3 Tools for Spot Cooling

/ / Air Solutions, Vortex

Spot Coolers are units that can be positioned strategically to cool “hot spots.” Most often used for cooling of metal parts, in the machining and repair of metals, plastics, wood, ceramics and other materials. Cold air machining outperforms mist coolants and substantially increases tool life and feed rates on dry machining operations. There are 3 main tools used for spot cooling:

  • Vortex Tubes: Able to produce up to 6000 BTU/hr of refrigeration and temperatures as low as -40 deg a vortex tube creates a vortex from compressed air and separates it into two air streams – one hot and one col
  • Cold Air Guns: With no moving parts to wear out, cold air guns require no electricity at the target, just compressed air to deliver powerful cooling. By using the concept behind Vortex tubes, cold air guns deliver sub-freezing air for dry machining and spot cooling, in a low cost package.
  • Cold Air Pistol’s: Cold Air Pistol’s use vortex tube technology and filtered compressed air to produce sub-freezing air as low as -30 deg F. With no moving parts to wear out, cold air pistols offer an ergonomic and economic alternative for intermittent spot cooling.

The effective cooling from a Cold Air Gun can eliminate heat-related parts while improving parts tolerance and surface finish quality.
