What is a Bunded Diesel Tank?

A Bunded Diesel Tank consists of a tank within a tank. Diesel is stored inside the inner tank, whilst the outer tank can hold at least 110% of the volume of the inner tank and acts as a failsafe in the event of a spill. Should a spill occur, spilt fuel will be contained inside the outer tank and a potential environmental pollution incident will be avoided.

Do you supply Gravity Fed Diesel Dispensing Kits?

As an environmentally responsible fuel tank supplier, we do not supply gravity fed delivery kits. This is due to the significant risk of an environmental pollution associated with such systems. Furthermore, at many Diesel storage installations today, the use of such systems is effectively prohibited by law.

No. HVO is produced through the hydrogenation or hydrocracking of waste vegetable oils, whereas Biodiesel is produced using transesterfication.

Many Diesel Tanks are now either HVO compatible, or can be ordered with a HVO upgrade kit, allowing them to be used with HVO fuel. 

Can I store HVO in an existing Diesel Tank? 

Research has shown that whilst in many instances, existing Diesel Tanks may be compatible with HVO, the wetted components fitted to them may not be. It's therefore recommended that you contact your storage tank supplier to confirm compatibility, before taking delivery of HVO.
