New Vacuum Furnaces

Coidan Graphite Products represent Seco Warwick for their range of Vacuum and Atmosphere furnaces in the UK, Seco Warwick are one of the largest furnace manufacturers in Europe and are sure to have the type of furnace you require within their product range - see www.secowarwick.com.pl

Seco Warwick in conjunction with Coidan Graphite Products offers vacuum heat treating furnaces for hardening, tempering, annealing, solution heat treating, brazing, sintering, carburizing, carbonitriding, high vacuum, CVD-graphitizing and degassing.  SECO/WARWICK has built some of the largest and technically advanced vacuum furnaces in operation today, developing advanced technologies like Universal HPQTM (High Pressure Quench), PreNit® & FineCarb® LPC vacuum carburizing, fully automated control systems and modeling software. Vacuum furnace configurations are available for vertical, horizontal and elevator style furnaces. Both cylindrical and rectangular hot zones with metallic or graphite heating elements are available. If your budget is not up to a new furnace Coidan Graphite Products have a stock of used and refurbished vacuum furnaces which may meet your needs.
