BITZER US, Inc. is a subsidiary of Germany based BITZER SE, the world’s largest independent manu-facturer of A/C and Refrigeration compressors with sales companies and production sites for reciprocating, screw, and scroll compressors as well as pressure vessels all over the globe. Headquartered outside Atlanta and with three manufacturing plants in the U.S., BITZER US is well positioned in 2015 to continue its extraordinary growth in an industry that demands quiet, high efficiency products and “green” solutions. industrial refrigerated warehouse systems, marine systems, etc. The BITZER brand has always been synonymous with high quality and reliability, but our OEM customers now promote BITZER for its techno-logical superiority and overall value. By optimizing its compressor efficiency based on the application, BITZER is able to outperform the “one-size fits all” model that is standard in our industry. We have designed Screw and Scroll compressors that are optimized based on whether they are applied to air-cooled condenser (SCT > 110°F) systems or water cooled (SCT < 110°F) systems. The resulting IPLV of systems using these optimized models is significantly enhanced. Both compressor types can accommodate a VSD if desired. President, BITZER US, Inc. Peter Narreau BITZER’s new CRII capacity control for its semi-hermetic ECOLINE compressors can unload down to 10%, and its Varispeed model, which includes an integrated VSD, can operate from 25 – 87Hz. Ensuring best in-class performance in Screw Compressors, BITZER has launched a line of Screw Compressors with integrated VSDs. Even these are optimized based on the application. BITZER US, Inc. Headquarters in Flowery Branch, GA. BITZER is able to outperform the “one-size fits all” model that is standard in our industry. To further increase IPLVs, BITZER has a patent pending on an Advanced Header Technology (BAHT) that enables OEMs to mix numerous combinations of Scroll Compressor sizes and frames to achieve optimum performance in their systems. For example, an OEM can now combine a 15-ton scroll (GSD6 frame size) with a 25-ton scroll (GSD8 frame) and can add a VSD on the smaller model to achieve the highest efficiency while precisely matching the cooling load. As the “green” movement evolved in Europe in the 90s, BITZER became a pioneer in the manufacture of compressors using natural refriger-ants like CO 2 and ammonia. Today, BITZER provides both subcritical and transcritical CO 2 compressors to the industry as well as complete Ammonia Compressor Packages. Please visit or email us Peter Narreau, president of BITZER US, Inc, states “BITZER has met the challenge of providing the market both high efficiency compressors in addition to those that use natural refrigerants.” BITZER’s OEM customer base in the U.S. includes manufacturers of liquid and air-cooled A/C chillers, modular and process chillers, commercial rooftop units, supermarket mechanical rooms (racks), condensing units, ultra-low temp units, commercial and ADVERTISEMENT
