Open top frac tanks
An open top frac tank is a steel storage tank with an open roof that gives crews direct access to the liquids inside for filling, pumping, sampling, and cleaning. IRONCLAD Powered by Mersino rents open top steel frac tanks in 500 BBL, 430 BBL, and 240 BBL sizes for temporary liquid storage at refineries, drilling sites, construction projects, and environmental remediation work. Operators can check liquid levels from the walkway, and the smooth interior walls rinse clean quickly between jobs.
Open top steel frac tanks for temporary liquid storage
Each tank stores water and other liquids on the job site where they are needed, and several tanks can be manifolded together when a project calls for more storage capacity. Ironclad offers four open top builds, so you can choose a tank based on volume, footprint, and how your crew needs to reach the contents.
Our 500 BBL open top frac tank (21,000 gallon steel tank) is the largest open top unit in the fleet. It measures 51 feet 6 inches long and comes with four 22-inch side-hinged accessways, a full-length catwalk with safety rails, and a sloped bottom that drains out completely.
Our 430 BBL open top tank (18,000 gallon steel tank) holds 18,060 gallons in a 46-foot body. Three 22-inch side-hinged manways give crews entry for cleaning, and the smooth wall interior has no corrugations or internal rods. Heating coils, level gauges, and an internal or external manifold are available as options.
Our 430 BBL Sabre tank (18,000 gallon steel tank) has an integrated full-length side walkway with fixed handrails and a 48-inch wall between the operator and the product. It also has three side-hinged manways and can be fitted with bolt-in weirs.
Our 240 BBL open top mud tank (10,080 gallon steel tank) is built for drilling and boring operations. It stands 5 feet 6 inches tall with 1/4-inch steel plate floors and sidewalls, a V-sloped bottom for drainage, and removable top-mounted support braces.

Our open top steel frac tanks provide:
These tanks suit jobs where crews need to see the contents, reach them often, and clean the tank out fast. Level charts and optional level gauges help operators track volumes, and each spec sheet lists the exact dimensions, ports, and options for its tank.
Key features and specifications:
- Capacity: 21,000 gallon (500 BBL), 18,000 gallon (430 BBL), and 10,080 gallon (240 BBL) steel tanks cover a wide range of project volumes.
- Construction: Shot-blasted steel bodies with smooth interior walls and no internal rods or cross bracing make rinse-downs faster.
- Drainage: Sloped and V-shaped bottoms with floor-level valved ports allow low point drain-out and easier cleaning.
- Access and monitoring: The open top shows liquid levels at a glance, and side-hinged manways give crews a second way into the tank.
- Safety: Full-length catwalks or side walkways, safety yellow rails, non-slip tread, and operation decals on steps, valves, and hatches protect crews on site.
- Mobility: A fixed rear axle, the same setup found on a typical frac tank trailer, and a nose rail cut-out for hose connections make each tank easier to position and hook up.
Open top tanks support liquid storage and waste management at chemical plants, paper mills, petroleum refineries, and across the environmental services sector. They hold water, runoff, non-caustic chemicals, and drilling fluids that are being stored, pumped, or treated.
- Environmental remediation: Contain contaminated water and runoff water during cleanup and stormwater projects until it can be treated or discharged.
- Oil and gas industry: Store and mix drilling mud and other drilling fluid during hydraulic fracturing and drilling operations, or stage water on sites where a frac pond is not practical.
- Fluid storage: Provide static storage for water, diesel fuel, oils, and non-caustic chemicals with open access for sampling and pump transfers.
- Water treatment: Fit the Sabre tank with bolt-in weirs to let solids settle out of liquids before they move on for treatment or disposal.
Why rent an open top frac tank
Renting specialty containment assets from Ironclad gives industrial teams three clear advantages.
Ironclad handles delivery, setup, pickup, and site cleanup for every tank rental. The team is available 24/7 if questions come up while the tank is in service.
Each open top steel tank is hydrotested after every rental to confirm it holds liquid without leaks before it goes out to the next job site.
A frac tank rental lets you add tanks as volumes rise and return them as the work winds down, which keeps equipment costs tied to the project schedule.
A full dewatering setup from one provider
Ironclad maintains the largest specialty containment fleet in the U.S. The dewatering box also comes in 20 and 30 yard sizes, alongside vacuum boxes, metal lid boxes, roll-tarp boxes, and frac tanks for the liquid that drains off. Renting the pumps, hoses, and filtration from the same source keeps the whole dewatering setup on one account.
Share the material type, expected volume, and disposal plan with the Ironclad team, and they will recommend the right dewatering box rental for your site.
