GRAD High-Efficiency Fan Coil Unit (FCU) – Patented HVAC Terminal for Central Air Conditioning
The GRAD Fan Coil Unit (FCU) is a high-performance terminal unit for central air conditioning systems, consisting primarily of a centrifugal fan and a high-efficiency heat exchanger. Engineered for versatility, it is the ideal cooling and heating solution for large-scale civil and industrial buildings, including hotels, restaurants, factories, exhibition halls, shopping malls, and office complexes.
Advanced Technical Features
Superior Heat Exchange Performance: The surface cooler utilizes high-quality purple copper tubes and high-efficiency hydrophilic aluminum foil fins. Integrated mechanical expansion ensures a seamless bond between tubes and fins, maximizing the heat exchange area.
Leading Energy Efficiency: With a multiple reverse flow design, our units exceed national energy efficiency standards by more than 15%. Our "High-Efficiency Type" models can even outperform standard parameters by over 20%.
Ultra-Quiet Operation: Equipped with an optimized large fan wheel running at low speeds and high-efficiency sound-absorbing insulation, the noise level is 1-2dB lower than national standards.
High Airflow Capacity: Offers a wide range of air volume options, reaching a maximum supply air volume of 3400m³/h.
Durable & Safe: The tower body features a frame formed by one-time bending of hot-dip galvanized steel with C-shaped groove reinforcement. It supports a maximum working pressure of 1.6 MPa.
