    75KVA Heat Treatment Equipment

    75KVA Heat Treatment Equipment

    PART NO: LVHT75K

    The LVHT75K 75KVA Heat Treatment Equipment is a state-of-the-art solution for Post Weld Heat Treatment (PWHT) operations. It utilizes the traditional low-voltage electrical resistance method with Ceramic Pad Heaters and Ceramic Blankets, controlled by step-down transformers. This system provides an efficient and convenient approach to many industrial jobs, particularly preheating and PWHT, ensuring optimal results in stress relief, microstructure improvement, and weld integrity.

    The unit features six individual output channels, each capable of delivering 12.1 kW of power, which is sufficient to operate four standard ceramic pads rated at 2.7 kW. This heat treatment system is mobile and can be used on-site or in a fabrication shop. It is designed to be flexible, with multiple control options, including fully-integrated individual programmers, external programmers, and individual proportional energy regulators.

    With robust features and easy-to-use controls, the LVHT75K is the ideal solution for ensuring structural integrity and reducing risks associated with welding processes, such as stress cracking and fatigue.
