Lindberg/MPH announced the shipment of an electrically heated, large chamber utility box furnace to an automotive supplier. The furnace will be used for batch testing aluminum castings on a daily basis at a temperature of 500°C.

The work chamber dimensions of this heat treat furnace are 24” W x 24” D x 24” H and it has a maximum temperature rating is 1100°C. The Large Chamber Utility Box Furnace is available in nine chamber sizes to meet demanding applications. The furnace utilizes vacuum formed ceramic fiber insulation with low heat loss for operating economy and minimum heat storage which results in rapid heat up and control response. To ensure even less heat loss, a double steel shell construction is used to create a low temperature outer surface. The insulation and heating elements maintain uniform heat distribution for an energy efficient design.

“At Lindberg/MPH we strive to find the best heat treat solutions for our customers. For this project, we designed a custom heating system to minimize heat loss and providing energy efficiency.” Andrew Paul, Sales Engineer
