Making sure the refrigeration chain remains unbroken is a high priority in airline catering. For flights departing from Italian airports, this job is normally entrusted to dry ice from Asco Carbon Dioxide Ltd. In a turnkey project for DMH, Italy’s biggest dry ice manufacturers for catering purposes, Asco has installed a complete dry ice plant. DMH’s Rome and Milan facilities each produce eight tonnes of dry ice per day for their airline catering customers.
