COMPACT UNDER-DESK MOUNTED HVAC SYSTEMn Designed for operation in desert conditions,

while maintaining the driver’s comfortn The control panel and controller are installed outside

of the HVAC unit for easy accessn Dual refrigerant circuits for redundancy, capacity control,

and energy optimizationn Suitable for high-speed train operationn Capable of operating at extreme ambient temperatures

of up to 55 °C

COMPACT ROOF-INTEGRATED HVAC CABIN UNITn Two separate and independent refrigerant circuits

(supply for driver’s cabin and for the vestibule)

n With active pressure protection and specific housing tightness

n Integrated side channel blowers for fresh air support

n High-quality stainless steel housing, suitable for

aggressive environments

n Maintenance access from inside the driver´s cabin

HEATING, VENTILATION AND AIR-CONDITIONING In the rail sector, ergonomic working conditions are especially important for the drivers. Noise and vibration can be sources of distraction and a properly air-conditioned driver’s cab is an essential part of an efficient, healthy, and safe working environment. Knorr-Bremse’s HVAC systems ensure the right level of comfort, whether operating in mild, tropical, or even arctic conditions. Project-specific application of service-proven technologies means that systems can be flexibly configured for all vehicle types and operating environments, and always deliver the right performance with low weight, noise, and energy consumption. Available as roof-mounted or under-desk units, for newly-built vehicles or upgrades, Knorr-Bremse HVAC systems are in operation in all parts of the world – with local teams ensuring seamless service, every day.

CUTTING-EDGE TECHNOLOGIES

COMPACT ROOF-MOUNTED HVAC UNIT n Designed for operation in some of the harshest conditions, in order to assure

driver’s comfortn Remote control panel located in the crew cabin for easy accessn High reliability to support vehicle availabilityn Capable of operating at extreme ambient temperatures (above 60 °C)

SYSTEMS SOLUTIONS – BENEFITS FOR THE CUSTOMERThe more closely an HVAC system is networked with other rail vehicle sub-systems, the greater the benefit for the vehicle builder and operator, as this enables intelligent response to the other systems’ current operat-ing status. For example the HVAC unit can be immediately shut down if a fire alarm is triggered, instead of continuing to blow air into the locomotive.

HEATING, VENTILATION AND AIR CONDITIONING Passengers expect the rail sector to steadily improve levels of comfort. Noise and vibration are increasingly regarded as sources of irritation, and a properly air-conditioned interior is taken for granted. Knorr-Bremse HVAC systems ensure the right level of comfort for all passengers, whether they are commuters on urban metro trains operating in tropical conditions, or long-distance travelers in the arctic winter. Project-specific application of service-proven technologies means that systems can be flexibly configured for all rail vehicle types and operating environments, and always deliver the right performance with low weight, noise, and energy consumption. Available as roof-mounted, floor-level, or under-floor units, for driver’s cabs or passen-ger cars, for newly-built vehicles or modernizations, Knorr-Bremse HVAC systems are in operation in all parts of the world – with local teams ensuring seamless service, every day.
