North American Manufacturer Orders Hot Zones
VAC AERO shipped four complete replacement hot zones for various sized furnaces to a North American manufacturer. The hot zones feature unitized construction for easy removal and maintenance. The lightweight design’s low thermal mass enables faster quenching and longer life. The heat-shield package consists of three layers of 0.5-inch-thick graphite felt and an inner reflective layer of graphoil-bonded carbon composite, which provides added protection and enhanced reflectivity.
The graphite felt does not shrink, which minimizes heat leakage and contributes to stable uniformity throughout its useful life. The heat-shield package is supported by a 14-gauge stainless steel assembly that uniformly distributes the quenching gas to the workload.
