Blue Air Dryer This Blue Air Systems dryer module, also known as the BBX, can be used as a replacement of the drying unit in conventional dryers to convert them to dry process air. Doing so represents an energy-efficiency upgrade over commercially available drying systems, such as adsorption dryers or molecular sieve dryers. For PET processing, throughputs of up to around 2,200 pounds per hour are achievable. Higher process volumes are possible with tailor-made systems. Along with the BBX, users can specify an optional database for dryer settings and a fill level sensor. 

What’s new? The Blue Air BBX Dryer module, which premiered at the K show. 

Benefits Ease of use, minimal operating costs and potential energy savings of 50 percent to 70 percent, compared with conventional hot-air pellet dryers. Pellets treated this way can be used in injection molding and blow molding. Unlike conventional drying strategies, a Blue Air Dryer requires no regeneration energy. It enables a constant dew point without any fluctuations, but does not require cooling water or a molecular sieve during operation. It requires an air filter change only after a long period of use. Also, the BBX is compact and can be set up easily, using the existing hopper. Thanks to intelligent digital pneumatics, only the exact amount of process air required to complete the drying task is used.
