Lumikko delivers complete solutions for demanding passenger car ventilation. The frequently varying number of people in passenger cars and the changing environmental conditions set exceptional demands for ventilation and temperature control. The situation is managed by Lumikko Control system, which has been especially developed for rolling stock. Passenger cars must have a large air circulation, in changing conditions, delivered without the feeling of drafts, which would reduce travel comfort. The system must operate reliably at great speeds and eliminate the effects of environmental pressure shocks to the car. In addition to passenger car and driver cabin ventilation, Lumikko also supplies the duct systems, piping and heating components.
