Mobile cool rooms for sale, built around your work
Choose the size, the temperature range, the layout, the doors and the fit-out. Every cool room trailer is built new, to order, by a commercial coolroom team with 15+ years in the trade.
Indicative builds from $14,999 ex GST · not a quote, your specification sets the real number
No model number needed. Describe the job and we come back with a specification and a price for it.
How a build gets specified
Ring with the job rather than a model number. We ask what the room has to hold, how you load it and where it sits when it is working, and build the specification out of your answers.
Describe the job
What goes in it, how much, how you load it, and where it has to work.
Agree the specification
Size, temperature range, layout, doors and fit-out, settled before anything is priced.
Get the quote and we build it
The quote covers the specification you agreed, so the number is for your job.
Collect it, or we deliver
Delivery is quoted separately and is not in the indicative price above.
If a permanent installation would suit the job better than a trailer, you will hear that before you commit to anything. The same company builds those too.
Building rather than hiring? Select Coolrooms & Construction handles coolroom construction and installation.
What people buy one for
Owning suits some situations and not others. These are the ones that come up.
It goes out on a schedule
Markets, festivals, a food truck with a regular pitch. Once cold storage is on the roster every week, hiring stops adding up and owning starts to.
The cold storage stopped being enough
Trade grew, orders grew, and the room is full by Thursday. A trailer adds space you can park where it is useful, without rebuilding the back of the shop.
Cold storage that moves
Caterers and event crews need the room where this week's work is. On a trailer it follows the job.
Farm and property use
Produce, meat and anything else held cold on a property where a permanent build does not suit the site or the season.
Construction and site work
Cold storage that turns up with the plant and leaves with it, and is there for the next job rather than booked out by someone else.
Replacing a rental that never ends
Two years of hire invoices add up to a number worth putting next to the cost of a build. Plenty of buyers arrive that way.
Buy from the people who build it
A trailer on a marketplace listing was built to suit whoever ordered it. You inherit their size, their door and their fit-out, and however hard they worked it. Yours gets specified around your job and built new, so its service history starts on the day you take delivery.
The people who built it are the ones who answer the phone afterwards. Select Coolrooms & Construction has spent 15+ years building coolrooms, freezer rooms and clean rooms for commercial sites across Sydney, Newcastle and Wollongong, out of the same Penrith workshop that builds the trailer. Ring about an adjustment six months later and you are talking to whoever did the work.
Its day-to-day work is commercial construction: walk-in coolrooms and freezer rooms built from EPS-FR and PIR insulated panels, clean rooms finished to ISO classifications, plus insulated doors, growing sheds, modular rooms and partition walls. A coolroom on a trailer is a smaller version of the same trade.
Woolworths, DHL, Arnott's and Aldi are among the names the company has built for. That work is commercial rooms rather than trailers, but it is the same crew and the same standard, scaled down to something you can tow, and it is why the trade knowledge behind this one runs deeper than a trailer yard.
Below is that work: finished commercial coolrooms, and a build partway through with a scissor lift and forklifts on site. Permanent rooms rather than trailers, and the reason a trailer built here holds temperature and finishes properly.
What a custom build costs
Two jobs that sound alike on the phone can specify out to different builds. Here is the unit already built, as a reference point for the money and the size.
- Size
- 3m x 2m
- Height
- About 2.5m, outside the panels
- Holds down to
- 2 degrees
- Power
- Standard 10 amp outlet, with a lead run out to it
- Indicative from
- $14,999 ex GST
The height is measured outside the panels, so the usable space inside is smaller. The price is a starting point to give you a sense of the money. It is not a quote and it does not include delivery.
What a trailer this size usually carries
The figures below are not Select Coolrooms & Constructionspecifications and not a quote. They are what other Australian builders publish for a trailer of roughly this footprint, read from their own pages in August 2026, so you can scope a job before you ring. Your build's own figures come with your quote.
| Axles | Tandem at this size. Single axle is the norm on the smaller classes |
|---|---|
| Brakes | Mechanical or override brakes. All-wheel brakes plus a breakaway system become mandatory above 2,000 kg GTM |
| Plated weight | Around 2,000 kg ATM. The class clusters deliberately just under the 2,000 kg brake threshold |
| Panel | 50 mm to 100 mm on trailer builds, with the 100 mm class reserved for freezer-rated units |
| Internal height | Around 2.0 m to 2.1 m once the panel thickness comes off |
| Power inlet | A 240V 15 amp inlet is close to universal. The unit above runs on a standard 10 amp outlet |
| Temperature | Chiller-only units sit around 0 to 5 degrees. Freezer capability comes from freezer-rated panel and a freezer-rated unit, specified at build time |
| Shelving, meat rails, pallet doors | Usually priced as options rather than included |
| Registration | A trailer built since 1 July 2023 needs an entry on the Commonwealth Register of Approved Vehicles before NSW will register it |
The buying guide has the wider market picture and the towing, weight and brake rules behind these numbers.
We specify every trailer before we price it, so your quote covers the size, temperature range, layout and fit-out the job needs. Describe the job and you get a figure for that build. One call covers it.
Need one for a short job? Hire instead
A breakdown, a fitout or a one-weekend gap is what hire suits. We deliver the trailer, set it up, check it is holding temperature and collect it at the end. It goes out from the Penrith workshop, and Newcastle and Wollongong are both inside the run.
It is one trailer at coolroom temperatures, so dates are worth checking before you plan around it. The hire page has the delivery list and how a booking works.
Questions buyers ask
How much does a mobile cool room cost to buy?
Indicative builds start from $14,999 ex GST, and that figure is a reference point rather than a quote. It does not include delivery. Size, layout and fit-out all move the number, so the price follows the specification. The already-built unit is set out under what a custom build costs.
Do you sell them ready-made or build to order?
Built to order. There is no stock list to choose from, because size, temperature range, layout, doors and fit-out are all specified per job.
Can you build a freezer trailer, not just a coolroom?
Yes, on a custom build. Temperature range is one of the things built to your specification. The hire trailer is the exception: it is one fixed unit at coolroom temperatures only.
Who builds them?
Select Coolrooms & Construction, the Penrith company behind this site. You are buying from the builder, not a reseller or a marketplace listing. The section above, buy from the people who build it, sets out what else the company builds.
Can I hire one instead of buying?
Yes. A short job suits hire; a need that keeps coming back is where buying starts to make sense. Details are on the hire page.
Do you sell second-hand units?
No. We build and sell new units to order. If you are comparing used trailers, the buying guide sets out the weights, brakes, tow ratings and registration details worth checking before you commit to one. It is here: the mobile coolroom towing, weight and power guide.
Is a cold room the same as a cool room?
Yes. Cool room, coolroom and cold room all describe the same thing, and people use more names again once it is on a trailer: coolroom trailer, refrigerated trailer, portable cool room. All of them mean one product, an insulated refrigerated room mounted on a trailer.
Tell us what the trailer needs to do
You do not need a model number or a finished specification. Tell us what you need to keep cold, how much space it takes, where the trailer will work and when you need it, and we will turn that into a build specification and a quote. Call if that is quicker.
