50UA/UH units are packaged roof top cooling units/feversible heat pumps, available with additional heating opsitons. (hot water coil or electric heaters)
48UA/UH units are packaged roof top cooling units/reversible heat pumps, factory fitted with a multi-stage gas heater.
ADAPTABILITY - The all-in-one solution for every need
Since 2004, Carrier’s 48UA/UH & 50UA/UH rooftop range has been installed in thousands of locations worldwide. All units are factorytested before shipment in many control stations to ensure the highest level of quality.
The rooftop units may be configured to precisely match the building requirements through the use of factory and field-installed options/accessories such as: integrated economizer, power exhaust, variable-air-volume (VAV), high efficiency filters and auxillary heating options.
The rooftop units can be provided with dedicated vertical or horizontal supply/ return configurations to allow easy use on refurbishment or new construction applications. Carrier rooftop units excel in this area by providing single-point electrical connections (making electrical service access available) and large-sized hinged access panels
PERFORMANCE - More precision, more energy savings
The Touch Pilot™ control algorithm sets new standards for rooftops: precise resource control, speed of response, interactive and self-explanatory user interface together with web-server capability.
Wheel-type heat recovery reclaims up to 88% of the heat from the extracted air and transfers it to the supply air, considerably reducing the thermal load on the heating and air conditioning equipment. High-efficiency plug fan with frequency drive adjusts the fan speed to minimize power consumption when outside conditions permit.
Carrier rooftops deliver on the energy savings and reduced carbon footprint required by the latest European regulations. The VAV supply fan option allows a large fan-absorbed power reduction, improving unit part load efficiencies up to 30% in cooling and heating modes compared to the constant-air-volume fan (CAV). It offers Seasonal Energy Efficiency Ratio (SEER) in cooling of up to 3.58, making them the best value air conditioning solution in commercial and industrial applications.
