There use to be a device offered for milling machines that made very cold air using the expansion of the compressed air to chill the blast - not seen them offered recently - anyone know what I'm on about?
(back in the late 60's I used 'mini-coolers' that produced liquid air to cool infra-red detectors in satellites - source was 4000 psi air - so it's an oldish established technology)
