cryologo

The CryoFurnace

Multiple tempers are achieved by a ramp soak controller, leaving the CryoFurnace to stand alone in thermal cycling. The CryoFurnace is the first and only cryogenic tempering chamber to have an upper limit of +1200°F. CryoFurnaces are used for a variety of heat-treating applications such as atmospheric tempering, stress relieving, and deep cryogenic tempering. The added benefit of 

inert atmosphere control will make these systems your most versatile piece of equipment. All of our furnaces are built to satisfy the extreme demands of daily operating conditions found in the professional heat-treating environment. Our never-ending emphasis of incorporating customer feedback assures that DMP CryoSystems will continue to lead the way in the heat treating market place.
