Out of CO₂? Don't Let a Warm Cylinder Make Your Refill Take Longer

There's nothing quite frustrating about running out of CO₂ when you need it.

Whether you use CO₂ for a kegerator, soda, aquarium, home brewing or a beverage system, running out means making a trip for a refill.

And if you're already waiting to get your CO₂ back, the last thing you want is to make that refill take longer than necessary.

One simple thing to keep in mind, especially during Ottawa's warmer months, is the temperature of your cylinder.

Why Does a Warm CO₂ Cylinder Matter?

CO₂ is stored inside a cylinder under pressure. As the cylinder gets warmer, the pressure inside increases.

Temperature can affect the filling process, and a cylinder that has been sitting in significant heat may take longer to refill.

In simple terms:

A warm CO₂ cylinder can mean a longer refill.

That doesn't necessarily mean there's anything wrong with the cylinder. It's simply one of the conditions that can affect the refill process.

Rapid CO₂ normally completes standard CGA-320 CO₂ cylinder refills in under 10 minutes, although actual refill times can vary.

Your Hot Car Could Be the Problem

One of the easiest ways to heat up a CO₂ cylinder is to leave it in a parked vehicle.

During the summer, a vehicle can become very hot. If your cylinder sits in the car while you run errands, shop or have lunch, it can absorb a considerable amount of heat.

So if you're already out of CO₂, the last thing you need is to arrive with a cylinder that has been sitting in a hot vehicle for several hours.

You may end up waiting longer for the refill when you're already waiting to get your CO₂ back.

How Can You Avoid the Extra Wait?

A few simple steps can help:

• Don't leave your cylinder in a hot vehicle for an extended period.

• Keep it out of direct sunlight.

• Avoid leaving it in your vehicle while running errands for hours.

• Let the refill facility know if the cylinder is particularly warm.
  If you're driving directly from home to get your refill, there's no need to overthink it. The main goal is simply to avoid unnecessary heat exposure.

Don't Try to Rapidly Cool a Warm Cylinder

If your cylinder has become warm, don't try to quickly cool it by putting it in a freezer or exposing it to extreme temperature changes.

CO₂ cylinders are pressurised equipment and should be handled appropriately.

The best approach is to avoid unnecessary heat exposure and let the refill process be handled properly.

Check Your Cylinder Before You Come In

Temperature isn't the only thing worth checking.

Your cylinder also needs to be within its applicable requalification period and suitable for filling.

If you're unsure about the testing requirements for your cylinder, Rapid CO₂ provides cylinder testing and requalification services.

The Bottom Line

So when you need a refill:

Keep your cylinder out of the heat, bring it in, and get back to using your CO₂.
