Two things called an ice barrel
Before anything else, split the word. If you landed here looking for a catering tub to hold ice and bottles at a party, that is not what we make — and the first row of the table below will save you reading the rest. If you are sourcing a sparkling water dispenser, the second row is your part of the machine.
| What people mean | What it is | Who makes it |
|---|---|---|
| Party / catering ice barrel | An insulated tub, usually with a lid and a tap, filled with ice and bottles for serving drinks | Catering and houseware suppliers — not us |
| Ice barrel inside a soda maker | The chilled water reservoir that holds water at serving temperature before it is carbonated and poured | Us — it is a core part of DRINKSIT |
Suppliers use several names for the second one: ice barrel, ice bath, cold tank, chilled reservoir, cooling barrel. They describe the same job.
Why the cold matters more than the barrel
A gas dissolves into a liquid more readily the colder that liquid is. Water held near 4 °C takes up more CO₂ than water at room temperature, and it holds on to it longer once it is in the glass. That single fact is where our name comes from: at 4 °C, carbon dioxide and water meet at their best.
So a chilled reservoir is doing two jobs, not one. It gives you a cold drink, and it gives you bubbles that are still there at the end of the glass. A machine that carbonates warm water and then chills it is working the other way round, and you can taste the difference.
What to specify on a chilled dispenser
Seven questions decide whether the machine is pleasant to live with. The right-hand column is what our own counter-top unit, DRINKSIT, answers — published so you have something concrete to compare against, not so you copy it.
| Specify this | Why it matters | DRINKSIT |
|---|---|---|
| First chill time | The one-off wait before the first cold glass | About 45 minutes from room temperature |
| Serving temperature | How cold the finished drink is, and how long it stays there | Ice water from 12–25 °C, electronic (semiconductor) cooling |
| Sparkling at room temperature | Whether the machine is usable before the tank is chilled | Yes — same unit, same three carbonation levels |
| Throughput | How many glasses per hour, and whether it keeps up at dinner | Up to 10 litres an hour |
| Glass size | How much comes out per press | About 220 ml, poured straight into your own glass |
| Tank and filter | Refill effort and water quality | 2.8 L removable tank, takes a Brita-type filter |
| Cleaning | The job nobody wants every morning | Hold the first button five seconds and it rinses its own lines |
Where the gas sits, and why it is a separate question
The cold side is only half of a dispenser. The other half is the CO₂: cylinder format, valve standard, and whether the gas can ship in the same carton as the machine. On DRINKSIT the 0.6 L cylinder mounts at an angle, so changing it does not mean wrestling with the machine, and we are certified under both TPED and DOT so the cylinder can travel with gas in it.
Four patent applications cover the machine — one invention and three utility models, covering the carbonation chamber, its cooling airflow duct, the sealing parts and the solenoid control valve — all accepted by the patent office on 15 September 2026. The patent list is downloadable if you want to read them.
The words buyers use, in one place
| Term | What it refers to |
|---|---|
| Ice barrel | Either a catering tub, or the chilled reservoir inside a dispenser — context decides |
| Ice bath | The same reservoir, named for how it cools |
| Cold tank / chilled reservoir | The same part again, in engineering language |
| Carbonation chamber | Where the CO₂ meets the water — cold side and gas side meet here |
| Counter-top dispenser | The whole machine: tank, cooling, carbonation, pour |
If you are also choosing the machine
The chilled dispenser is one line of sixteen. If you want to see the rest — the mix-and- carbonate machines that sparkle juice, coffee and whole fruit, the classics, the portable line — start from the products page, which is organised by the problem each model answers rather than by model number.
And if what you actually need is this machine with your brand on it, that is a different conversation: see soda maker OEM & ODM.
