Product Overview
The Midea MRC Heat Pump Rooftop Unit delivers reliable dual-mode climate control for commercial facilities requiring both cooling and heating from a single, space-efficient package. Engineered for rooftop and ground-level installations, this system maintains consistent performance across diverse outdoor conditions—from summer heat to winter chill.
Built with rugged construction to withstand demanding rooftop environments, the MRC series arrives factory-charged and pre-tested to minimize installation complexity. With cooling capacities from 26 kW to 98 kW and heating capabilities up to 330,000 Btu/h, it offers scalable solutions for retail spaces, offices, warehouses, and hospitality venues.
Key Features
Coastal Deployment Without Compromise
Purpose-built for coastal environments where salt-laden air accelerates corrosion, the MRC series features 5-6x enhanced anti-corrosion treatment on the heat exchanger. Critical components include G90 galvanized steel casing and dual-coated PCB assemblies, validated through 500-hour salt spray testing equivalent to years of real-world coastal operation.
Extreme Heat Performance
Maintains operational stability in ambient temperatures up to 46°C in cooling mode, ensuring uninterrupted climate control during peak summer conditions. Optimized refrigerant management and robust scroll compressors from international brands (Copeland, Hitachi, or Danfoss) provide high-temperature reliability for mission-critical applications.
Cold Weather Heating Capability
Delivers heating capacity up to 330,000 Btu/h, operating effectively in outdoor temperatures as low as -9°C. Dual-mode operation allows seamless transition between cooling and heating based on ambient conditions, eliminating the need for separate boiler systems in many applications.
Field-Ready Installation Design
Factory-precharged and pre-tested units minimize on-site installation complexity. Vertical discharge configuration and standard duct flange connections simplify rooftop ductwork integration. Compact form factor maximizes space utilization on building tops where square footage is premium.
Simplified Maintenance Access
Removable service doors provide direct access to critical components. External pressure gauge ports on 7.5-15 ton models allow quick refrigerant verification. LED self-diagnostic indicators enable faster troubleshooting, while cleanable filters support routine maintenance without specialized tools.
Comprehensive Protection Systems
Multi-level protection includes current overload protection, high and low pressure cutoffs, and temperature sensor monitoring. Optional three-phase protection devices are available for facilities requiring enhanced electrical fault management, detecting issues before they escalate into major failures.
Global Parts and Service Network
Backed by Midea's global service network with certified technicians across major markets, ensuring responsive technical support and genuine replacement parts throughout the unit's operational lifespan for reduced equipment downtime.
