Mechanized Pacemaker Integral Quench Furnace

The Lindberg Pacemaker® is a highly productive and efficient integral-quench furnace available in either gas-fired or electric models. It is the centerpiece of a complete heat-treating 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 both automatically 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.
• Lindberg Quench Guard® quench water detection device.
• 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.
• Recuperative vertical radiant tubes for gas-fired models.

Options

• Upper atmosphere cooling: Oil-cooled double walled chamber above the quench, cools the workload under protective atmosphere. Atmosphere cool/oil quench selector switch. Upper cooling is available with or without a recirculating fan to accelerate load cool down.
• Hot oil quench with additional immersion heaters and insulation lagged to the quench tank shell.
• Variable speed quench agitation.
• Enhanced furnace control components.
• Complete system automation to suit your unique
  requirements.

Applications

• Annealing
• Carbonitriding
