Technical Highlights | 2000 Litre Steel Bunded Generator Feed Tank

Protective Finish

Double coating of Zinfos: Your 2000 litre generator feed tank is painted with 2 coats of our specially formulated anti-rust coating system designed to give maximum protection – Zinfos 340 WS (150μm WFT / 75μm DFT). If you would like to purchase this paint separately, please click here. We recommend painting your steel tank once a year to achieve the maximum lifespan.

Whilst our Zinfos paint is extremely robust, it is recommended that an alternative paint is used if the tank is to be located in a marine environment, please speak to our sales team for more info.

Tank Colour: Our standard paint colour finish for our lube oil tanks is Slate Grey (RAL 7015). A small tin of “touch-up” paint is included with your new tank for applying when scratches might occur during the installation process. If you want a different colour, choose one by referring to the RAL colour chart (this could add the lead time of up to 1 week).
