ADVANTAGES OF ‘TWIN SKIN’ TANKS

With growing demand for environmental protection, advantages of Hartwell ‘Twin Skin’ double integrity fuel oil and chemical storage tanks are increasingly recognised. Open spillage bunds present hazards and drainage problems, eliminated entirely by containing spilled fuels and noxious liquids inside their own integral bund compartments. Significant open bund space and civil cost savings can be achieved.

STANDARD RANGE TANKS

EXTERNALLY STIFFENED & SPECIAL TANKS

If rectangular tanks cannot be manufactured with internal cross stays, external channels or angles are welded to achieve the same performance. Non standard tanks are specially designed by Hartwell, with prices on application.

SITE WELDED TANKS

When access to site is difficult, i.e. basements, rooftops, tanks are prepared in small sections before being welded, tested and painted in situ. Supply and erection costs, will be confirmed by Hartwell following site visit although it is often possible to give close budget prices without site inspection.
