NITREX METAL

Nitriding 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.

Features & Benefits

FURNACES

• Inconel 600 (refractory steel) retort and racking for long service life and non-reactive interaction with nitriding atmosphere
• Uniform temperature distribution obtained through independently controlled heating zones and intensive atmosphere circulation ensuring full control of nitriding potential throughout all stages of the process
• Light ceramic fiber insulation reduces heat loss and thus energy consumption
• Kanthal long-lasting heating elements
• Efficient internal recirculation ensures uniform process atmosphere
• Heating system provides exceptional temperature uniformity throughout the workload
• Larger furnaces may be equipped with a ‘Turbo’ cooler for accelerated load cooling. This option is used where productivity is a major issue
• Preconfigured and factory-tested
• Fully automated operation guarantees repeatable and consistent results
• System for data archiving and reporting as well as remote diagnostics
• SCADA connectivity
• Clean, environmentally-friendly processes powered by Nitrex effluent neutralizers
• Some pit furnaces may be equipped with a vacuum purging system. This option significantly accelerates exchange of atmosphere in the retort and is very useful in nitriding stainless steels.

PROCESS CONTROL

• PID control loops to regulate configured process parameters such as temperature, furnace pressure, flows and atmosphere parameters (KN, KC, KO, etc.)
• Real-time control of all process stages
• Process parameters configured with alarm limits
• Notification and processing alarms
• Chart recorder to provide continuous recording of process variables
• Recipe library to create and save up to 999 recipes
• Built-in user and group security with multiple access levels
