The better PKR. With internal atmosphere circulation for precise temperature distribution
For this furnace, the same applies as for PKR—a precisely defined protective atmosphere protecting the surface of the charge from unwanted changes, relatively low gas consumption, a variant with argon, nitrogen, or forming gas, and so on. However, the PKRC furnaces also have even better temperature distribution than PKR furnaces thanks to internal atmosphere circulation.
For the PKRC furnaces, you can also pay extra for a retort made from of type Inconel material that can handle a temperature 150 °C higher than a stainless steel retort can. We can also adapt PKRC furnaces to nitriding furnaces at your request.
