Process Control Upgrades for any Vacuum Furnace Brand
Considering an upgrade to your VAC AERO or any other vacuum furnace control system? The Honeywell HC 900 Hybrid Controller is one of the most powerful control systems on the market today. The HC900 integrates with Honeywell Experion HS software running on a Windows 7-based PC to provide Supervisory Control and Data Acquisition (SCADA). The control system can connect remote users, link multiple furnaces together, or to other operating systems in a facility. It is programmable, logic-based and comprised of proven hardware components, suitably hardened for an “industrial shop” environment.

Shell & Tube Heat Exchangers — Methods to Seal Tube-to-Header Joints
Brazing has become more and more the desired joining-method to “seal” these heat exchangers from any internal or external leaks. In this article, we look at some of the internal characteristics of S&THE’s, options for sealing them to make them leak-tight, and some important requirements for proper joint design so that brazing can be used to cost-effectively make many tube-to-header leak-tight joints in S&THE’s at the same time!

Vacuum Pump Tech: Education & Training
Oil sealed rotary vane pumps (aka rotary vane pumps) are the primary pumps on most vacuum systems used in the heat treatment industry. They are also referred to as a “backing” pump when used in combination with a booster pump, or with both a booster and secondary (“high vacuum”) pump, typically a diffusion style. A rotary vane pump can also be used alone when high vacuum is not required and slower pump-down is acceptable.

Vacuum Heat Treating: Education & Training
Vacuum GaugesA Vacuum Gauge is a pressure measuring instrument that measures pressure in a vacuum (i.e., in a vessel operating at sub-atmospheric pressure). Depending on the type of vacuum system (Fig. 1) and the required operating vacuum level, different vacuum gauges are required, often in combination with one another, to accurately determine and/or control the vacuum level of the chamber at any given moment in time.
