Insist on a worry-free Quality of Life and Respect for the Environment
Because you have every reason to expect more, ROTH is an innovator who always goes above and beyond.

More for the environment:
Avoid oil spills and leaks caused by faulty pipes, couplings, or fittings, which are located underneath the tank.*

ROTH double wall tanks are designed to offer the highest level of environmental protection. The inner portion of every ROTH tank is made of blow-molded, seamless high density polyethylene, and absolutely leak-proof and corrosion resistant. In addition, ROTH tanks feature top connections to insure the oil stays where it should.

The outer tank is made of galvanized steel that is also leak-proof and corrosion-resistant, and can contain 110% of the capacity of the inner tank for maximum protection.
