ST. MARYS, Ont. – Robica Forman Tank has developed a clever solution for a customer that will save them about $300,000 per year.

Hydro One has taken delivery of the first of six Mammoth TOT (Transformer Oil Treatment) trailers. The trailer, custom-built by Robica, can replace anywhere from three to six conventional trailers at a job site.

Traditionally, Hydro One required two to three tankers at a site to hold oil and an additional one or two trailers to house the filtration and heating systems, according to Bob Nothof, vice-president and general manager of Robica.

The new design can accommodate 90,000 litres of transformer oil as well as all the heating and filtering components. Its square design also adds capacity, providing a quick payback for the provincial utility.

Robica engineers have been working on the design of the new trailer for more than a year. Despite the sluggish economy and its impact on the trucking industry, Robica Forman Tank is in the process of adding capacity at its plant and is planning on hiring more workers.
