Description
The Comfort-Aire MCT042AGC30C0PS is an MC Compact Series single-stage water-source heat pump designed for commercial zones where capacity, noise control, and service visibility matter. It’s a strong fit for larger office zones, retail footprints, classrooms, medical facilities, and institutional spaces served by a water loop, where operators want stable performance and simpler commissioning.
The MC Compact Series exceeds ASHRAE 90.1 efficiency standards and uses R-454B low-GWP refrigerant. Internally, the platform relies on a coaxial heat exchanger and TXV metering device to maintain stable heat transfer and refrigeration control as water-loop temperatures and loads vary.
Service and diagnostics are a core part of the value proposition. Microprocessor controls with emergency shutdown, Unit Performance Sentinel monitoring, and standard safety features help support uptime. CXM2 communicating controls provide real-time operating condition visibility and captured fault conditions, and the external connecting port reduces service tool connection time.
