Most cordless oxalic acid vaporisers look alike on paper. They run on 18 V power-tool batteries, they sit in the same power bands and they cost much the same.
The differences show up in the apiary: how the vaporiser gets into your hive, what happens when residue builds up in the pan, and whether a worn part means a quick repair or a whole new unit. That is where OXALIKA pulls ahead, and this guide explains why.
Which OXALIKA Suits Your Apiary?
The OXALIKA cordless range is built on two platforms, plus a mains-powered model for very large operations:
- OXALIKA MINI Sprint: the compact 150 W vaporiser, designed for beekeepers with up to about 50 hives.
- OXALIKA PRO Sprint: the 240 W professional platform, for apiaries of around 50 hives or more.
- OXALIKA PRO Smart: the PRO Sprint with the Smart Valve fitted, so you can load the next dose while the current one vaporises.
- OXALIKA PRO Power: a 600 W mains-powered unit for commercial operators, where even a few seconds per hive add up.
Every Sprint and Smart model uses an adjustable plunger doser, set from 1 to 4 g with a turn of the knob.
OXALIKA PRO vs Other 250 W Vaporisers
In the professional cordless class, the OXALIKA PRO (240 W) and other 250 W vaporisers have similar basic performance. Both run on 18 V lithium-ion batteries. The differences are in the design:
| Feature | OXALIKA PRO | Other 250 W vaporisers |
|---|---|---|
| Power | 240 W | 250 W |
| Battery | 18 V Li-ion | 18 V Li-ion |
| Nozzles | Three interchangeable nozzles included | Single nozzle with fixed geometry |
| Ways into the hive | Entrance, side hole or from above | Mainly through a dedicated hole |
| Boiler access | Direct, without dismantling the vaporiser | Only after dismantling the unit |
| Mechanical cleaning | Immediate | Possible, but needs disassembly |
| Battery platform | Replaceable adaptor | Battery type fixed when you buy |
| Smart Valve | Available (PRO Smart) | Not available |
OXALIKA MINI vs Other 150 W Compact Vaporisers
In the compact class the gap is wider, because it comes down to how the boiler is built:
| Feature | OXALIKA MINI Sprint | Other 150 W vaporisers |
|---|---|---|
| Power | 150 W | 150 W |
| Nozzles | Three interchangeable nozzles | Single straight nozzle |
| Ways into the hive | Entrance, side hole or from above | Mainly through a dedicated hole |
| Boiler access | Direct, without dismantling the vaporiser | Inner part press-fitted and can't be reached without damaging the unit |
| Mechanical residue removal | Yes | Complete mechanical cleaning not possible |
| Battery platform | Replaceable adaptor | Battery type fixed when you buy |
| Thermal insulation | Included as standard | Not included |
Comparisons are based on the manufacturers' published technical information for other vaporisers in the same power class as at November 2026. Specifications can change.
Three Nozzles, Three Ways Into the Hive
Every OXALIKA Sprint and Smart vaporiser comes with three interchangeable nozzles in the box:
- Straight nozzle: treats through a dedicated hole drilled in the hive wall. It's the usual setup on single-nozzle vaporisers.
- Entrance nozzle: the tube drops down to the level of the floor, runs along it and finishes with the tip angled slightly up. It slides into hives with very low entrances, and the upturned tip sends the vapour up into the colony instead of along the floor.
- Top nozzle: treats from above, through a feeder hole or a hole in the roof. This matters with plastic and polystyrene hives, where you don't want the hot body of the vaporiser touching the hive. Only the tube goes in; the vaporiser sits on top, on a small timber board if you need a stable, heat-safe base. You don't have to hold it at an angle for the whole treatment.
If you run a mix of timber and Apimaye or poly hives, one vaporiser covers them all.
A Boiler You Can Actually Clean
This is the biggest practical difference, and it matters in Australia in particular.
Oxalic acid products don't all vaporise cleanly. Some oxalic acid products contain other ingredients, and formulations like this can leave a crust in the vaporiser pan as you work through your hives.
Rinsing with water removes soluble residue, but not everything left behind is water-soluble. On an OXALIKA, the boiler stays directly accessible. You can look inside, scrape it out and get back to work, without dismantling anything.
On some other designs the boiler can only be reached by taking the vaporiser apart. On some compact models the inner part is press-fitted and can't be opened at all without damaging the unit, so it can never be fully cleaned.
Built to Be Serviced, Not Thrown Away
OXALIKA vaporisers are not sealed units. They are designed to be taken apart so individual parts, including the electronic board, can be replaced, usually in a few minutes. A worn seal or a damaged doser shouldn't mean buying a whole new vaporiser.
We stock the common OXALIKA spares, such as the Sprint plunger dispenser, the graduated adjustment sleeve and replacement O-rings.
OXALIKA vaporisers come with a 2-year standard warranty.
Change Battery Brands, Keep Your Vaporiser
OXALIKA cordless vaporisers connect to your battery through a replaceable adaptor. We carry adaptors for Milwaukee M18, Makita LXT and DeWalt XR 18 V batteries.
The battery brand you choose today doesn't lock you in. If you change tool brands later, you change the adaptor, not the vaporiser. On some other cordless vaporisers, the battery type is fixed when you buy the unit.
The Smart Valve: Load While You Vaporise
The PRO Smart is a PRO Sprint with an extra valve between the doser and the boiler. During vaporisation the valve closes the passage to the boiler, so:
- the doser isn't sitting directly over the hot boiler, so it stays cooler;
- you can load the next dose while the current one is still vaporising.
Take the Smart Valve off and the vaporiser works as a standard Sprint again. You choose how you want to work without buying a second machine.
Electronics Made for the Job
OXALIKA designs its control electronics for this one application rather than adapting generic parts. The cordless models use PT100 platinum temperature sensors, a type widely used in industry because they hold their accuracy over time. The common alternative, the NTC thermistor, is sensitive and accurate when new but tends to drift more with repeated heating and cooling. A vaporiser goes through thousands of heat cycles, so long-term stability counts.
Depending on the model, the electronics also give you status indication and automatic protection against over-discharge, which looks after your power-tool batteries too.
All OXALIKA cordless vaporisers have carbon-fibre thermal insulation around the boiler. It cuts heat loss and reduces the effect of wind and cold mornings on battery use, which helps when you're treating through autumn and winter.
Speed and Battery Life: An Honest Look
As a guide, under normal conditions:
- MINI: about 40–50 seconds per 2 g dose
- PRO: about 25–30 seconds per 2 g dose
These are deliberately conservative figures. Real times depend heavily on your battery: its output, charge, condition and temperature. A high-output professional battery such as a Milwaukee M18 will be noticeably quicker than a light-duty DIY battery.
To be fair to other brands: vaporisers in the same power class use about the same amount of battery per treatment, and they sell at similar prices. Some cordless vaporisers with more power vaporise a dose faster, but they use more battery per hive to do it. Vaporising is only one part of the job anyway; you're also walking between hives, positioning the unit and loading each dose.
If you run 1000 or more hives every second counts; the 600 W mains-powered OXALIKA PRO Power is the perfect tool.
So OXALIKA isn't the cheapest option and doesn't claim to be. What you're paying for is the design: nozzle choice, a boiler you can clean, swappable battery adaptors, parts you can replace and electronics built to last.
Using an Oxalic Acid Vaporiser in Australia
Whichever vaporiser you use, the rules are the same. Use a product permitted by the APVMA, such as Api-Bioxal powder under permit PER94609 (NSW, ACT, VIC, QLD and SA), follow the permit label, keep your treatment records and wear proper protection: a respirator rated for acid vapour, eye protection and gloves.
For doses, timing and a full step-by-step, read our Varroa Mite Treatment guide. Before and after you treat, check your mite load with a Varroa Checker so you know the treatment worked.
Frequently Asked Questions
Which OXALIKA vaporiser should I buy?
For up to about 50 hives, the MINI Sprint does the job. From around 50 hives up, the PRO Sprint is faster per dose. If you want to load the next dose while vaporising, choose the PRO Smart. For large commercial operations with mains power available, look at the 600 W PRO Power.
Do OXALIKA vaporisers come with a battery?
No. They run on 18 V lithium-ion power-tool batteries, which you supply. You choose the adaptor for your battery brand, and you can swap it later if you change brands.
Can I use an OXALIKA vaporiser on a polystyrene or plastic hive?
Yes. Use the top nozzle through a feeder hole or a hole in the roof, so only the tube enters the hive and the hot body of the vaporiser stays off the hive surface. A small timber board under the vaporiser gives it a stable, heat-safe base.
How do I clean the boiler?
The boiler is directly accessible, so you can inspect it and clean it mechanically without taking the vaporiser apart. This matters when your oxalic acid product leaves residue that water alone won't remove.
Can I add the Smart Valve to a PRO Sprint later?
The PRO Smart is a PRO Sprint fitted with the Smart Valve, and the valve can be fitted or removed without replacing the vaporiser. Call us on 1800 BEEWISE to check parts availability for your unit.
Choose a Vaporiser That Lasts
Most vaporisers will vaporise oxalic acid. The real question is which one still works well, and can still be repaired, after several seasons of treatments.
Three nozzles. A boiler you can clean. Adaptors that follow your batteries. Parts you can replace. Browse the OXALIKA range or call the team on 1800 BEEWISE for help choosing the right model.
