Comfort Heat Pump System with IdealHumidityt featuring Infinityt control variable-speed blower motor and two-stage cooling and heating that provides greater comfort, humidity control, and energy efficiency.

Variable-speed blower motors provide better comfort and energy efficiency. You can expect up to 30 times better dehumidification; economical constant airflow which provides improved indoor air quality and more even temperatures from room to room; and reduced indoor noise due to lower air velocity. In addition, you’ll realize improved installation flexibility with 3 different airflow choices for best overall comfort.

Easy installation

Factory-assembled package is a compact, fully self-contained heat pump unit that is pre-wired, pre-piped, and pre-charged for minimum installation expense. 50XT units are available in a variety of standard capacity ranges. Units install easily on a rooftop or at ground level.

Durable, dependable components

Compressors have two stages of cooling and heating and are designed for high efficiency. Each compressor is hermetically sealed against contamination to help promote longer life and dependable operation. Vibration isolation provides quiet operation. Compressors have internal high-pressure and overcurrent protection.

Convertible duct configuration

Unit is designed for easy use in either downflow or horizontal applications. Each unit is easily converted from horizontal to downflow with two duct covers (available as an accessory). Downflow operation is easily provided in the field to allow vertical ductwork connections. The basepan utilizes knockout style seals on the bottom openings to ensure a positive seal in the horizontal airflow mode.

Direct-drive, variable-speed blower motor is standard on all 50XT models.

Direct-drive, PSC condenser fan motors are designed to help reduce energy consumption and provide for cooling operation down to 55°F (12.7°C) outdoor temperature. Low-ambient cooling is available below 55°F (12.7°C) when low-ambient cooling is enabled in the User Interace (UI). Motormaster→ II low-ambient kit is not required.

Infinityt User Interface is designed to work as a system with Carrier’s single-packaged product.

Refrigerant system is designed to provide dependability. Liquid refrigerant filter driers are used to promote clean, unrestricted operation. Each unit leaves the factory with a full Puron refrigerant charge. Refrigerant service connections make checking operating pressures easier.

Indoor and outdoor coils are computer designed for optimum heat transfer and cooling efficiency. The indoor coil is fabricated from copper tube and aluminum fins and is located inside the unit
