Throwback and Prospect: 30 Years Passion for Flow

1989 - It all started with profound knowledge

The small engineering office Werner Heinze becomes the em-tec GmbH. Through decisive developments for a medical device manufacturer of heart-lung machines, the highly professional company makes a name for itself. To this day, the so-called HL 20 is considered the standard within the field.

1990s - Development, establishment and achievements

em-tec accompanies numerous new developments within medical technology with the main focus on heart-lung machines. em-tec's centrifugal blood pump receives FDA approval and is produced to this day. The company is rated as expert for ultrasonic technologies and introduces a certified QM system with experience in regard to the approval of medical products.

2000s - From supplier to manufacturer within the medical market

A new chapter begins: based on the many years of experience with ultrasonic flow measurement, em-tec develops numerous own products and components for flow measurement by the means of sensor technology, which is still successfully merchandized.

2010s - En route to the top

The product portfolio in the field of non-invasive flow measurement continues to grow due to innovative developments and em-tec establishes itself as world market leader for flow measurement within extracorporeal systems.

2020s - Growth for the future

To satisfy the needs and demands of the order situation as well as the new corporate structure with its three divisions MEDICAL, BIOPROCESSING, and ENGINEERING, the company needs both manpower as well as more space for production. Consequently, em-tec GmbH will move into its new, state-of-the-art building with space for up to 150 people in 2020.
