X-CTH is a volumetric operating machine, where all the components in contact with the process fluid are constructed in stainless steel (AISI 316). The high resistance of this material to corrosion makes X-CTH suitable for use in heavy-duty applications, where air and vapours are conveyed. Two direct current electric fans (24V) provide forced cooling of the compressor: the conveyed air goes through the benches following a ducting system designed to reduce the oil temperature (on average -35°C), preserving its features over time. The cooling system is patented. The noise level is low thanks to the gradual adjustment system of pressure to discharge. X-CTH does not emit oil in the atmosphere and requires low maintenance.
