Mini Cooler™

Cool small parts and tools with clean, cold air.
Prevent burning, melting or breakage!

What is the Mini Cooler?

A proven way to reduce downtime and increase productivity on a variety of operations involving small parts where heat is a problem. EXAIR’s Mini Cooler produces a stream of -7°C (20°F) cold air to prevent heat build-up. The Mini Cooler is particularly effective on high speed operations to prevent burning, melting and heat related breakage. Operation is quiet (76 dBA) and there are no moving parts to wear out.

How the Mini Cooler Works

The Mini Cooler incorporates a vortex tube to convert a small amount of compressed air into two low pressure streams, one moving within the other in opposite directions. The two airstreams exchange heat, producing cold air from one end of the tube and hot air from the other. A flexible hose directs the cold airstream at the surface to be cooled.

Accessories

Filters, Regulators, Valves & More

With proper filtration of dirt, moisture and oil from the compressed air supply, EXAIR compressed air products will operate for years with no maintenance required. Use a 5 micron or smaller filter separator on the compressed air supply. To prevent problems associated with oil, use a 0.03 micron or smaller oil removal filter on the compressed air supply. Pressure regulators permit easy selection of the operating pressure, providing infinite control of flow, force and air consumption.
