Product Overview

Our closed-top 21,000-gallon (500 BBL) insulated frac tanks retain the temperature of stored liquids even in freezing temperatures. Liquids stored at 104⁰F lose only 9⁰F over a 72-hour period, compared to 59⁰F in non-insulated tanks.

Using expanded polystyrene (EPS) panels, these tanks meet Standard Mechanical Code and International Mechanical Code requirements. EPS panels can withstand temperature cycling, are moisture-resistant and recyclable, and do not harm air or groundwater.
