BMI, a Tenova company, commissioned its first set of twin vacuum furnaces at a customer’s site. The furnaces work on a single pumping station and are designed for tempering. 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 reduces electricity consumption and also minimizes the maintenance costs of the pumps.
BMI, headquartered in Lyon, France, designs and manufactures vacuum furnaces for the heat treatment of metal parts. Besides commercial heat treatment, the company’s furnaces are mainly used in the aerospace and tooling industries.
