The Dosatron D14WL is a low-flow chlorinator purpose-built for drinking water disinfection. Powered entirely by water pressure, it delivers proportional, accurate chlorine dosing without electricity, complex controls, or external power supply — making it one of the most reliable and cost-effective chlorination solutions for small-scale water treatment.
Whether you're treating a private well, supplying a rural community, or managing a small municipal system, the D14WL ensures that every gallon of water receives the exact same chlorine concentration — automatically adjusting to changes in flow rate and pressure.
The D14WL runs on water pressure alone — no electricity, no batteries, no motor. This eliminates the risk of power outages disrupting your water treatment and removes electrical hazards from the installation. It's the ideal solution for off-grid locations, remote communities, and areas with unreliable power.
The dosing ratio is set once and maintained automatically. Whether your flow is at 0.05 GPM or 14 GPM, the chlorine-to-water ratio stays the same. No manual adjustment needed. No over- or under-dosing.
The D14WL installs directly on a ¾" NPT water line in a bypass configuration. Included accessories — suction tube, weighted strainer, and mounting bracket — make setup straightforward. Maintenance is simple: periodic inspection, seal replacement (annual injection seal kit available), and wiping down internal components.
The unit draws chlorine solution from a tank up to 4 meters below, with no external suction pump required.
