Provide a pleasant indoor climate with energy-efficient bus & train air conditioning

Train operators understand providing a pleasant indoor climate for their entire journey has top priority no matter the outside weather conditions and the number of passengers.

To meet the demanding requirements for both comfort and high reliability for train air conditioners and bus air conditioning applications, the air conditioning system must be designed considering a wide cooling capacity range and incorporating vibration-resistant components.

In addition to passenger comfort and system reliability, efficient use of energy is another important design factor for the train operator. As a result, lightweight, compact components must be considered for use throughout the system design for transport air conditioning.

Danfoss offers solutions and train- and bus air conditioning parts for reliable, energy efficient air conditioning systems that help ensure a comfortable journey for passengers, and ensures energy-savings as well.
