PROTECline

When an IBC container or tank is black, this is not merely an aesthetic choice. The colour serves a specific purpose, primarily offering protection against UV radiation. At WERIT, we refer to such products as PROTECline and use special colourants, known as additives. When handling light-sensitive filling materials, these containers are often referred to as a "1,000 litre black water tank" or the smaller version, the "600 litre black IBC container". The principle is comparable to that of a brown or dark green beverage bottle, though black provides even more comprehensive UV protection. Although HDPE is inherently a robust material, it can suffer under intense UV exposure and lose elasticity.
We always recommend storing the containers in a shaded area whenever possible. A white variant is also available on request.

IBC containers offer a certain degree of UV resistance. While this cannot be precisely quantified in advance, HDPE is known for its remarkable durability and strength. The "HD" stands for "high density", while "PE" refers to polyethylene as the base material. Available volumes include 300, 600, 800, and 1,000 litres, with standard models suitable for substances with a density of up to 1.6 g/cm³. Their dimensions correspond to pallet sizes: the 600-litre model fits a Euro pallet (1,200 x 800 mm), the 300-litre version measures half that (600 x 800 mm), and the 1,000-litre model is compatible with an industrial pallet (1,000 x 1,200 mm).

The UV protection provided by black IBC containers often raises the question of their suitability for storing petrol or diesel. It is essential to observe UN hazardous materials classifications and ensure the container meets specific resistance requirements. This is due to the volatile nature of petrol and potential expansion of the container. Proper grounding is also necessary due to explosion risks. Diesel is commonly stored in IBC containers in agricultural settings, though special approval is required. A practical benefit is that, with volumes up to 1,000 litres, above-ground storage is permitted without a separate containment unit, allowing storage directly on pallets.
