Description
The Comfort-Aire MCK042AGC30C0PS is an MC Compact Series water-source heat pump designed for commercial zones where capacity, efficiency, and service visibility are non-negotiable. On a water-loop system, the MCK042AGC30C0PS gives you dependable zone-level heating and cooling with a compact cabinet designed to fit real mechanical constraints in offices, schools, medical spaces, retail buildouts, and institutional environments.
MC Compact Series units use low-GWP R-454B refrigerant and are positioned to exceed ASHRAE 90.1 efficiency standards. The coaxial heat exchanger and TXV metering help hold performance steady as loop temperatures vary, which supports more predictable comfort and easier system tuning across multiple zones.
Occupied-space comfort is supported with sound-absorbing glass-fiber insulation and double-isolation compressor mounting—details that reduce vibration transfer and operational noise, especially important in offices and clinical environments.
Controls are built for commercial operation and faster troubleshooting: microprocessor controls with emergency shutdown, Unit Performance Sentinel performance monitoring, CXM2 communicating controls capability, and an external connection path intended to reduce commissioning and service time. RDS is available as an option in this size range when required.
