Product Description

The MRCT Series Cooling Only Rooftop Package Unit is purpose-engineered for commercial and industrial applications where dedicated air conditioning is the primary requirement. This focused approach to cooling-only design eliminates the complexity and cost associated with integrated heating systems, making it an economically smart choice for facilities where heating is handled by separate equipment or is simply unnecessary.

The system offers an impressive capacity range from 6.2 to 30 tons, providing scalable solutions for facilities of various sizes. At its core, the MRCT Series employs the same premium scroll compressors from Copeland, Hitachi, and Danfoss that power our heat pump models. These compressors feature advanced scroll technology with asymmetric profile designs that minimize internal leakage and maximize volumetric efficiency, ensuring consistent, reliable cooling performance year after year.

What distinguishes the MRCT Series is its exceptional cooling capability in high-temperature environments. While many rooftop units struggle when ambient temperatures exceed 45°C, the MRCT maintains reliable operation up to 52°C. This makes the series particularly well-suited for data centers, manufacturing facilities, commercial kitchens, and buildings in hot climate regions where heat rejection challenges are most acute.

Durability is engineered into every aspect of the unit's construction. The G90 galvanized steel cabinet provides a robust barrier against environmental factors, with 500-hour salt spray testing confirming corrosion resistance suitable for coastal and industrial installations. The vertical discharge configuration simplifies integration with existing infrastructure while the thoughtfully designed service access points facilitate efficient maintenance procedures.

With EER ratings ranging from 9.1 to 11.4 Btu/h.W, the MRCT Series delivers energy-efficient cooling that translates to lower operational costs. The cooling-only design means no energy is wasted on unnecessary heating functions, resulting in optimized efficiency for applications that require cooling exclusively. This targeted approach provides building owners with a cost-effective solution that delivers exactly what their facilities need.

Features & Benefits

Purpose-Built Cooling Architecture — By focusing exclusively on cooling, the MRCT Series achieves superior optimization for refrigeration applications. Without the complexity of heating components, the system allocates all available capacity to cooling, resulting in higher cooling output per unit of energy consumed. This design philosophy provides exceptional value for facilities where heating is handled by separate systems or where climate conditions make heating unnecessary.

High-Temperature Environment Performance — The MRCT Series is engineered to deliver reliable cooling up to 52°C ambient temperature, a capability that sets it apart from conventional rooftop units. This extended range is achieved through advanced refrigeration circuit design, optimized refrigerant charge, and high-efficiency fan motors that maintain adequate airflow even under extreme heat conditions. Facilities in tropical regions, commercial kitchens, and industrial environments benefit from dependable cooling regardless of outside temperatures.

Premium Compressor Technology — The same industry-leading scroll compressors from Copeland, Hitachi, and Danfoss that power our heat pump models are featured in the MRCT Series. These compressors are designed for continuous duty operation with exceptional reliability ratings. The scroll compression mechanism inherently reduces moving parts compared to reciprocating compressors, resulting in fewer failure points, reduced maintenance requirements, and extended operational lifespan.

Outdoor-Durable Construction — Constructed with G90 galvanized steel that has been tested to withstand 500 hours of salt spray exposure, the MRCT cabinet delivers long-term durability in demanding outdoor installations. The cabinet features a multi-stage surface preparation and painting process that creates an effective barrier against moisture, UV radiation, and atmospheric pollutants. Optional enhanced anti-corrosion coatings are available for the most challenging coastal and industrial environments.

Versatile Installation Options — The vertical side-discharge configuration eliminates the need for complex ductwork modifications, enabling flexible placement on rooftops or ground-level pads. This design is particularly advantageous for retrofit applications where existing duct configurations may not accommodate traditional rooftop unit airflow patterns. The standardized mounting footprint facilitates straightforward replacement of aging equipment while minimizing installation disruption.

Energy Efficiency Optimization — With EER ratings spanning 9.1 to 11.4 Btu/h.W, the MRCT Series offers excellent energy efficiency for cooling-only applications. The dedicated cooling design ensures no energy is diverted to unnecessary heating functions. Advanced controls optimize compressor cycling to match building loads precisely, reducing energy waste during partial load conditions that occur frequently in commercial buildings.

Comprehensive Protection Suite — Built-in protection systems safeguard equipment against abnormal operating conditions including high and low refrigerant pressure, electrical overcurrent, and temperature sensor faults. These protective measures prevent damage from improper operating conditions, extend equipment life, and minimize costly emergency repairs. The unit's control system continuously monitors performance parameters to ensure safe, reliable operation.

Smart Control Integration — The MRCT Series supports integration with building management systems through standard communication protocols. This enables remote monitoring of operational status, alarm notifications, and adjustment of setpoints from a central control station. Building operators benefit from improved operational oversight while maintenance personnel can identify and address issues before they result in equipment failures.
