Harlequin 1225 Litre Slimline Bunded Oil Tank
The Harlequin 1225 Litre Slimline Bunded Oil Tank is designed for the safe storage of heating oil in domestic, commercial and agricultural installations where space is limited. Its slimline footprint makes it ideal for positioning alongside buildings and in narrow access areas. As a result, it is a practical choice where a standard oil tank may not fit.
Manufactured from durable Medium Density Polyethylene (MDPE), this integrally bunded oil tank offers excellent reliability, corrosion resistance and low maintenance. In addition, the robust double-skinned construction provides extra protection against accidental leaks.
A bunded oil tank is often described as a “tank within a tank”. The inner tank stores the fuel. Meanwhile, the outer bund provides secondary containment. This helps prevent ground contamination and supports compliance with current oil storage regulations.
Furthermore, the Harlequin 1225 Litre Slimline Bunded Oil Tank is suitable for domestic heating oil storage, commercial premises and agricultural applications. It combines durability, environmental protection and dependable performance in one space-saving design.
