Can your tank be used in below freezing temperatures?

Our tanks are made from polyethylene formulated for low temperature impact resistance. The resin is designed for use down to -20 degrees F per ASTM D 1998 (the specification used for tanks like ours) and ARM (The Association of Rotational Molders). Keep in mind that liquids expand when frozen due to entrapped air, so allow extra space in your tank to accommodate this in low temperature applications. The most likely part to crack on the tank is the bulkhead fitting which can be easily replaced.
