Sealed Quenching Furnace Machine

Indomen sealed quench furnace is a highly productive and efficient integral-quench furnace available in either gas-fired or electric models. It is the centerpiece of a complete heattreating system. The furnaces feature obstruction-free work chambers, large capacity re-circulation fans, and strategically located heated sources to ensure rapid heat transfer, low energy use, and excellent temperature and carbon uniformity. A size and in-out configuration is available to fit your needs.

Features/benefits
 Fully automatic movement of the load within the furnace,including quench.
 Programmable logic controller eliminates sequencing circuit relay maintenance.
 Temperature and atmosphere carbon potential are bothautomatically controlled.
 A two-pen strip chart records both furnace temperature and percent carbon.
 Preheat oil quench with immersion heaters, temperature and excess temperature controllers  Oil level sight gauge and level alarm.
 Air-to-oil quench cooling heat exchanger.
 Flowmeters for endothermic gas, natural gas additions,ammonia gas additions, and air for carbon burnout.
Emergency nitrogen gas purge circuit activates on power failure or loss of atmosphere.
 Scr power control for electrically heated models.
