In many industrial and laboratory processes, precise cooling is essential – but using liquid coolants can be costly, messy, or even hazardous. That’s where the KAGER COLDER cold air gun comes in: a clean, efficient, and maintenance-free solution for targeted ultra-cold airflow powered by compressed air.
Clean cooling through Joule-Thomson physics
The KAGER COLDER operates on the Joule-Thomson principle, where compressed air expands rapidly and produces an intense cold air stream (as low as -55 °C) – without electricity or refrigerant gases. This makes it a powerful, eco-friendly alternative to liquid coolants in production, assembly, or lab environments.
Compact and versatile for every application
Thanks to its slim design, magnetic holder, and flexible tubing, the COLDER can be precisely positioned – even just 20 mm from the surface. It’s ideal for electronics, metal machining, soldering, welding, or temperature testing – all without sticky residues or corrosion risks.
Adjustable cold, stable performance
Available in four models with air flow rates from 45 to 600 l/min, the COLDER allows easy adjustment of the outlet temperature using a set screw. Under constant input conditions, the temperature remains highly stable – with only ±0.6 °C fluctuation.
A clean and sustainable cooling solution
By replacing liquids with air, the COLDER offers:
✅ No contamination
✅ No disposal issues
✅ No corrosion risks
✅ Perfect for dry processing or lab use
