SPEL Tankstor® Above Ground Tanks

SPEL Tankstor® Above Ground tank systems are available in both horizontal and vertical format and are suitable for a number of applications including temporary fluid storage. These tanks are designed and built to a dedicated specification for above ground applications, referenced to the British Standard BS EN 13121, and also benefit from the SPEL 25 Year Warranty. SPEL Tankstor® H Series Horizontal Tanks are available in the full range of sizes and rely on a simple cradle system for structural and location stability. The V Series Vertical Tanks are available in three diameters; 1.8, 2.6 & 4m and are delivered with flat bases and galvanised steel hold-down brackets for stability. All SPEL Above Ground Tank Systems can be supplied with galvanised steel access ladders and platforms to ensure safe access and maintenance. Secondary Containment by means of a second GRP skin is available to eliminate storage bunds subject to design criteria.  

SPEL manufacture both Horizontal and Vertical Above Ground Tanks for many applications. Check out the Horizontal and Vertical Above Ground Tank tabs above for more information.

SPEL are increasingly supplying above ground tanks where below ground installation is costly and/or complex or surface area is not at a premium. This is particularly applicable where the ground is contaminated or unstable, or where the application is temporary.

Horizontal SPEL Tankstor® tanks are mounted on adjustable galvanised steel cradles fixed to a suitable preformed concrete slab designed for the required loadings. In addition to the cradles manway access and maintenance platforms are bespoke designed to meet site requirements.

Secondary bunding is required on many fluid storage applications and the SPEL Double Skin system provides this as an integral part of the tank when required. This can be further enhanced by the SPEL cavity monitoring system which detects pressure and/or fluid changes activating an alarm when this is detected.

All SPEL Above Ground tanks have the additional option of the 3 internal laminate specifications; General Purpose (GP), Chemical Resistant (CR), and Highly Chemical Resistant (HCR), these allow for storage of a range of aggressive chemicals/fluids at a range of temperatures. For more information on laminate specifications, see Page 3.13.

SPEL Tankstor® vertical above ground tanks provide efficient fluid storage where limited space is available. The system requires a suitable concrete base slab (designed to support the maximum load), the tank(s) are then positioned and bolted to the base slab via the galvanised steel anchor points, this gives excellent stability.

As with the horizontal system, the V Series tanks can have access platforms, ladders and low level service hatches to make for safe and efficient maintenance.
