Factory Direct Sale Portable Ultra Low Temperature Freezer with Secop Compressor

You’re looking at a 25-liter portable ultra-low temperature freezer that hits -60 to -80°C, and it’s built around a Secop compressor—same guts you’d find in many benchtop units that cost twice as much. The inner chamber is 304 stainlss steel, which matters because biological residues clean off easier than with coated alumnum, and we’ve used it for vaccine storage during field trials where power was intermittent.

It’s reliable mostly because of compnent choices: that Germany Ebm fan keeps condenser temps stable, and the Spain Keld thermostat holds setpoint within a couple degrees even when ambient hits 30°C or so. The audible and visual alarm isn’t just a buzzer—it triggers on both high and low deviations, which saves samples when someone forgets to close the lid properly. We usually have stock, but confirm lead time if you need more than 10 units.

One thing that catches buyers off guard is the power input—270 watts on DC12/24V means you’ll need a decent battery bank if you’re running it off-grid for more than 8 hours. It’s not suited for long-term storage of large cryovial racks (the 327x220x305mm inner size fits about 4 standard freezer boxes stacked), but for transport or backup of critical vaccines, it’s basically a workhorse.

Can you trust us? We’ve shipped these under CE cerification for about three years now, and teh plywood transport box is overkill—we’ve had units survive forklift drops without damage. The refrigerant is fluorine-free, which is a compliance detail some labs need for green procurement policies, though it’s not a performance differentiator. Anyway, the MOQ is typically 1 unit for sample testing, but we prefer 5-10 for.
