Certified, reliable, space-saving
The challenge: harsh environmental and operating conditions
Air conditioning units and air distribution systems in rail vehicle applications must ensure
passenger comfort at all times. These systems are subject to special conditions: vibrations,
extreme temperature fluctuations, special safety and fire protection regulations and confined
spaces. To accomplish their task under these demanding conditions, they must have
components that are precisely tailored to applications in rail vehicles. All components and
materials must be certified in accordance with application-specific standards, must function
reliably under harsh conditions and must be as compact as possible.
