Vortex tubes solve spot-cooling problems. Using compressed air as a power source, vortex tubes create two air streams, one hot and one cold, with no moving parts. These tubes can reproduce temperatures form -50 to 260F, flow rates from 1 to 150 scf/m, and refrigeration up to 10,200 BTU/hr. Catalog includes technical information on these and other products.
