JSOF-Series Forced Convection Ovens utilize a motorized fan to force air circulates across heating element to supply hot air into the chamber. The fan allows more consistent temperature distribution of the chamber for applications in which good temperature uniformity or faster heat up and short drying time are needed.
Performance
– Control Temperature Range from ambient + 10 °C to 250 °C
– Forced air convection for fast drying application
– Aero-dynamic chamber designed with circulation blower to achieve superior thermal uniformity
– Separate heating compartment located on back wall for contamination free and maintenance free
– 50mm thick high thermal efficiency mineral wool with woven aluminum barrier sheet saves energy and less dust
