DIABLO line of horizontal tanks is made of recyclable HDPE material, consisting of a full range of 10 models complying with international standards. DIABLO can be used for fuels such as gasoline, diesel, ethanol, alternative fuels and organic vegetable oils. It can be also used for either fresh or waste water. The advantage of this line of tanks is the ‘EASY SWITCH’ plate, which can be purchased separately based on the use of the tank, and it is manually interchangeable. The plate used for fuel comes in red colour, the plate for fresh water in blue colour and the one for waste water in brown colour. It is secured and sealed by rotation of the piece itself and is blocked into position by means of a locking pin that prevents loosening. To clean the tank just lift the locking pin and remove the hatch by unscrewing it.
