WeatherExpert® Light Commercial Packaged High Outdoor Air System
50LCH

Cooling Only or Electric Cooling/Heating Units with Puron® (R-410A) Refrigerant

6 to 10 Nominal Tons

The WeatherExpert® packaged high outdoor air system is a special configuration of WeatherExpert packaged rooftop unit that can operate with up to 100% outdoor air for ventilation or make-up air in light commercial applications. The WeatherExpert 50LCH includes new options that enable 100% outdoor air operation, including modulating low load protection valve to prevent refrigerant circuit issues at low loads, modulating hot gas reheat for dehumidification with supply air temperature control, modulating electric heat for a wide heating operating range, and the exclusive EcoBlue ™ vane axial supply fan a wide airflow range. All units include Carrier SmartVu™ controls for control flexibility, ease of setup and commissioning, and simplified troubleshooting.
