    Save Energy and Money

    Large amounts of energy and thus your money can be saved by recycling your hot air. LEISTER has customized solutions for combining air heaters and blowers that are suitable for recycling hot air, thanks to an integrated design Leister made to withstand high temperatures.

    In order to heat a defined volume of air (air volume) to the desired temperature, a certain amount of energy needs to be expended. The greater the difference in temperatures (ΔT) between the air inlet (ambient) and the air outlet (heated), the more energy that is needed. This ΔT is reduced by operating your process configuration with recirculating hot air. That Saves Energy and Associated Costs.

    To ‘recycle’ the hot air in your process, both the blower and the air heater need to be able to withstand the high temperatures at the air inlet side of the setup. LEISTER’s double-flange air heater types LE 5000 DF R and LE 10000 DF-R along with the RBR blower provide the solution. Air with a temperature of up to 350°C can be moved, reheated and recirculated without a problem.

    When accessories such as insulated hoses, high-temperature seals and various flanges are added, systems with air heaters and blowers become perfectly supplemented for recycling applications.
