QBP Blower Purge Desiccant Dryer


QBP Blower Purge Desiccant Dryer


Quincy QBP dryers combine heat with forced ambient air for regeneration. As a result, they have a lower purge requirement than both the QHD and QHP desiccant dryer systems. The QBP is available in 13 different configurations that can produce between 210 and 3,400 CFM of dry air at 100 psig.

While they are more expensive to purchase outright than other models, a QBP dryer’s lower ownership and maintenance costs deliver a strong ROI over the life of the product.

After air has passed through the drying tower, a small amount is heated and blown down through the purge tower, where moisture is removed from the desiccant. The blower component improves the overall efficiency of this process, requiring less air to perform the same amount of work. Sophisticated electronic controls and regulators automate the cycle, making it worry- and maintenance-free. Average purge levels are kept to 1.75%.
