Proportional Injection

Proportional Injection

Proportional Injection Systems are reliable and low-cost. Dosatron injectors are simple to operate and rely only on your water system’s pressure to provide accurate injection of your pre-mixed fertilizer solutions.

Many growers want to be able to fertilize just a bench or an area or perhaps use a fungicide on only one crop. This can be difficult if your injection system uses a common mainline to supply all areas. Some growers have mounted proportional injectors on hand carts with a pail for supply or used a wagon but if you ever pulled on a hose and watched your cart tip over and your injector crack as it hit the ground, you would know why we developed a Dosatron Cart that will last a lifetime.

Dosatron carts are for fertigation on the go. From single units to comprehensive systems, Dosatron has been the proportional injector of choice for AdeptAg (Zwart Systems) for over 25 years. Discover the difference Dosatron can make in your greenhouse, garden center, or nursery.

Proportional Injection System

Parallel System

Scrolling Dosatron integrates a small PLC and flow meter to allow the Dosatron to activate or deactivate as water volume flow rates change over the irrigation day. As an example, this system can be designed using four (4) 40gpm Dosatrons plumbed in parallel and scrolled to open, adjusting to flowrate evenly from a minimal rate of 10 gpm up to a max flow rate of 160 gpm. This system evens out fertilizer delivery throughout the irrigation period.

Series System

Pre-plumbed units incorporate Dosatrons plumbed in series for A/B applications.

Dosatron Cart Systems

Dosatron cart systems are designed to make proportional fertilizing and fungicide applications portable. Made with a stainless-steel frame and your choice of pneumatic or solid tires and with a low center of gravity, these carts are rugged and reliable. We offer your choice of 14GPM, 20GPM, or 40GPM injectors, with either a single 20Gal tank or 2 x 12Gal tanks for solutions. Each cart comes with a filter to protect your Dosatron, hose connections that are either threaded or quick-coupling, and a 10’ supply hose. A watering wand storage tube is also added for your convenience.

Options

Options on proportional injection systems include an all-in-one combined system designed to include freshwater pumps on one frame; EC/pH monitoring via a BlueLabs monitoring kit can be added for a quick view of water/fertilizer mix, or a sensor loop can be added that is compatible with your environmental control computer to log and alarm through your farm’s environmental control computer.

ECA Machine, ECA Systems

ECA Systems

Electrolysis of potassium chloride results in Electro Chemical Activated (ECA) water. ECA water is produced freshly on-site and is immediately used for safe and effective disinfection and cleaning of irrigation systems.

Without effective cleaning treatment, biofilm will exist throughout the water system—in pipelines, storage tanks, sprinklers, and drip systems. In addition to causing clogging problems in plumbing lines, biofilm is a breeding ground for plant pathogenic bacteria, fungi, and viruses. Via the water supply, these pathogens can attack plants at their roots.

Biofilm in water can be eliminated by ECA injection. ECA water is produced using electricity, softened water, and potassium chloride.

Grower results have shown that roots are healthier, diseases are dramatically reduced, and cut flowers have lasted longer. ECA Systems is the grower’s best solution for a healthy, virus and bacteria-free water system!

Pump Stations and Valve Manifolds

Pump Stations and Valve Manifolds

AdeptAg has designed a complete line of Pump Stations and Valve Manifolds and offers custom-designed valve manifolds to help simplify your greenhouse irrigation process.

Pump Stations

Many greenhouses struggle to maintain consistent water pressure when the demand for water flow changes on the farm. This leads to uneven boom flow rates and inconsistent nozzle output, and it frustrates those who are hand watering.

AdeptAg has designed a complete line of freshwater and recipe pumping stations to help correct this problem.

Valve Manifolds

As production facilities get larger, so does the need for a centralized irrigation system. Efficiency in time savings, space savings, and safety become key factors.

AdeptAg will design and build your custom valve manifold to help the grower treat each zone with a different fertilizer without having a separate fertigation system for all zones.

Cyclone Pump Set

Cyclone Pump Set

Cyclone Pump Set: Proportional injector systems are an effective way to deliver necessary nutrients to your crop through the irrigation system.  Our Cyclone Pump Sets take out human error possibilities in proportional injection.

One way in which proportional systems can fall short is in human error—stock solutions can be made inconsistent from batch to batch. Injectors can fall out of calibration over time and irrigation will continue to run without alarm warnings when the stock solution is weak, strong, or empty. A second way proportional injectors can be thrown out of calibration is a result of wear and tear on the equipment caused by fertilizer viscosity in the stock solution.

Cyclone Pump Sets are computer-controlled units that consistently deliver temperature-compensated EC/pH monitored fertilizers, track progress, graph history, and send alarms when EC/pH set points are not achieved.

AdeptAg can design a unit that fits your greenhouse or farm requirements. We offer soft start motors or variable frequency drive controls, dual system pumps for emergency backup, direct acid injection (no mixing!), and manual or computer-controlled pre-EC blending valves.
