Profile: Dowa Thermotech Co. Ltd. designs and manufactures reliable heat treatment technology and systems. Batch type integral sealed quench furnaces provide the benefit of uniform heating from the sides through radiant tube heaters located on either side. Integral sealed quench furnace incorporate a cast integral fan to ensure uniformity of temperature. For the furnace atmosphere, these furnaces provide the option of using endothermic gas, nitrogen-methanol or fine carburizing process. Mesh belt continuous conveyor furnace systems are specifically designed to cater a wide range of heat treat applications including both atmospheric and non atmospheric types such as hardening, carburising, carbonitriding, washing, annealing, tempering, isothermal annealing and stress relieving applications.
