable Low Grain Refrigerant) technology to modulate performance, saving energy while holding conditions tight.
-
Grow-Optimized Durability: While standard HVAC units corrode, Anden units feature specialized coatings to resist the humid, rich environment of a grow room.
-
Steam Humidification: For the vegetative stage where moisture is vital, the
Anden AS150 injects sterile steam to keep seedlings and clones thriving without wetting the canopy.
Sizing Your Dehumidification System
Choosing the right unit requires calculating your total water input. A properly sized system runs efficiently without rapid cycling, extending the life of the compressor.
-
Dry Rooms & Small Tents: For spaces requiring up to 70-100 pints of removal, the
Anden A70 offers a compact footprint that can be suspended to save floor space.
-
Commercial Flowering Rooms: Large facilities demand the
Anden A710V1, a beast capability of removing over 700 pints per day to handle massive transpiration loads.
-
Automation Ready: Pair your dehumidifier with an
Environmental Controller to automate humidity spikes during the critical lights-off transition.
The Anden Advantage
Why do professional cultivators choose an Anden dehumidifier over other
Commercial Dehumidifiers? It comes down to installation flexibility and reliability. These units are designed to be hung overhead, freeing up valuable square footage for your canopy.
-
Flexible Installation: Anden units can be ducted, suspended, or floor-mounted, allowing them to fit into complex facility layouts.
-
Remote Sensing: Most models include remote sensors, ensuring the unit responds to the humidity at the canopy level, not just the air at the unit intake.
-
Alternative Options: If you are comparing top-tier brands, consider
Quest Dehumidifiers for similar overhead capabilities, though Anden is often preferred for its specific variable-speed technology.

Frequently Asked Questions
Why should I buy an Anden dehumidifier instead of a residential unit?
Anden dehumidifiers are purpose-built for cultivation. Plants transpire nearly 97% of the water they receive, creating a moisture load that burns out residential motors quickly. Anden units are designed for continuous operation, high efficiency, and have components protected against the corrosive nature of a grow room environment.
How do I determine which size Anden dehumidifier I need?
You need to match the unit's "Pints Per Day" (PPD) removal capacity to the amount of water you feed your plants. As a rule of thumb, if you feed your plants 50 gallons of water per day, you need to remove roughly 50 gallons (400 pints) of moisture from the air daily.
What is VLGR technology in Anden units?
VLGR stands for Variable Low Grain Refrigerant. This technology allows the dehumidifier to modulate its performance based on the actual load. Instead of just turning fully on or off, it can ramp up or down to maintain extremely precise humidity levels, which saves energy and keeps VPD stable.
Can Anden dehumidifiers be controlled remotely?
Yes, most commercial Anden models feature terminals for low-voltage controls (like the A77 remote control) or can be wired into third-party environmental controllers (like TrolMaster or Growtronix) for full facility automation.
Do these units require a dedicated drain?
Yes. Because an Anden dehumidifier pulls massive amounts of water from the air (often 10-100+ gallons a day depending on the model), they must be plumbed to a drain or a reservoir. They do not use small internal buckets like residential units.
Are Anden units easy to install?
Anden designs their units with installation flexibility in mind. Most models can be suspended from the ceiling to save floor space, or placed on the ground. They also offer various ducting kits if you prefer to keep the unit outside the grow room and duct the air in.
