Commercial Milk Steamers Built for Cafés That Never Slow Down
Fully automatic steam machines that free your barista from wand work.
A commercial milk steamer is a standalone machine that heats and froths milk automatically, without a barista using a steam wand. Wpm's Prosteam V2 has an 800ml tank.
A commercial milk steamer takes the wand work out of a busy service line: fill the tank, set the temperature, and the machine froths a jug on its own while your barista pulls the next shot. We've supplied Sydney cafés since 1999, and we know the difference between a unit that earns its place on a bench and one that just takes up space. This is the standalone side of milk steaming, not the wand built into your machine.
Every espresso machine with a boiler has a steam wand: a metal pipe that releases pressurised steam so a barista can texture milk by hand, judging temperature and foam by feel.
Wand, Frother, or Standalone Steamer
A milk frother, or coffee frother, is the broader term for anything that aerates milk, wand included. A commercial milk steamer is different again: a self-contained unit with its own boiler, tank, and thermostat that automates the job entirely. As café milk drinks grew larger and more frequent, kitchens needed more steaming capacity than one machine's wand could reasonably deliver during a rush, which is why a dedicated milk steamer earns its place next to the espresso machine rather than replacing it. Milk chemistry sets the ceiling on all of this: milk proteins froth up to around 77°C, and once you cross that point the milk stops taking on air no matter how good the equipment is. That's true whether you're on a hand-held wand or a fully automatic machine like the Wpm Prosteam, which is exactly why an accurate, repeatable target-temperature setting matters more than raw power. Coffee Parts is the Australian home for Wpm's coffee milk frother range, sitting alongside the espresso machines whose wands do the same job on a smaller scale.
Wand or Standalone: How to Decide
Choosing between a wand and a dedicated commercial milk steamer comes down to volume and headcount, not budget alone. If one barista is already flat out pulling shots, a second steaming station removes the single biggest bottleneck in service: someone standing at the machine texturing milk while the queue grows. A home kitchen without a plumbed-in machine, or a small office break room, gets the same benefit at a smaller scale: milk that's ready without anyone learning wand technique.
Wpm Prosteam V2 Specifications
The Wpm Prosteam Automatic Milk Steam Machine V2 is Coffee Parts' current standalone option, now in a matte black finish and, per Wpm, faster and more powerful than the original Prosteam. Here's what to weigh:
| Factor | Wpm Prosteam V2 |
|---|
| Water tank | 800ml |
| Operation | Fully automatic |
| Temperature control | Target temperature adjustable, accurate to +/-1 degree |
| Shutoff | Steam generation stops automatically once target is reached |
| Finish | Matte black |
That automatic shutoff is the detail worth getting dialled in for your setup: it's what lets a unit run unattended on a busy counter instead of needing someone to watch the jug. If you're weighing this against simply adding a second espresso machine for the extra wand, the steamer is the cheaper, smaller-footprint fix when what you actually need is more steaming capacity, not more shots. It won't pull espresso, so it's a companion to your existing machine rather than a replacement for it.
Stock, Alternatives, and What It Won't Do
One honest caveat: the Prosteam V2 is currently out of stock online. We'd rather tell you that upfront than have you find out at checkout, and we can flag you when new stock lands. In the meantime, if you're comparing a standalone unit against a coffee machine with milk frother built in, the built-in route suits a single-drink-at-a-time home setup better; the standalone route suits anywhere pouring more than a few milk drinks back to back.
A commercial milk steamer earns its keep alongside the rest of your setup. We'd pair the Prosteam with: a set of milk jugs sized to your tank fills, a descaling routine using our coffee machine descalers to protect the internal boiler from scale, and filtered water. Water filtration isn't optional on any machine with its own boiler: hard tap water scales the element and shortens its life. We're an Australian distributor of BWT water filters, the official Water Filtration Sponsor of the World Coffee Championships since 2022, and we'll help you match a filter to your tap water.
Coffee Parts wasn't built around milk steamers specifically. It was built around parts and machines generally, but the logic is the same one my dad applied to every espresso machine he ever pulled apart: the bottleneck in a busy café is rarely the coffee, it's whoever's stuck at the steam wand. A dedicated steamer is a workflow fix as much as an equipment one. We've been having that conversation with café owners since 1999, and it hasn't changed much. — Pedro Lara

Frequently Asked Questions
What is a steam wand?
+
A steam wand is the metal pipe on an espresso machine's boiler that releases pressurised steam so a barista can texture milk by hand. It's built into the machine, not a separate appliance, and getting a good result depends on the barista's technique as much as the equipment.
Is a steam wand the same as a frother?
+
No. A frother is the umbrella term for anything that aerates milk, and a steam wand is one type of frother. A commercial milk steamer, like the Wpm Prosteam, is a different type again: a standalone unit that does the job automatically instead of by hand.
What's the difference between frothing milk by hand and using an automatic milk steamer?
+
Doing it by hand takes practice: judging pitcher position, temperature, and foam texture by feel. An automatic steamer like the Wpm Prosteam removes that skill requirement. Fill the 800ml tank, set the target temperature, and the machine stops on its own once it gets there.
Is the Wpm Prosteam V2 suitable for a busy café?
+
It's built for that job: fully automatic operation and an adjustable target temperature mean it can run unattended on a counter, which is exactly what a second steaming station during a rush needs. Wpm says the V2 is faster and more powerful than the original Prosteam.
How do I stop the nozzle from clogging with milk residue?
+
Release a short burst of steam into the drip tray straight after frothing, before any residue can dry and block it, then wipe the nozzle down. This is standard practice across steam equipment, and it's worth building into your close-down routine every time.
Will a standalone steamer work alongside my existing espresso machine?
+
Yes. A commercial steamer is a separate, freestanding appliance with its own water tank, boiler, and power lead, so it sits next to any machine rather than connecting to it. That's what makes it a way to add steaming capacity without buying a second espresso machine.
Is the Wpm Prosteam in stock right now?
+
It's currently out of stock online. We'd rather say that plainly than have you find out at checkout. Check the product page for the latest lead time, or get in touch and we'll let you know as soon as new stock is confirmed.
