From French vacuum furnace builder BMI one of the largest manufacturers in Europe comes this idea. Our first impression is that this is either a very, very good idea or a very, very bad idea. We welcome your thoughts and look forward to hearing more about this idea.
“For several years now, BMI has been working on monitoring the energy consumption of it’s vacuum furnaces. The investment cost is an important criteria indeed, but nowadays customers are just as interested in the operating costs. That’s why at BMI, we work on improving our equipment by reducing the operating costs. Thus was born BMI’s first twin furnaces working on a single pumping station. Typically during a heat treatment cycle, the pumping phase lasts only 30 minutes. Therefore, it is smarter to use only one pumping group for two furnaces, working alternatively on one furnace or the other. This allows not only to reduce electricity consumption but to reduce also the maintenance costs of the pumps. The first set of B54R-TWIN furnaces has just been commissioned at a customer’s site.”
