Hi-Velocity RCM-100-A2L (R-454B/R-32) TX Refrigerant Module w/ RDS Kit Refrigerant Coil
The RCM-100-A2L (R-454B/R-32) TX Refrigerant Module w/ RDS Kit is the R-454B / R-32 (A2L) configuration of the RCM-100 Refrigerant Cooling Module — a heat-pump-ready TX cooling coil designed as an add-on to an existing Hi-Velocity air handler. Mounts on the return-air side using two L-mounting brackets, with its own drain pan and dual 3/4" drain connections. Rated for 3.5–5.0 tons of cooling (42–60 MBH). Ships with the RDS Kit (mitigation board + refrigerant sensor) required for A2L installations.

Applications
The RCM series is the retrofit cooling upgrade for an already-installed Hi-Velocity air handler — L-mount brackets allow attachment to the return-air side without dismantling the base unit. For new-build installations where cooling is specified up-front, the RBM base module is typically the cleaner mechanical solution.
