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.
Applications:
Annealing
Carbonitriding
Carburizing
Tool Steel Hardening up to 1850°F
Normalizing

Small shaker hearth furnaces type Vi are mainly used for hardening parts that, because of their small size, would cause handling problems on a mesh belt or when production volume is too small to justify the use of a mesh belt furnace.
This type of furnace is ideally suited for watch parts, fine mechanical parts, sewing and knitting needles and similar.
Typical heat treatment applications, at temperature up to 950 °C include:
- Hardening or case hardening, with oil or polymer quench.
- Austempering and Martempering with hot oil or salt bath quench.
- All these treatments are carried out under controlled atmosphere
