BE Series Commercial Total Heat Recovery Fresh Air Handling Unit

BE series large commercial bidirectional total heat exchange fresh air ventilator is heavy-duty ceiling concealed ventilation equipment for large public spaces, adopting anti-mold antibacterial nano membrane total heat core, dual-inlet fan structure, multi-stage filtration and galvanized steel cabinet. It covers airflow range from 1500 to 12000 m³/h, 380V industrial three-phase power supply, widely used in hospitals, factories, schools, shopping malls, catering halls and entertainment venues.

Core Product Features

Structural & Functional Advantages

Anti-Mold Antibacterial Nano Membrane Total Heat Core High water permeability & heat transfer efficiency, strong anti-bacterial & mildew-proof performance, recyclable and long service life; cross-flow channel design extends air contact time, enlarges heat exchange area, fixed 70% heat recovery efficiency, reduces central air conditioning power consumption by over 30%.

Dual-Inlet Fan System Double suction centrifugal fan wheel + optimized volute air duct, high static pressure for long-distance multi-branch air duct layout, low noise and energy-saving continuous operation.

Multi-Stage Filtration System Standard primary filter screen installed at air inlet, intercepts dust, particulate pollutants to keep heat core clean and extend service life.

Galvanized Sheet Split Cabinet Double-side maintenance access doors, convenient disassembly for filter cleaning and heat core replacement; rust-proof, airtight structure stable for long-term commercial all-day operation.

Large Airflow & High Static Pressure Grades 10 model specifications, max static pressure up to 850Pa, suitable for large-area complex pipeline engineering projects.

Working Principle

Simultaneous bidirectional air supply & exhaust with energy recovery:

Outdoor fresh air passes primary filter, exchanges temperature & humidity with indoor exhaust air through nano heat core, then purified fresh air is delivered to all functional zones via air ducts.

Indoor turbid exhaust air transfers residual cooling/heating energy to incoming fresh air before being discharged outdoors, realizing efficient energy recycling and constant fresh oxygen environment for large spaces.

Typical Application Scenarios

· Public medical: Hospitals, clinics, medical laboratories (anti-bacterial demand)

· Industrial: Manufacturing workshops, food processing factories

· Education: Primary & secondary schools, universities, training centers

· Commercial: Shopping malls, catering restaurants, banquet halls, hotels, entertainment venues

· Matching demand: Large closed spaces with high air change frequency, venues requiring energy-saving ventilation and high air cleanliness

Model Selection Case Reference

Take BE40 as example: Suitable for a 380㎡ restaurant with air change rate of 5 times/hour. Single BE40 unit meets full-space fresh air circulation demand, achieves over 30% energy saving on air conditioning via total heat recovery.

Usage Restrictions

· Installation: Ceiling concealed hoisting only, not for exposed floor standing installation.

· Power supply: Fixed 380V 50Hz three-phase industrial power supply, not compatible with household single-phase sockets.

· Operating ambient temperature: -10℃ ~ 45℃, avoid outdoor exposure and long-term direct sunlight.

· Maintenance cycle: Clean primary filter every 1–2 months; inspect and clean total heat core every 6–12 months according to site dust concentration.
