INSPIRED INNOVATION
u PN Series Inert Atmosphere Ovens
Ideal for Wide Variety of Inert Atmosphere Applications
e 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.
e PN Series contains a digital PID controller that is easy to use and congure saving the operator time. It comes with two temperature ranges and two sizes to meet your process needs. e 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 “ne tuning” to assure uniform airow, even with varying load congurations and consistent product heating. It also has a heat exchanger for providing rapid cool-down or the ability to operate at low temperatures within a sealed chamber – Air-to-water is used on 343°C models, air-to-air for 538°C models.
Despatch provides the design integrity, manufacturing experience and emphasis on quality necessary for dependable operation and excellent process control.
