Cooling-Only RTU for Extreme Heat 6.2-30 Ton 52°C Rated
When the climate never relents, the cooling system must never compromise. Engineered specifically for tropical megacities, desert commercial corridors, and equatorial industrial zones where cooling demand is permanent and intense.
Product Overview
The Midea MRCT Cooling Only Rooftop Unit delivers validated performance up to 52°C outdoor ambient - a thermal threshold that separates purpose-built cooling equipment from adapted alternatives. Covering 22 to 98 kW of cooling capacity (6.2-30 Ton), this series provides design teams with a focused solution where cooling reliability under extreme thermal stress is paramount.
Sharing architectural DNA with its heat pump counterpart, the MRCT features vertical side-discharge configuration, compact footprint, and G90 galvanized steel cabinet validated through 500 hours of neutral salt spray testing. The Copeland scroll compressor delivers EER ratings up to 11.3 Btu/h per W, ensuring controlled energy consumption even in sustained extreme-heat operation.
Key Features
Extreme-High-Temperature Operating Validation
Validated continuous cooling operation at 52°C outdoor ambient through rigorous performance testing
Operating range from 10°C to 52°C covers full spectrum of tropical and subtropical requirements
Engineering margin above standard design-day parameters ensures capacity during unprecedented heat events
Copeland scroll compressor maintains stable operation under high condensing pressure conditions
Focused Cooling Architecture
Cooling-only configuration eliminates weight, cost, and maintenance of unused heating components
Simplified control logic improves system reliability and reduces diagnostic complexity
Lower unit weight reduces rooftop structural load requirements
Capital budget concentrated entirely on cooling performance optimization
Tropical Climate Durability
G90 galvanized steel cabinet with 275 g/m² coating mass for certified corrosion resistance
500-hour neutral salt spray test validation per ASTM protocols
Heat exchanger fin anti-corrosion treatment improves acid rain and salt spray resistance 5-6x
Double-sided moisture-proof lacquer on all PCB boards prevents humidity-induced failures
Compact Footprint Design
Vertical side-discharge minimizes horizontal equipment envelope for dense urban rooftops
Factory-installed inlet and outlet flanges eliminate field-fabricated transition fittings
Compact base dimensions allow efficient linear or clustered configurations
Ground-level pad installation option when rooftop area is fully allocated
