New Product: 2500 Underground Oil Tank

New Product: 2500 Underground Oil Tank
02 May 2018

Harlequin Manufacturing Ltd. are proud to announce the launch of their 2500 Double Walled Underground Oil Tank to their Underground Oil Tanks Range giving home owners more options to choose from when buying an underground oil tank. 
Much like the earlier 1400 Litre version, this tank has a double walled design with an interstitial leak detection monitor.  If there is a leakage, this monitor detects it and alerts the owner, thus containing the leakage within its second wall preventing it from harming the surrounding environment.
The tank fully complies with best practice guidelines outlined in PPG27 and BS5410 and includes the following features: 2” fill point, Offtake (anti siphon valve & filter), contents gauge, overfill prevention valve, tiger loop and the interstitial leak detection monitor.
Single-skinned and double-walled tanks also come with a new and improved lockable hinged access lid with brick effect surround. The new lid has been designed to be more aesthetic and blends in well with any type of landscaping. This new modern lid style has been designed to prevent water ingress and provides convenient access for tank filling and maintenance.
Underground Oil Tanks provide secure storage for heating oil, increasing useable garden space and are a popular choice for small gardens and sensitive landscapes.
