BT7-0503 Condenser Coil

Description

The BT7-0503 Condenser Coil provides reliable thermal performance for transport refrigeration systems that demand consistent airflow and durability. Because it uses a high-density tube-and-fin design, it supports stable refrigerant condensation under sustained operating loads.

Additionally, this coil uses an integrated skirt-mount flange, which simplifies installation and ensures consistent alignment within condenser frames. Its balanced pass distribution promotes even refrigerant flow, while the aluminum construction helps reduce weight without sacrificing strength.

Moreover, the BT7-0503 is built for high-pressure mobile A/C systems. It supports demanding service environments and performs best when installed with proper airflow management and system cleanliness.
