Dosatron® D25F Fixed Ratio Medicator Injector

Product Overview

Chemical injection failure during the height of the growing season leads to immediate nutrient deficiencies, crop loss, and costly emergency repairs. When your fertigation system goes down, your crews face the pressure of manual feeding or watching high-value plant material deteriorate rapidly. With global supply chains remaining unpredictable, waiting until an old injector fails means risking long lead times and project delays that damage your reputation. Securing a reliable Dosatron unit now ensures your systems remain operational when the summer heat puts the most stress on your clients' landscapes and crops.

The Dosatron D25F Fixed Ratio Medicator stands apart from electric injectors by operating entirely on water pressure. This eliminates the need for electrical proximity and protects your installs from power surges or outages that can disable automated systems. By utilizing a fixed dose rate, you remove the risk of operator error or accidental adjustment, ensuring consistent chemical delivery every time the water flows. This simplified design reduces labor costs associated with calibration and long-term maintenance, providing you with a predictable, high-performance solution that outlasts lower-grade suction venturis.

Installation Notes

Install the Dosatron D25F on the main water line with a 200 mesh filter placed upstream to prevent debris from damaging the internal piston. Use a bypass assembly with three ball valves to allow for easy servicing or winterization without interrupting the primary water supply. Ensure the unit is mounted vertically with the suction hose submerged in a clean stock tank, and always follow local backflow prevention codes to protect the potable water source.
