Our Range of high performance industrial furnaces

    Our Integral Sealed Quench Furnaces incorporate a cast integral fan to ensure uniformity of temperature. These furnaces provide the option of using Endothermic gas, Nitrogen-Methanol or Fine Carburising Process.
    Our THN furnace provides a completely shielded environment for the work piece backed by a fully automatic operation. Parts are treated at a temperature lower than the A-1 transformation point in a mixed gas atmosphere consisting of ammonia and endothermic gas.
    Offer consistent production at low operating cost and includes data acquisition systems. Available in various capacities ranging from 50 to 400 kgs per hour.
AFC-Holcroft designed (Controlled Atmosphere Aluminum Brazing) CAAB® provides the most advanced and state-of-the-art technological edge for processing aluminum heat exchangers such as radiators, heater cores, condensers, evaporators, charge air and oil coolers.
Our Mesh Belt Continuous Conveyor furnace systems are specifically designed to cater to a wide range of heat treatment applications, with 1600 kgs per hour processing and a tension free belt drive design. They are available for both atmospheric and non atmospheric processes such as Hardening, Carburising, Carbonitriding, Washing, Annealing, Tempering, Isothermal Annealing and Stress Relieving.
Our Decarb Annealing & Blueing furnace is the outcome of a special design based on advanced Japanese technology for the conversion of non Silicon steel as lamination for motor stators and rotors.
Our Endothermic Gas Generators feature a unique soot-free control system with an excellent reputation for trouble-free operation. Endothermic Gas Generator creates an atmosphere to provide a positive pressure in a heat treating furnace and a platform to formulate the carburizing environment.
