Dosatron Athena Pro Kit – Professional Dosing Kit with D3RE2 and D3RE3000 VF/AF

The Dosatron Athena Pro Kit is a professional fertigation system built around the D3RE range: four proportional injectors combined with the mixing chambers and inline accessories required to precisely and consistently inject a multi-part recipe, without electricity.

What is a Dosatron proportional dosing pump?

Dosatron is a French manufacturer based in Tresses that has been making hydraulic proportional dosing pumps since 1974. The injector is installed inline with the irrigation water and uses the pressure of the water itself as its sole driving force: it has no motor or electrical connection.

It draws the concentrate from the container and injects it at a fixed percentage of the flow, so the dosage is always proportional to the volume of water, even if the flow and pressure vary. That is the real difference compared to a peristaltic pump, which delivers a volume over time and throws off the recipe as soon as the system flow changes.

What is included in the Athena Pro Kit?

• 3 mixing chambers (HYKMC34-BSP), to homogenize the solution inline between injections.
• Starter kit (HYKSTART-STD-BSP): isolation ball valve, 200 mesh filter (80 µm), inlet pressure gauge, fresh water port, check valve, and BSP accessories.
• Monitor kit (HYKNOMON-BSP): to read the EC and pH of the outlet solution, with an integrated mixing chamber. Monitor not included.
• Surge tank: absorbs the water hammer when the solenoid valves open and close.
• 1 x D3RE3000 VF (0.03 - 0.3 %).
• 2 x D3RE2 (0.2 - 2 %).
• 1 x D3RE3000 AF (0.03 - 0.3%, Aflas seals).

Why this kit includes an AF injector

It is not a minor detail or an aesthetic variation: VF and AF are not interchangeable.

• VF uses Viton seals and is designed for neutral or acidic products: base fertilizer, pH down regulators, and most additives.
• AF uses AFLAS seals and is the one that must be used with alkaline, high-pH products: pH Up, silicates, and similar products. Viton degrades when exposed to them; Aflas withstands them.

That is why the kit includes three VF units and one AF: the alkaline line of the recipe has its own pump with the correct chemistry. Mounting an alkaline product in a VF head drastically shortens the life of the seals.

Injector specifications

• D3RE2: flow rate of 10 l/h to 3 m³/h, pressure 0.3 - 6 bar, dosing 0.2 - 2% (2 - 20 ml/l), 3/4" connection, integrated bypass.
• D3RE3000 VF / AF: same flow rate and pressure, dosing 0.03 - 0.3% (0.3 - 3 ml/l), polypropylene body, 3/4" NPT connection, maximum temperature 40 °C.

How to choose your Dosatron equipment

1. System flow rate: up to about 1,100 l/h, Hobby range. Up to 3,000 l/h, D3RE / D14MZ range.
2. Available pressure: the Hobby range requires a minimum of 2.5 bar. This is the most common mistake: it will not work with 1.5 bar of network pressure. The D3RE, on the other hand, starts at 0.3 bar.
3. Recipe percentage: for concentrated base fertilizer, 0.2 - 2% (D3RE2). For additive, pH, or silicate, 0.03 - 0.3% (D3RE3000).
4. Product chemistry: VF (Viton) for neutral or acidic products; AF (Aflas) for alkaline products.
5. One pump per container: a 4-part recipe requires 4 pumps in series. That is why this equipment is sold in kits.

Every item goes through a check before shipping to make sure it arrives in perfect condition and ready to use.

Your satisfaction is our priority.

1. Assign each container in your recipe to a doser: the D3RE2s for concentrated bases and the D3RE3000s for additives, pH, or silicate.
2. Place the alkaline product in the D3RE3000 AF (Aflas seals). Never mount it on a VF head: the Viton seals will degrade.
3. Install the starter kit at the beginning of the line: ball valve, 200 mesh filter, pressure gauge, fresh water port, and check valve.
4. Mount the four dosers in series, alternating the mixing chambers and respecting the flow direction of each body.
5. Place the shock absorber to absorb the water hammer from the solenoid valves and the monitor kit at the end to measure the output EC and pH.
6. Adjust the percentage of each pump, open the water slowly, purge the air, and check the output reading before watering the crop.
