Use of natural refrigerants in HERMETIC refrigeration pumps

Over the past few years, a trend shift has become increasingly evident: Environmental awareness as well as social responsibility have steadily grown in the refrigeration industry. Proven synthetic refrigerants as well as natural refrigerants like ammonia and carbon dioxide have now also penetrated the market. The operation of ammonia and CO2 refrigeration plants is considered climate-neutral and thus environment-friendly, as they do not contribute to ozone layer destruction. In addition, ammonia and carbon dioxide are hardly flammable, which ensures the safety of your refrigeration plants.

As a result of this ecological change, the demands concerning refrigeration equipment and components have changed accordingly. Higher design pressures, new sealing materials and Modular designs are now required. Low life-cycle costs and increased energy efficiency are demands that are implemented in our pump technology. As an essential feature, refrigeration plants must operate in a hermetically sealed way. Thus, the importance of leakfree operation 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 strategies of plant operators. HERMETIC ammonia and CO2 refrigeration pumps are energy-efficient, ecologically responsible and absolutely safe. With a highly innovative refrigeration technology, HERMETIC pumps guarantee highest quality and safety standards and are exclusively designed to meet our clients’ needs.

With decades of experience, innovation and continuous technological improvement, HERMETIC has been dedicated to the development and production of hermetically sealed pumps for more than 60 years. Plants in the chemical and petrochemical industry, as well as process engineering systems, are our main application focus. We successfully apply our experience made in these areas in the refrigeration industry. Worldwide, we provide refrigeration plants with our high quality refrigerant pumps. Currently, there are more than 150,000 HERMETIC pumps installed in refrigeration systems around the globe.

Pump technology has been our passion and inspiration for more than 150 years!
