Fann® Model 704ET and Model 705ET Roller Ovens are primarily designed for laboratory use. These roller ovens provide an excellent method of aging fluid samples. High-temperature Aging Cells containing sample fluids are placed in the roller oven where they are subjected to moderate heat and agitation (rolling) on power driven rollers. Samples may also be heated without rolling (static aging). These Roller Ovens are constructed of polished stainless steel and other corrosion resistant materials. They are well insulated and the temperature is regulated by a digital temperature controller that supports Fahrenheit and Celsius measurements. A programmable timer can be set for delayed start, delayed stop, and immediate start. A voltage selector allows operation at 115VAC or 230VAC.
Each roller oven features the Enhanced Safety System: This feature prevents thermal runaway. An over-temperature controller shuts off power to the oven heaters when the internal oven temperature reaches the maximum safe limit (500°F).
