Train Air Conditioner

Train operators understand that providing a comfortable indoor climate for the entire journey is a priority, no matter what the weather conditions are outside or the number of passengers.

In addition to passenger comfort and system reliability, the efficient use of energy is another important design factor for train operators. Therefore, the use of lightweight, compact components must be considered in the design of the entire transportation air conditioning system.

Features and Benefits

Expansion valve for efficient cooling at the desired temperature

Filter drier, sight glass, shut-off valve for reliable system protection and easy maintenance

Pressure switch for optimal control of compressor and fan

DC compressors are energy-efficient, stable in transportation, low-noise, and compact

Pressure regulators for crankcase, suction and condenser pressure adjustment

Microchannel heat exchanger as condenser for reduced refrigerant charge and improved corrosion resistance

Application

With our thermal management solutions for heating, ventilation and cooling, we help our customers achieve a comfortable environment. These low power - high output units are compact and can be easily installed in new and used trains, metro trams, locomotive cabs and other rolling stock or public passenger transport vehicles, automated or driverless/autonomous shuttle buses to enhance passenger and driver cab comfort.
