BTU® – Biofuel Tank Upgrade

The BTU®, Biofuel Tank Upgrade, is a cost-effective solution for upgrading existing fiberglass single-wall and double-wall tanks to meet new regulations. Many of the earliest generation fiberglass tanks were not tested nor were they warranted for either biodiesel or ethanol blends exceeding 10%. Upgrade your tank to full compatibility with green fuel blends like E15, E85 up to E100.

The BTU can be applied in combination with typical tank upgrades like sumps and collars or as a stand-alone service. Unlike conventional tank lining methods, the BTU upgrade is completed by CSI technicians who are experts in fiberglass tank manufacturing techniques.

In most cases the candidates for the BTU are older tanks. All Containment Solutions single-wall and double-wall storage tanks are compatible with ethanol blends up to E100 and biodiesel blends up to B100.
