High-Output Under Ceiling Heat Pump for Large Commercial Environments
The Samsung Under Ceiling Heat Pump 13.4kW three-phase system is engineered for large commercial spaces where powerful airflow, long throw and reliable performance are essential. Designed for buildings without suspended ceilings, the unit is mounted directly beneath the ceiling, delivering strong horizontal air distribution across wide, open areas.
As part of Samsung’s Big Ceiling Inverter range, the system features an enlarged discharge blade and enhanced fan assembly capable of projecting air over distances of up to 15 metres — delivering significantly greater coverage than conventional ceiling units. This makes it particularly well suited to high-ceiling environments such as warehouses, gyms, retail floors, exhibition spaces, halls and large commercial interiors.
Digital Inverter technology continuously adjusts compressor output to match real-time demand, improving energy efficiency while maintaining stable indoor temperatures. The supplied wired controller allows full control of fan speed, airflow direction and operating modes, with the option to restrict user access to prevent unauthorised changes and support effective energy management. Using R32 refrigerant, the system delivers efficient year-round heating and cooling with reduced environmental impact.
