What Is a Dry Add Unit?
A dry add unit — also called a dry polymer frac unit — is a piece of wellsite equipment that feeds dry polyacrylamide (friction reducer) directly into your frac water stream as it flows. Instead of pre-mixing liquid emulsion friction reducers, the system meters dry polymer powder on the fly and hydrates it inline before it reaches the blender.
This approach gives you tighter control over your polymer dosage, reduces liquid chemical handling on location, and cuts down the logistics headaches that come with transporting and storing large volumes of liquid friction reducer.
The short answer: A dry add unit replaces your liquid FR totes with a bulk polymer tote, a precision metering system, and a computer that handles the rest.
Why Operators in Norman and the Anadarko Basin Use Dry Polymer Systems
Why Operators in Norman and the Anadarko Basin Use Dry Polymer Systems
Oklahoma’s Anadarko Basin is one of the most active natural gas and oil-producing regions in the country. Whether you’re completing horizontal wells in the SCOOP, STACK, or other Anadarko plays, your friction reducer performance directly affects pump pressure, proppant transport, and ultimately your well production.
Here’s why operators in this region are moving toward dry polymer delivery:
Lower chemical cost per stage. Dry polyacrylamide costs less per pound than equivalent liquid emulsion friction reducers. Field studies have shown operators achieving 30% to 37% cost reductions per stage after switching from liquid FR to dry powder delivery.
No freezing issues in Oklahoma winters. Liquid friction reducers can separate or freeze during cold weather, causing inconsistent dosing. Dry polymer doesn’t have that problem.
Better water quality matching. The Anadarko Basin produces a mix of freshwater and high-TDS produced water. Dry FR systems with real-time water analytics let you adjust polymer performance on the fly as your water quality changes — something liquid systems can’t do efficiently.
Smaller location footprint. A single 2,500 lb. poly tote replaces multiple liquid FR totes. Less equipment on location means a cleaner pad and easier logistics.
Reduced HSE exposure. Dry systems eliminate the risk of liquid FR spills on location. No slippery surfaces, no large volumes of emulsion chemicals to manage.

REALTIME WATER AND POLYMER ANALYTICS
This is where our dry add units stand out from basic dry polymer systems.
Most equipment just meters the dry polymer and sends it downstream. Our units run a water slip stream alongside the polymer feeder. That slip stream continuously measures your frac water quality using electronic probes, and records everything throughout the job.
This matters because frac water quality in the Anadarko Basin changes. Produced water ratios shift, TDS levels vary between stages, and pH swings can affect your polymer hydration and friction reduction performance. If you don’t know what your water is doing, you can’t know what your polymer is doing.
What we monitor in real time:
- Dissolved Oxygen (DO)
- Water Temperature
- pH
- ORP (Oxidative Reduction Potential)
- FAC (Free Available Chlorine)
- Conductivity
- Resistivity
- Polymer Viscosity and Pressure Profile
All of these measurements are made continuously throughout the entire frac water volume. The data is recorded against polymer performance, so you can build cause-and-effect relationships between water quality changes and polymer behavior. That’s the foundation for making smarter polymer adjustments on the fly — not just reacting to problems after the fact.
Cloud-Based Data Logging
Every job run through our dry add units is fully logged and accessible through our cloud-based system.
That means your operations team, your completion engineers, and your lab personnel can all see the same data in real time — from the wellsite or from the office. After the job, you have a complete record of:
Polymer dosage rates per stage
Viscosity readings throughout the job
Water quality measurements for every stage
Pressure profile data
This kind of job-level documentation is increasingly important for completion optimization. You can compare performance across wells, identify trends in water quality changes, and use that data to sharpen your friction reducer selection and dosage on future jobs.

What is a dry add unit used for in hydraulic fracturing?
A dry add unit feeds dry polyacrylamide friction reducer into your frac water stream in real time. It meters the dry polymer powder at a precise dosage rate, hydrates it inline, and delivers it to your blender — replacing the liquid emulsion friction reducer traditionally pumped from totes.
Where is 4S Chemicals located?
We’re based at 3800 Classen Blvd., Norman, OK 73071. We serve operators and oilfield service companies throughout the Anadarko Basin and central Oklahoma region.
What dosage range does the 4S Chemicals dry add unit handle?
Our units operate from 0.25 to 4.0 GPT. That range covers standard slickwater frac operations as well as higher-viscosity applications where more polymer is needed for proppant transport.
Can your dry add unit handle produced water?
Yes. Our real-time water analytics system monitors conductivity, resistivity, TDS, and other water quality parameters continuously throughout the job. This allows polymer adjustments to be made on the fly as produced water ratios shift during a stage.
What type of polymer works with your dry add unit?
Our units are designed for dry polyacrylamide (PAM) friction reducers in bulk poly tote format. Contact us to discuss compatibility with specific polymer grades or products you’re using in the field.
How much polymer does the storage tote hold?
The bulk storage tote holds up to 2,500 lbs. of dry polymer. The 45-degree sloped bottom and slide gate ensure clean, consistent flow without bridging.
Is the unit dust-free?
Yes. Our dry add units are designed for dust-free operation, reducing worker exposure to dry polymer dust on location.
Do you offer lab services alongside equipment?
Yes. 4S Chemicals also offers lab services to support your completed chemistry decisions. Visit our Lab Services page for more information.
