Inside MIDSPEC

A cost-effective alternative to premium Intanka® installations to underground fuel storage and handling equipment on service stations across Australia.
TRL Engineering is proud to announce it's new MIDSPEC Tank Lining product, a specialised solution designed for Australian petroleum retailers seeking a cheaper, lower-spec option for upgrading and protecting their underground petroleum storage tanks.
For years, the installation of the Intanka® system on service stations, has set the benchmark in the industry, delivering the highest level of durability, chemical resistance, and long-term structural integrity.
However, not all operators require or can justify the investment in a premium, top-end system.
Recognising this need, TRL Engineering have developed MIDSPEC, a practical, affordable alternative.
Future-proof your assets
MID-SPEC’s fiberglass system seals and futureproofs existing tanks with minimal operational disturbance.
MID-SPEC allows for an automated leak detection system, giving piece of mind to investments.
Maximise storage configuration with bulkheads where two different fuels - such as Diesel and E10 - can be stored within the same tank.
