PNF Inert Atmosphere Furnace

The PN Series Inert Atmosphere Ovens are designed to accommodate a wide variety of processes where an inert atmosphere is required to prevent product oxidation. Typical applications include curing, bonding and heat treating.

The PN Series contains a digital PID controller that is easy to use and configure, saving the operator time. It comes with two temperature ranges and two sizes to meet your process needs. The stainless steel, continuously welded interior is ideal for highly corrosive conditions, or where interior cleanliness is critical. It has adjustable recirculating air louvers that allow “fine tuning” to ensure uniform airflow, even with varying load configurations, and consistent product heating. It also has an air-to-air heat exchanger for operation at low temperatures within a sealed chamber and for rapid cool down.

Despatch provides the design integrity, manufacturing experience and emphasis on quality necessary for dependable operation and excellent process control.
