What Is A Dosatron?

Quick Answer: A Dosatron is a water-powered dosing system that automatically injects a concentrated product into a flowing water supply at a predetermined ratio. Dosatrons are widely used in agriculture, industry and professional exterior cleaning, including softwashing, roof cleaning, render cleaning and biocide application.

What Does A Dosatron Do?

A Dosatron automatically mixes a concentrated product with water as the water flows through the unit.

This removes the need to manually measure and mix large quantities of solution before application.

In professional softwashing, this can help contractors apply cleaning solutions and treatment products more consistently across larger projects.

How Does A Dosatron Work?

Unlike electric pumps, a Dosatron is powered by water flow.

As water passes through the unit, an internal mechanism draws concentrate from a separate container and injects it into the water stream at a controlled ratio.

Why Are Dosatrons Popular In Softwashing?

Softwashing contractors often need to prepare large volumes of working solution.

A Dosatron can simplify this process by automatically dosing concentrate into the water supply during application.

This can help improve efficiency, consistency and productivity on larger projects.

What Are The Advantages Of A Dosatron?

Automatic dilution
Consistent mixing ratios
Reduced manual measuring
Efficient application
Portable operation
Scalable for larger projects
Useful for professional softwashing systems
Reduced batch mixing time
Improved repeatability across jobs

Do Dosatrons Require Electricity?

No.

Most Dosatron systems operate purely from water flow and do not require electrical power to perform the dosing function.

This makes them useful for contractors working on sites where a simple water-powered dosing method is preferred.

Can Dosatrons Be Used With Different Products?

Different Dosatron models are designed for different applications, flow rates and dosing ranges.

Contractors should always check manufacturer guidance, chemical compatibility and product instructions before use.

Commonly used products include:

Why Do Contractors Like Consistent Dilution Ratios?

Consistency helps improve repeatability across projects.

Many contractors prefer systems that help maintain accurate and repeatable mixing procedures.

This can be particularly useful when working across roof cleaning, render cleaning and maintenance treatment projects.

Consistent dilution also helps with pricing, product usage, customer expectations and professional workflow.

What Is The Difference Between A Dosatron And A Pump Sprayer?

A pump sprayer stores a pre-mixed solution inside a tank.

A Dosatron creates the working solution as water flows through the unit.

Both systems have advantages depending on the project requirements, budget and workload.

What Size Dosatron Do I Need?

Different Dosatron models are designed to operate across different flow rates and dosing ranges.

The correct model depends on factors such as water supply, application volume, chemical type and workload.

Which Dosatron Should I Buy?

The most suitable Dosatron depends on your application requirements, water flow, product compatibility and business goals.

New contractors should avoid buying equipment based on price alone and should consider what they intend to clean, how often they will use the system and what support they need.
