HD4T Series Industrial Oven by PQ Ovens


The Precision Quincy HD4T Oven model line provides customers with the ultimate in oven performance in a small footprint package. Designed for customers who place a high value on 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. The HD4B oven line comes with Horizontal-Vertical Airflow standard, but can also be configured in the shelf cart friendly Full Horizontal Airflow Configuration.

These ovens are well suited to handle most industrial heat processes requiring a 500f maximum operating temperature. Applications include annealing, curing, powder coating, composites curing, dehydrating, hydrogen de-embrittlement, drying, heat setting, heat shrinking, pre-heating, stress-relieving, testing, and many more.
