Harlequin Plastic Tanks

Headquartered in Northern Ireland, UK, Harlequin Manufacturing is one of Europe’s leading providers of innovative polyethylene storage tanks and systems.

While the company’s services and operations have expanded over the last 40 years, the underlying principles of their family-owned business have remained constant.

Harlequin has developed a diverse and innovative product range for its clients in the residential, commercial, and agribusiness sectors.

With their state-of-the-art manufacturing facilities, they engineer a wide range of specialist products. 

Their products are designed and manufactured to exceed the most technical, environmental, and regulatory requirements.

Bunded Oil Tanks

Harlequin bunded oil tank range is available from our online store. Tank capacity ranges from 650 - 9250 litres.

Bunded tanks are the go-to for safely storing your fuel. They provide a safety net in the rare event your inner tank (where the fuel is stored) is compromised or the tank is accidentally overfilled. With environmental impact in mind, the bund is designed to contain any excess and leakages from seeping into the ground. 

Harlequin bunded oil tanks are suitable for domestic, commercial and agricultural use. Made from Medium Density Polyethylene, equipped with a robust lid, have confidence in Harlequin to store your fuel safely and without environmental concern.


They are available in 3 different models:

  • HQi - Bunded Oil Tank (with bottom outlet) only

  • ITE - Bunded Oil Tank, including a bottom outlet fitting kit and an electronic gauge.

  • ITT - Bunded Oil Tank, including a top outlet fitting kit and an electronic gauge. (Only available upon request- call our office for more information)

whether you run a small fleet of vehicles or want to fill your farm vehicles, Harlequin offers 2 solutions to fulfil your feeling needs. Don't need something fancy or the added tech? No problem, Harlequin has a basic solution for you.
