PQ Ovens’ line of Draw Batch Furnaces (DBF) have a small footprint but still provide the best industrial oven performance to our clients.

Blue Draw Batch Furnace PQ Ovens


Designed for customers who value floor space, this model line’s high performance is derived from its high airflow rate and standard top return duct. These combine to produce an oven with exceptional uniformity and high energy transfer rates saving the customer valuable time and money. Featuring TrueCan™ high temp construction along with its quick change out hearth design the DBF is a reliable and flexible workhorse. The DBF furnace line comes with vertical up airflow standard.

These ovens are well suited to handle most industrial heat processes requiring a 1250f maximum operating temperature. Applications include annealing, heat-treating, pre-heating, stress-relieving, solution heat treating, and many more.
