Both are vacuum-insulated vessels. A speed tank is configured for high flow — it delivers product faster, which matters when you are filling equipment or vehicles and dwell time is the constraint. A standard dewar prioritises storage duty and hold time.
From compact 80L portable dewars through to 1000L and larger horizontal cylinders, in both vertical and horizontal configurations.
The U-stamp certifies that the vessel was designed, fabricated and inspected under ASME Section VIII Division 1 by an accredited manufacturer. Many industrial and medical gas users specify it, and it is available as an option across our range.
Our cylinders are built for long vacuum-retention life, which is the single biggest factor in whether a dewar stays economic over its service life. A vessel that loses vacuum loses product continuously and has to be re-evacuated or replaced.
Yes. Food-grade LCO₂ is a standard application, alongside industrial and medical gas supply, on-site LNG, and laboratory, welding and electronics gases.
