Three electrically heated RO pit furnaces with air-cooled fans have been shipped from Riverside, MI. The furnaces will be used for heat treating various steel components.
“These pit furnaces are designed for a nitrogen atmosphere,” commented Kelley Shreve, general manager at Lindberg/MPH. “They have been designed to utilize three independent heating zones for optimal temperature uniformity and meet AMS 2750G Class 3.”
These heat treating pit furnaces from have a maximum temperature rating of 2,000°F and are designed to handle a wide range of part sizes. Two of the units have work chamber dimensions of 28″ x 36” and a maximum gross workload of 2,000 lbs. each. The third furnace has work chamber dimensions of 60” x 109” and a maximum gross workload of 20,000 lbs.
All of the pit furnaces have pneumatically operated lids with three-way hand control valves and limit switches that disconnect power to the heating elements when the covers are open. The pit furnaces are electrically heated with heavy duty rod overbend heating elements.
