Overfill Protection (OP) Tanks:
Highland Tank's OP Tank is designed to eliminate the worry, the mess, and the danger of aboveground storage tank overfills. Highland's OP Tank captures and stores delivery overfills resulting from mistakes or failures during filling operations. Our patented design safely directs the overfilled product via the Overfill Protector into the OP Chamber. The OP Chamber is large enough to contain a spill of at least 20% of the tank's storage volume, so there is plenty of room to contain even high volume overfills. Unlike other forms of secondary containment, the OP keeps the product in the storage tank where it can be easily recovered and reused.
The OP Tank's innovative design eliminates the root causes of spills to the environment and, in many cases, reduces the need for installing a dike around the tank. The entire OP Tank is UL listed for flammable and combustible product storage and is available as a UL-2085 Fireguard® tank or as a standard single or double- walled UL-142 Horizontal Tank.
