FAQs
Below are some FAQs related to our gas cylinder filling service:
Yes! Many different kinds of gas canisters are designed to be refilled again and again. Refilling is typically the most economical, environmentally friendly, and sustainable solution. It means you don’t have to purchase and then dispose of a new gas canister every time you need gas — a gas bottle refill keeps the canister in circulation.
We can offer gas cylinder filling on our range of CO2, Nitrogen, Oxygen, Argon, Propane, Butane and Helium gases.
We offer a professional service that removes the need for single-disposal or recycling your empty gas canisters. Our service works on a rental system – so the reusable canisters are owned, maintained, and regularly tested by us and then rented to you through a refundable deposit. When your gas bottle is empty, we can refill it for you, or you can choose to return the empty canister, and we’ll simply refund your deposit.
Weighing gas is one of the most accurate ways to see how much is left in the bottle. Another method is to fill a jug with warm (never boiling) water and carefully pour it down the side of your bottle. After about 5-10 seconds, you should be able to feel a temperature change on the side of the cylinder. Where the bottle is cold to touch, this will indicate the level of gas inside the bottle.
To work out how long your bottle will last, you should multiply the cylinder size in kg by 14. The gas application is a significant factor in how long your bottle will last because it determines how much gas you need.
For example, a 45kg cooking gas bottle can last around 244 days, depending on the burner and the frequency you use it. If you have a Calor gas propane 6kg bottle and consider that 1kg of propane can give around 13.6 kWh of energy – you will be able to cook for approximately 81.6 hours.
We accept unwanted gas canisters so we can safely dispose of them or refill them. We’re experts in recycling, repurposing and gas cylinder filling. If you want to learn more about refillable gas, you can trust Adams Gas to give you honest and reliable advice on all gas-related queries.
No. Gas canisters are classed as hazardous waste and need to be disposed of carefully – or better yet, refilled or recycled. Gas canisters are pressurised and could still contain gas even if you think they’re empty. You should never put a gas canister in the bin as improper disposal could lead to an explosion or a fire — especially if the bottle is subject to industrial crushing at a waste processing facility.
