AEtrium Automated Dosing Unit - Precision Hydroponic Dosing, Measurement, Sensing, & Irrigation System

Two Fail Over Pumps, 8 Total Fertigation Channels For All Indoor & Greenhouse Hydroponic Requirements


The fully automated AEtrium Dosing Unit (ADU) is a fully integrated nutrient measurement, dispensing, pH monitoring and nutrient adjustment system for either indoor or greenhouse applications.  It doses volumetrically or via integrated sensor feedback from the dosing reservoir. The AEssenseGrows Guardian Grow Manager software (GGM) provides fingertip control through an easy-to-use variable adjustment interface wirelessly accessible from any desktop, tablet, or mobile phone access point. 

The Automated Dosing Unit can automatically dose from any of 11 available liquid nutrient sources.  Typically 2 of these are reserved for pH management (up/down) but the assignment is fully optional for all 11 fertilizer inputs.  This fertilizer and irrigation system is optionally referred to as a "fertigation" system.

Each of the standard irrigation pumps offer a maximum flow rate of 15.8 gallons/minute (60 lpm) x2 from the integrated reservoir. Temperature, pH, and Electrical Conductivity (EC) are measured constantly and reported to the ADU on board computer for analysis by the GGM.  This makes the AEtrium ADU ideal for any sprinkler, dripper, poly pipe, or flood and drain hydroponic system for greenhouse or indoor applications.

In addition to fertigation, the GGM software can be extended with the use of smart relays to control the complete grow environment from nutrients to air, CO2 management, humidity, temperature, fans, vents, lighting control and timing, and input water and treatment recovery systems.

Full automation is achieved through water level sensors integrated to manage tank fill level, auto fill, auto flush, water temperature, and pH. There is also an optional reservoir cooling coil that can be integrated to chill the reservoir for warmer grow environments. The dual fail-over pumps each have integrated sediment filters that are easily serviced so maintenance requires minimal labor and time.
The system is delivered fully assembled on a shrink wrapped shipping pallet designed for easy forklift movement. Rotational or uni-directional wheels can be mounted to the bottom structure frames for easy manual movement.
The AEtrium ADU system dimensions are 42"x 62"x 82" (L x W x H) and it weighs 573 LBs without water. The standard configuration includes an 80 gallon (302 Liter) reservoir.
