P-SERIES NITRIDING / NITROCARBURIZING SYSTEMS

P-SERIES Nitriding / Nitrocarburizing System with United Process Controls’ PROTHERM™ Process Controller

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

It takes advantage of the best-of-class Nitrex nitriding / nitrocarburizing furnaces and features flexible controls based on United Process Controls’ 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* specifications. 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 the user to design a recipe by configuring process parameters such as % Diss, KN, KC, KO, temperature, atmosphere mixtures, furnace pressure and more.

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

NXHP series system with horizontal batch furnace



P-SERIES AT A GLANCE

FURNACE

Horizontal and vertical standard models with a load capacity of up to 1500 kg (3330 lb) and 10,000 kg (22,000 lb) respectively for a broad range of applications. Furnaces are designed to have fast heat-up 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.

PROCESS CONTROLS

The PROTHERM™ controller monitors and regulates all furnace functions, nitriding / nitrocarburizing cycles with % Diss, KN, KC, KO setpoints, alarms, and maintenance tasks. The integral H2Smart™ sampling system ensures extremely accurate measurement of hydrogen in the process atmosphere, thereby achieving precise control of processes.
