Clean Room Digital Forced Air Oven - 3.9 Cu. Ft. - 20 to 270°C Range

SMO5CR-2 cleanroom oven incorporates all the special features needed for high-temperature cleanroom work: stainless-steel interior, adjustable perforated stainless-steel shelves, and rapid heat recovery.
The Watlow controller is capable of a 40-step ramp and soak profile or 4 files with 10 steps per file. SMO5CR-2 cleanroom ovens are made with high-temperature, wrap-around insulation, and a high-temperature silicone door gasket.
SMO5CR-2’s adjustable air intake and exhaust ducts are easily removed for cleaning. Chamber air is continually passed through the Class E11 efficiency particle filter in SMO5CR-2’s horizontal airflow regimen; this contrasts with other oven designs that merely filter the incoming air once. A nitrogen inlet purge port is standard to reduce external air ingress and the risk of contamination.
