Advanced M-CORR Technology for Commercial Grow Rooms
The Anden A711 features M-CORR (Multi-Coil Refrigerant Recovery) technology, which improves moisture removal efficiency across varying operating conditions.
Its multi-coil configuration optimizes refrigerant recovery, helping the dehumidifier operate across a wider dewpoint range while reducing unnecessary defrost cycles.
This technology is particularly valuable during flowering, when indoor cultivation facilities experience significant moisture loads.
By maintaining more consistent humidity, the A711 helps growers manage VPD throughout different growth stages.
High-Capacity Moisture Removal
Rated at 705 pints per day at 80°F (26.7°C) and 60% relative humidity, the A711 is designed for large spaces requiring substantial dehumidification.
Its 1,800 CFM airflow circulates humid air through the refrigeration system, where moisture condenses and drains away.
The unit then returns dehumidified air to the growing environment.
Flexible Installation Options
The Anden A711 accommodates three installation configurations:
-
Suspended: Integrated mounting points allow overhead installation to preserve cultivation space.
-
Freestanding: Adjustable leveling feet support floor installation.
-
Ducted: Optional inlet and exhaust adapters allow installation in an adjacent equipment room.
Digital Humidity Control
The A711 includes an onboard digital interface for adjusting humidity settings and accessing diagnostic information.
A low-voltage terminal block supports compatible external humidity controllers, allowing remote control from an appropriate location.
