This air conditioning condenser package is designed specifically for the rigors of railroad service. The package is intended for those updating, upgrading, or replacing existing air conditioning systems on railroad passenger cars, and the structure of the air conditioning condenser is designed specifically to be hung from the top of the unit under a railroad car. The package is available with several popular railroad service compressors. Unlike rectangular condenser units that are basically modifications of commercial building systems, this air conditioning condenser has a profile that is designed with under-car clearance requirements in mind when the unit is hung beneath a railroad car.

Maneurop hermitically sealed compressors come standard, as pictured above.

However, the exact same frame can also accept a Copeland Compressor:

Condenser Coil:

At the heart of this package is a condenser coil designed to survive the rigors of the railroad environment. The coil has copper fins over copper tubing that has a thicker wall than on condensers designed for stationary applications. The fins on the condenser coil are spaced close enough together to allow for good heat transfer, but farther apart than on condenser coils designed for stationary applications. This allows most undercar railroad debris to pass through the coil without clogging or coil damage. The capacity of this coil was also developed with an ambient temperature of 110 degrees F. High ambient temperature is typical in railraod car applications due to the heat from other under car equipment, plus sun heating of the track and roadbed and surrounding air.

Other Equipment:

The receiver has two sight-glasses suited for most passenger car systems. The condenser fans are made from high-strength engineered nylon with a tapered shaft hub. Condenser fan motors are of the Totally-Enclosed-Fan-Cooled type, with cast-iron frames. A built-in electrical cabinet is designed for ease of access with maximum protection from the elements. This cabinet is also equipped with terminals, a pump-down switch, and Schraeder valves, so that as much as possible maintenance crews have access to everything they need inside the box.
