Furnaces & Technologies Nitriding / Nitrocarburizing P-Series

The P-SERIES is part of the NITREX portfolio of nitriding/nitrocarburizing systems and is designed primarily for commercial heat-treating companies.

P-SERIES takes advantage of the best-in-class Nitrex nitriding/nitrocarburizing furnaces and features flexible controls based on UPC-Marathon PROTHERM™ controllers, which are capable of running the most advanced user-configured recipes with % Diss, KN, KC, and KO setpoints to meet AMS 2759/10 and 2759/12* standards. PROTHERM™ controllers are feature-rich and offer easy connectivity to the PROTHERM™ 9800 Production Management Software or to third-party SCADA systems. The integrated recipe builder allows users to design recipes by configuring process parameters such as % Diss, KN, KC, KO, temperature, atmosphere mixtures, furnace pressure, and more.

The P-Series opens new avenues for expert users looking to leverage and support their in-house recipe development and process design capabilities.

FURNACE TYPES

The P-Series is available in three different batch furnace types – NXKP, NXHP, and NXP.

The multipurpose NXKP series is a compact and economical choice for use in small-scale processing as well as process development. The heavy-duty NXHP and NXP series provide flexibility for a wide range of applications from small to high volume batch processing.

Furnaces are designed to have fast heating and cooling rates, as well as uniform temperature and atmosphere throughout the work zone. By incorporating multiple controlled heating zones, temperature uniformity inside the retort is +/-5 °C (9 °F) or better.
