The BTRAC BT7-6357 condenser coil is designed for mobile air conditioning systems used on Mack truck applications, including Mack Vision model years 2007–2008. It features a parallel-flow, non-serviceable condenser design that supports efficient heat rejection while maintaining stable refrigerant pressures during on-highway operation.
Because the condenser uses Volvo-style pad inlet and outlet fittings, it connects directly to OE pad-mounted hose assemblies. As a result, installation remains clean and consistent without the need for adapters. In addition, the parallel-flow construction improves heat transfer efficiency compared to older tube-fin designs, which helps the system maintain steady cooling under load.
The aluminum core construction balances strength and weight while supporting dependable thermal performance. As a result, the BT7-6357 performs reliably in R12 and R134a refrigerant systems, especially in fleet and vocational truck applications where uptime and cooling consistency matter.
Furthermore, this condenser serves as a direct replacement for OEM number 210RD517M, which simplifies sourcing and reduces downtime during service or repair.
