50FF

Compact, high‑efficiency packaged rooftop unit delivering reliable cooling and energy‑optimized performance for medium and large commercial spaces
The Carrier 50FF Packaged Rooftop Unit is a cooling‑only, air‑to‑air rooftop solution designed for commercial and industrial applications. With advanced compressor technology, EC fan systems, and intelligent microprocessor control, the 50FF offers high seasonal efficiency, easy installation, and dependable long‑term operation.

Features

General description

Optimized part-load management High level of seasonal efficiency Self-supporting frame Multi-scroll compressors Electronic expansion valves Variable speed EC fans Auto-adaptative microprocessor control

Design flexibility

Vertical supply/return units are ideal for new construction or retrofit to existing installations Horizontal units are ideal for replacement or applications such as through-the-wall where sound must be attenuated before the duct penetrates the roof

Easy and fast installation

Connected directly to an air distribution ductwork without additional elements or equipment, pipes, cables, etc. taking no floor space at all Reduces the cost of installation, facilitates a quick connection and ensures reliable operation

Superior reliability

Excellent full and part load efficiencies are achieved by using tandem scroll compressors Compressors are equipped with crankcase heaters and protected by electronic sensors and logic to control minimum on and off times and reverse rotation All units are tested at various stages on the production line for circuit leakage, electrical compliance and refrigerant pressures

Advanced technology and performance

Electronic plug-fans in the indoor circuit with direct drive and variable speed offer the following advantages: Elimination of friction losses during transmission thanks to the direct drive Greater aerodynamic efficiency of the rotor (reactive blades with an optimized profile), running at very high operating pressures Greatly increased motor efficiency. Permanent magnets DC motors activated using electronic switching integrated into the motor itself Variable speed to ensure a constant supply air flow rate, independent of the filters clogging level Measuring the flow rate Electronic axial fans in the outdoor circuit which adapt the rotation speed to the installation’s requirements, reducing electricity consumption, the sound level at part load and improving the unit’s average seasonal efficiency

Environmental care

Making an environmentally responsive decision is possible when using R-410A refrigerant No wooden pallets needed for handling, thus eliminating not only the waste disposal but avoiding the cut of trees
