OLEG SYSTEMS

Flue gas recirculation is a highly effective technique used for lowering Nitrogen Oxide (NOx) emissions from burners. This is particularly crucial, as NOx is a significant pervasive pollutant that produces a negative array of health and environmental by-products. NOx emission levels can be greatly reduced in industrial boilers by reticulating used flue gases back into the system. This process lowers the peak combustion temperature and drops the percentage of oxygen in the combustion air/flue gas mixture, delaying the formation of NOx caused by high flame temperatures. TCF offers a wide range of centrifugal blowers specifically designed to be used with FGR systems. Forced Draft fans purpose is to provide a positive pressure to a system. This basic concept is used in a wide variety of industries but the term FD Fans is most often found in the boiler industry. Fans for boilers force ambient air into the boiler, typically through a preheater to increase overall boiler efficiency. Inlet or outlet dampers are used to control and maintain the system pressure. Typical fan arrangements are 3SI or 3DI which utilize a wheel center hung on the shaft with integral inlet boxes. Air Handling Units (AHU) combine a fan (or several fans) with other components such as heating and/or cooling elements, filters, and dampers as a means to collectively condition the air in a building. AHU is a general term comprised of many specific types of air handlers including: Make-Up Air Units (MAU), Packaged Units (PU), Rooftop Units (RTU), and Energy Recovery Units (ERU). Air handlers range from very small, low CFM light-duty construction to very large, high CFM heavy-duty construction, and are used in many types of buildings that require air conditioning such as office buildings, hospitals, universities, schools, manufacturing facilities, and data centers. Typically, air passing through an AHU is clean and varies in temperature depending on the specific application. Energy consumption and noise are often important considerations when selecting a fan for an AHU. Plenum fans and DWDI fans are commonly found in these units, but are not used exclusively. To accommodate the various applications these units are used for, Buffalo Blower offers the most diverse and efficient fans in the industry to meet the need of any air handling unit. CBRE Roof Recirculators function as regular power roof ventilators in warmer weather and as an energy-saving recirculation air system in cold weather.  Each unit is equipped with a reversible fan that distributes warm ceiling air thoughout the plant and reduces the builing's heating requirements. With a flip of a switch it can function as a conventional roof ventilator. There are two unit types: 1) for exhaust and recirculation; 2) for exhaust, supply and recirculation.
