Heat Pump Units with Puron® (R-410A) Refrigerant
6 to 20 Nominal Tons
WeatherMaker® 50TCQ rooftop units were designed to be easy to install, maintain, and operate, with customer-requested features including a gage port, centralized control center, plug-and-play accessory board, "no-strip screw" collars, and hinged access panels. Units are field-convertible to horizontal airflow without special adapter curbs or kits, making it easy for the installer to adjust to unexpected jobsite complications. Units are pre-wired and pre-charged with environmentally sound Puron (R-410A) refrigerant and are factory tested.
