VAC AERO Receives Order for Replacement Hot Zone
Burlington, Ontario, March 23, 2016 – VAC AERO has recently received an order for a complete all-metal hot zone refurbishment for a customer in Canada, in the Aerospace Heat Treatment sector. The retrofit work is for a horizontal furnace. The hot zone 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 one layer of .020” thick lanthanted molybdenum (Mola) sheet backed by one layer of .010” thick molybdenum sheet, and three layers of .014” stainless steel sheet. The heat shield package is supported by a 14 gauge stainless steel assembly that also acts as a manifold to distribute the quenching gas uniformly throughout the workload. Built for rugged usage and low maintenance VAC AERO hot zones feature unitized construction for easy removal and maintenance.

VAC AERO Ships Hot Zone Replacements for Two Furnaces
Burlington, Ontario, January 18, 2016 – VAC AERO has recently shipped two complete replacement hot zones for two furnaces to be delivered to a Canadian 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 half inch thick graphite felt and an inner reflective layer of graphoil bonded carbon composite that 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 ga. stainless steel assembly that uniformly distributes the quenching gas to the workload. Some ongoing improvements on VAC AERO’s hot zones include improved durability, thermal efficiency and extended hot zone life.

VAC AERO Ships Vertical Vacuum Furnace to Asian Aerospace Company
Burlington, Ontario, October 19, 2015 – A VAV6648 HV-2 bottom loading vacuum furnace with a work chamber of 66″ diameter x 48” high has been shipped to an international Aerospace company. The furnace includes a high vacuum pumping system and a 2-bar argon quench system designed to incorporate unique performance features; the cooling nozzle configuration and location have been engineered to improve gas penetration into the workload, gas velocity and cooling speed. The energy-efficient graphite hot zone lightweight design and low thermal mass enables faster quenching and longer life. The heavy duty hearth is constructed with quickly removable rails of pure molybdenum capable of handling distributed loads of up to 4400 lbs. The furnace operating system is based on VAC AERO’s versatile Honeywell HC900 interactive hybrid control package with SCADA and complete network integration capabilities and remote monitoring and control.

VAC AERO Launches a New Vacuum Pump Technology Column with Dan Herring in collaboration with Edwards Vacuum!
This is the first in a new series of articles to be entitled “Practical Vacuum Pump Practice with Dan Herring.”
Burlington, Ontario, August 17, 2015 – A new column, written by vacuum heat treating expert Dan Herring “The Heat Treat Doctor”® in collaboration with Edwards Vacuum will be published monthly and offer helpful tips and techniques on vacuum pumping systems to a worldwide audience of individuals using all types of vacuum equipment. The first article will appear in the September 15th “What’s Hot!” newsletter. This VAC AERO exclusive publication launched back in September 2007 and contains hundreds of archived articles can now be found in the “Resources” section of the VAC AERO website where anyone can sign up for the monthly newsletter.
The purpose of this column is to inform, educate and answer questions for anyone who owns and operates vacuum equipment or is thinking of doing so, focusing on commercial and captive heat treaters; engineers, metallurgists, maintenance personnel, supervisory staff, heat treat operators, quality control and quality assurance personnel, and anyone else who is interested in the subject of vacuum pumping and vacuum processing. Dan will draw upon his vast experience as well as work with leading Edwards’ experts in the field of vacuum technology to provide examples of the concepts being discussed.
Keeping pace with the development of new vacuum processing technologies is the reason VAC AERO takes pride in its continued support of the metal treating community by helping to promote, collaborate and assist others in their search for solutions on important issues in the practice and application of vacuum processing. The aim of this column as well as the three others is to continue to provide our readers with important and relevant knowledge-based articles and information that they are constantly seeking.
