A laboratory in California will use a Class 1, Division 1 – Class 2, Division 1-rated cabinet oven designed by JPW Industrial Ovens & Furnaces, Trout Run, Pa., for munitions testing.

The oven was built to be explosion-proof and earned an NRTL certification. Engineered as a low temperature unit, the oven operates at 250°F (121°C) or below. The sheath temperatures of the heaters are controlled, so the interior of the unit cannot get hotter than the flashpoint of the materials contained. The oven also has a solvent-rated interior, and special attention was given to create a nonsparking interior design.
