SHEL LAB clean air ovens incorporate all the special features needed for high temperature cleanroom work: an all heliarc-welded type 304 stainless steel interior, two adjustable perforated stainless steel shelves, rapid heat recovery, and two separate LED digital displays for time and temperature that show set point or up-to-the-second process information. The PID (Proportional Integral Differential) controller provides a 24-step ramp and soak, 0.1°C control, and multiple levels of operator access. A sealed membrane touch-pad control panel protects the controllers.

A nitrogen inlet port for purging is standard to prevent contamination. SHEL LAB cleanroom ovens are made with 3.5 inches of high-temperature, wrap-around insulation and a high-temperature silicone rubber door seal.
