Prodotti Destratificatori AEB




Reznor's AEB indirect fired units are designed for indoor or outdoor installation in industrial and commercial buildings where air turnover (destratification) is desired. By capturing and recirculating the hot air trapped at the ceiling level, and then forcing it back into the work area, additional energy use can be avoided, dramatically reducing both installed cost and operating cost.Model AEB units offer a complete range of sizes for air handling capacities from 3,250 to 150,000 CFM and heating outputs from 200,000 to 6,000,000 BTUH.

In addition to natural gas, LP and fuel oil, Model AEB can be fitted for steam, hot water or electric coils for heating. For outdoor units an interior trapezoidal shaped discharge section can be provided to distribute air inside the building.

Air turnover units are ideal for large open space heating, cooling, ventilation and filtration requirements. Air turnover units are also very effective at controlling humidity levels in a space.

Application Examples:

  • Manufacturing, distribution, warehouse facilities, steel, pharmaceutical, food and merchandise storage facilities. 

Exterior Details:

  • Constructed of a welded structural iron frame, primed with an epoxy rust inhibitor
  • Cabinet is constructed of G90, 18 gauge metal
  • An industrial alkyd enamel gray finish is applied
  • For outdoor units, epoxy finishes or custom coloring can be selected to match a building exterior
  • Hinged access doors with stainless steel piano hinges, compression latches and safety switches make easy fan and motor access


  • Uniform space temperatures
    • Uniform space temperatures provide more comfort and reduced building stratification. Heat loss and fuel consumption are reduced to a minimum with even space temperatures.
  • Reduced operating costs
    • The highly efficient propeller fan provides the lowest electrical consumption to distribute air throughout a building. Outside air is not required for operation, the air turnover unit can recirculate up to 100% space air.
  • Lower installation costs
    • Base mounted air turnover units relatively simple to stack and wire. The units do not have to be hung or supported and do not require ductwork to be cut through the roof.
  • Rapid temperature recovery
    • Air turnover units constantly circulate large volumes of air providing rapid response to temperatures deviating from a set-point.
  • Outstanding indoor air quality (IAQ)
    • Air is constantly rotated throughout the building to prevent stagnation.
