Vac Aero International Inc., Oakville, Ontario, Canada, through its affiliate, Vac Aero Europe S?rl, reached an agreement to market a new gas probe developed by SCR S.A. of Switzerland. The probe permits in situ, real-time monitoring and flow regulation of individual process gases to control nitriding potential during gas nitriding and nitrocarburizing. Vac Aero International has also recently obtained the global rights to manufacture gas nitriding and nitrocarburizing furnace systems based on the Guler (Thermovac) design. The SCR gas probe and control system will be offered as a standard feature on Vac Aero nitriding equipment, but can also be retrofitted on existing furnaces.
