The Ideal Size For Any Installation.

The Roth DWT tank line is comprised of an all-virgin blow molded “bottle” encased in roll-seam galvanized exterior tank that provides the secondary containment. Each tank is provided with four – 2” female NPT fittings to accommodate piping, pumps, etc.

After the manufacturing process each polyethylene bottle is tested to 4.35 psig for leaks and the exterior tank is tested to 0.5 psig ensuring that both are completely sealed and suitable for use. The interstitial space between the tanks is also outfitted with a leak detector and a visual alarm should oil be released into the space. Each model also comes with a cradle as standard equipment that keeps the tank off the floor.
