BMI Twin Furnaces for Energy Saving

The first set of B54R-TWIN – vacuum furnaces for tempering – has been commissioned to BMI, a Tenova company.

For several years now, BMI has been working on monitoring its machines’ energy consumption. The investment cost is of course an important criterion, but customers are always more interested in the operating costs of their future machines. That's why at BMI, we work on improving our equipment by reducing the operating costs

Following this approach, BMI's first twin furnaces working on a single pumping station were developed. During a heat treatment cycle, the pumping phase lasts only 30 minutes. Therefore, it is more efficient 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 also to minimize the maintenance costs of the pumps. 

The first set of B54R-TWIN, vacuum furnaces for tempring, has now been commissioned on a customer's site.

In order to push further the optimization of energy consumption, our Engineering Department is also working on qualification phases of vacuum insulation (working on various material and thickness combinations). 

With headquarters in Lyon (France), BMI, a Tenova company, is a leading designer and manufacturer of vacuum furnaces for the heat treatment of metal parts. Besides commercial heat treatment, BMI’s vacuum furnaces are mainly used in the aerospace and the tooling sectors.
