Thermal Product Solutions ships Gruenberg conveyor oven to firearms maker


Thermal Product Solutions, a global manufacturer of thermal-processing equipment, announced the shipment of a Gruenberg conveyor oven to an ammunition manufacturer. This conveyor oven will be used for annealing and stress-relieving brass castings.

The maximum temperature rating of this heat treat oven is 850 degrees Fahrenheit, and the work chamber dimensions are 24” W x 105.5” D x 16” H. A variable speed conveyor system provides the operator with precise process control. The equipment design consists of one oven module, constructed from a structural steel frame that supports the chamber liner and the exterior sheet metal. All interconnecting struts are non-continuous to keep the exterior cool.

The conveyor oven has plug-style circulation and heating equipment. There are three identical plugs on the unit. This design allows the replacement of heaters away from the unit by removal of the plug as well as quick interchange if an extra plug is available.

“It was important for our customer to minimize equipment downtime. Gruenberg designed the unit to have swappable heater and circulation blower plugs, as well as supplied an extra plug with this system. If a heater needs to be replaced, or if one of the air circulation blowers fails, the plug can quickly be replaced,” said Blake Lawson, applications engineer

Unique features of this Gruenberg conveyor oven include:

  • Set of adjustable leveling feet.
  • Variable-speed conveyor system.
  • Vertical up airflow design to maximize heating rates and uniformity.
  • Yokogawa UP55A programmable controller.
  • Plug-style heaters and recirculation equipment.
  • Cooling section.
  • Bearing cooling blowers.
