77R1642 Condenser Assembly – 3 Fan Skirt-Mount (Bus / Heavy-Duty HVAC)

The BTRAC 77R1642 Condenser Assembly supports reliable cooling in demanding mobile HVAC environments. It uses a micro-channel condenser coil, which improves heat transfer while reducing overall weight. As a result, the system delivers strong cooling performance without adding unnecessary load.

This condenser features three 12-inch SPAL fans, which move air efficiently across the coil. Together, the fans provide 2,250 CFM of airflow, helping maintain stable head pressures even in high-ambient conditions. In addition, the assembly draws 23 amps at 13.6 VDC, which supports consistent electrical performance in heavy-duty systems.

The skirt-mount design allows this unit to bolt directly into many existing installations. Because of this, technicians can replace worn or damaged condensers without modifying mounting structures. The unit also includes plug-and-play electrical connectors, which simplifies installation and reduces service time.

For durability, the condenser assembly uses zinc-coated components to help resist corrosion. Therefore, the 77R1642 performs well in transit, shuttle, and vocational applications where exposure and vibration are common.
