The New Carrier WeatherMaker® packaged heat pump rooftop units (RTU) with EcoBlue™ Technology were designed by customers for customers and integrate new technology to provide value added benefits never seen in this type of equipment before.
New major design features include:
- Patent, industry’s first efficient indoor fan system using Vane Axial fan with electric commutated variable speed motor
- Reliable fixed speed scroll compressor on 3-5 ton sizes and 2 stage scroll technology on 6 ton sizes
- Upgraded unit control board with intuitive indoor fan adjustment
- Reliable copper tube/aluminum fin condenser coil with 5/16-in. tubing to help reduce refrigerant charge versus prior designs
- New outdoor fan system with rugged - lightweight high impact composite fan blade
Single-stage units deliver SEERs up to 14.3. IEERs up to 15.0 and heating HSPFs up to 8.2. All models are capable of either vertical or horizontal airflow.
The Carrier rooftop unit (RTU) was designed by customers for customers. With “no-strip” screw collars, handled access panels, and more, the unit is easy to install, easy to maintain, and easy to use. Precisely sized Suction Line Accumulator to help insure reliable operation at unit operation conditions.
Value-added features include:
- Puron® refrigerant (R-410A)
- Single point electrical connections
- Optional fully integrated SystemVu™ controls
- RTU Open controller for BACnet1, LonWorks2, Modbus3 and Johnson Controls N2
- 3 to 5 ton models use fixed refrigerant metering devices and 6 ton models use a TXV
- Scroll compressors with internal line-break overload protection
- Easy access tool-less filter door. Filter track tilts out for filter removal and replacement. All filters are the same size in each unit
All WeatherMaker units are fieldconvertible to horizontal airflow, whichmakes it easy to adjust to unexpected job-site complications. Lighter units make for easy replace. Simple, fast plug-in connections to the standard integrated unit control board (UCB). Clearly labeled connections points to reduce installation time. Also, a large control box provides room to work and room to mount Carrier accessory controls.
Easy to maintain
With the new EcoBlue Vane Axial fan system and direct drive ECM motor, there is no longer a need to adjust belts or pulleys as in past designs. This frees up maintenance and installation time. Easy access handles by Carrier provide quick and easy access to all normally serviced components. Our “no-strip” screw system has superior holding power and guides screws into position while preventing the screw from strip- ping the unit’s metal. Sloped, corrosion resistant composite drain pan sheds water; and won’t rust.
Easy to use
The newly re-designed Unit Control Board by Carrier puts all connections and troubleshooting points in one con- venient place. Most low voltage con- nections are made to the same board and make it easy to access it. Setting up the fan is simple by an intuitive switch and rotary dial arrangement. Carrier rooftops have high and low pressure switches, a filter drier, and 2-in. filters standard.
Direct drive EcoBlue Technology indoor fan system uses Vane Axial fan design and direct drive electrically commutated motors. This new Vane Axial design over past belt drive systems has 75% fewer mov- ing parts, uses up to 40% less energy and has no fan belts, blower bearings and shaft.
Streamlined control and integration
Carrier controllers make connecting WeatherMaker® rooftops into existing building automation systems easy. The units are compatible with conventional thermostat controls, SystemVu™ controls and Carrier RTU Open multiprotocol controller.
Operating efficiency and flexibility
The 50FCQ rooftops meet ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) 90.1-2016, IECC1-2018 (International Energy Conservation Code) minimum efficiency requirements.
Field convertible airflow
All WeatherMaker 3 to 6 ton units are field-convertible to horizontal airflow, which makes it easy to adjust to unexpected job-site.
Carrier’s Round Tube Plate Fin coil design helps maximize heat transfer and reliable operation.
