Mini Frac Tanks are a perfect alternative to a 21K Frac Tank when a job requires less storage or a smaller footprint for the working area at hand. Mini Fracs have many of the same features as a normal frac tank, such as an epoxy liner, which makes them ideal for storage of everything from clean water to fuel to transformer oil and even some chemicals, depending upon capability. These tanks are also equipped with front and rear fill ports for easy and safe tank filling.
