The Carrier 39HX is a versatile dual-flow air handling unit engineered for high-efficiency ventilation across a variety of commercial and communal environments. Designed as a complete Plug & Play solution with built-in controls, the system integrates advanced plug fans and high-performance EC motors to meet stringent modern ecodesign standards. Available in multiple configurations, including HXE, HXA, HXC, and HXV models, the unit offers air flow capabilities ranging from 300 to 18,000 m³/h, making it suitable for offices, educational facilities, healthcare centers, and retail spaces. The construction features durable double-skin panels with 50 mm mineral wool insulation to ensure robust performance and thermal efficiency. Energy recovery is a core strength of the 39HX series, utilizing high-efficiency heat exchangers—including "Contra Flow" plate designs and rotary options—to achieve efficiency levels exceeding 80%. The system supports comprehensive filtration options and offers advanced control functionalities, such as variable speed management, free cooling, and night cooling modes. With extensive accessory support, including CO2 sensors, hydraulic coils, and various communication protocols like ModBus, LON, and Bacnet, the 39HX provides facility managers with precise control over indoor air quality and energy consumption.
