Smart Drain Control
Precision Irrigation Through Data

Real-time drain data for smarter irrigation decisions
INTA’s Smart Drain Control Tray is the result of years of research and development, designed to provide precise monitoring of drainage volume in hydroponic systems. By entering irrigation reference values, the system automatically adjusts irrigation cycles to maintain the optimal water balance for your crops.
When combined with the TDR substrate sensor, the Smart Drain Control Tray becomes a powerful, integrated solution for monitoring and controlling irrigation in hydroponic cultivation. Up to eight trays can be connected to a single fertigation unit, offering growers accurate data and complete automation across multiple growing zones.


Highlighted functions
A compact, durable tray engineered specifically for high-performance greenhouse environments, ensuring seamless integration into daily operations.
High-precision monitoring for optimal irrigation
Accurately measures drainage volume and interprets crop responses in real time, helping growers maintain the perfect balance between water, oxygen, and nutrients.
Designed for hydroponic crops
Tailored to hydroponic production, making it ideal for demanding crops where precision irrigation directly impacts yield and quality.
Works together with substrate sensors
Combines perfectly with our TDR substrate probes to provide a complete picture of root-zone dynamics. Moisture, conductivity, temperature, and drainage all under control.
Simple installation & flexible setup
Quick to deploy in any greenhouse layout. Up to 8 trays can be connected to a single fertigation system, adapting effortlessly to various crop densities and expansions.
When paired with EVO, irrigation is automatically adjusted to real plant needs, no assumptions, only data-driven control.

CDN: Fertigation
Hydraulic design confirmed over 25 years of experience

Fertilizer mixing tank
Specially designed to produce a homogeneous and quick mixing of the different fertilizers.
Magnetic Pumps
They drive the fertilizer solution from each fertilizer tank to the mixing tank.
3-way dosage electrovalves
They regulate the dosage of the different fertilizers in terms of the proportions established for each tank. As it is 3-way, it permits a return circuit to be maintained with the fertilizer tanks, considerably improving the functioning and precision of the dosage.
Fertilizer flowmeters
High frequency flowmeters which consequently measure the fertilizer dosage volume of each tank with greater precision. They register the consumption in real time, and allow us to automatically adjust the dosage.
pH probe
Robust and reliable pH probe, working in line and with pressure. Essential for a correct pH control via the acid dosage.
EC probe
Measures conductivity, with automatic temperature compensation. Robust and reliable, heavy duty.
Main pump
Multi-stage vertical pump which drives the fertilizer solution. Made in AISI 316 steel. Adjusts model adjusted according to flows and irrigation pressure.
Fertigation Controller
Controls all the described elements, as well as other elements of the irrigation installation.
