Product Details
Our commercial large floor-standing total heat exchangers deliver reliable, high-efficiency ventilation for large-scale commercial and public buildings such as malls, hotels, offices, and convention centers. With airflow from 5,000 to 35,000 m³/h and a maximum static pressure of 380Pa, they ensure stable air distribution in complex, multi-branch duct systems, eliminating airflow loss over long distances. A 72% heat recovery rate reduces HVAC energy use by reclaiming exhaust air energy, lowering operational costs year-round.
Powered by 380V three-phase electricity with heavy-duty dual fans, these units support continuous, high-load operation. The floor-standing design saves ceiling space, offering flexible placement in equipment rooms, while standard duct connections (338×400mm to 1520×480mm) ensure compatibility with common commercial ductwork for easy installation. Durable and low-maintenance, they are ideal for large projects needing robust, energy-efficient ventilation.

Key Technical Advantages
Strong airflow & pressure performance：With static pressure up to 380Pa, these units maintain consistent airflow through long, multi-branch ductwork, eliminating end-of-line attenuation in large buildings. Noise levels are kept between 65–70 dB(A), balancing power with workplace comfort.
Efficient energy recovery：All models feature a stable 72% heat recovery rate, capturing thermal energy from exhaust air to reduce HVAC loads and cut long-term operational costs.
Heavy-duty, continuous operation：Powered by 380V three-phase electricity with dual high-power fans (3,000W to 15,000W each), they support 24/7 high-load operation. The robust build ensures durability, with unit weights ranging from 350kg to 2,450kg.
Flexible installation：Standardized duct connections (338×400mm to 1520×480mm) are compatible with mainstream commercial ductwork, while the floor-standing design saves ceiling space and allows placement in equipment rooms or mechanical areas.
Note: Custom configurations of the units are available upon customer request.
Dual-air duct structure: The interior of the unit is divided by baffles into two independent channels for fresh air and exhaust air, enabling cross-flow of air streams to complete the heat exchange process.
Multi-interface layout: The inlet and outlet directions for fresh/exhaust air are clearly marked to prevent on-site misconnection and ensure proper airflow organization.
Convenient maintenance: An access door is reserved on the side, allowing maintenance of internal components such as filters and fans without disassembling the entire unit.
Standardized dimension marking: Dimension labels (A, B, D, H, L, R, etc.) facilitate verification of the equipment’s footprint and duct connection sizes by engineering personnel, ensuring installation compatibility.
