Heat treatment




Libratherm has been supplying various temperature controllers and systems for this industry. Our model PRC-300, PRC-309 is in use for annealing, hardening and tampering cycles. Our model PRC-301 is specially designed for carburizing and nitriding heat treatment cycles. We have developed some special models for this application. Our model PRC-8000 is widely used for the pre and post welding heat treatment applications – where the large jobs are welded and locally heat treated with six to eight thermocouples welded along the length of the welding joints. The desired ramp/soak cycle with auto hold and synchronization of all six to eight zone is achieved using this model.
