Attitudes towards environmental awareness as well as social responsibility have steadily grown in the refrigeration industry. As an essential feature refrigeration plants must operate in a hermetically sealed way and thus, the importance of tightness has become more and more important for engineering, ecological and economical reasons. Therefore, both safety in plants as well as environmental protection play an important role in business strategy. Not only ice-cream and frozen foods need to be cooled, but almost every food. Typical application ranges include rail vehicles, toboggan-runs, bob runs, breweries, etc. in which HERMETIC pumps have been successfully used for reliable cooling of plants and production processes. HERMETIC has been dedicated to the development and production of hermetically sealed pumps for a period of 60 years. HERMETIC pumps are designed for applications in the chemical and petrochemical industry, as well as for process technologies. The refrigeration industry also benefits from this experience made in these industries. There are more than 90.000 HERMETIC pumps installed in refrigeration plants worldwide.
