Rent Free Co2 Cylinders for Yorkshire

Aquarium Co2 Cylinders

All Co2 Bottles/Cylinders we Supply are Rent Free

Carbon Dioxide (Co2) is held in its liquid form by the pressure of the gas.

When the gas is drawn off the liquid evaporates until an equilibrium is created at approximately 57 bar (830psi). It is for this reason your Co2 regulator will not show the amount of gas left in the cylinder as the regulator will only show the pressure not the amount of liquid Co2 remaining in the cylinder.

Our cylinder only contain 'food grade' Co2 known in the trade as 'Beer Gas' or 'Cellar gas' as supplied to restaurants, pubs, clubs etc. and do not contain low grade Co2 used in Carbon Dioxide Fire Extinguishers, why risk damaging you healthy plants & fish with cheap low grade Co2

Here at Doncaster we invested in a special liquid Co2 pump so we could pump the liquid Co2 from our 45kg cylinders into the smaller receiving cylinder this allows us to put the full amount (3.00kg 6.00kg 15.00kg or 22.50kg) by weight into the cylinder.

Co2 cylinders contain liquid Co2 and are sold by weight, the sizes we stock are:- 

Small about 520mm high 3kg of Co2, 

Pub size about 830mm high 6.35 kg of Co2 

Short about 650mm high 6kg of Co2.

Large 1200mm X 175mm 22.5kg of Co2

All cylinders must have a safety certificate which will be held by the person or company who had the cylinder tested, the plastic disc between the valve and cylinder body states the 'Retest (year) the month is usually numbers round the edge 1 to 12 with a mark or stamp on the relevant month. The test could be 5 or 10 years, no cylinder can be filled with out a current test

Out of date cylinders can be part exchanged against a new cylinder but cannot be filled
