    Leading innovations in digital scroll technology Emerson’s scroll compression technology, introduced in 1987, revolutionized the compressor industry. In 2012, Emerson’s 100 millionth scroll compressor rolled off the assembly line. It marked an important milestone for Emerson as a world leader in the development and application of scroll technology.

    Main features and advantages:

    • 10-100% stepless capacity modulation, ensuring precise temperature control and reducing goods weight loss

    • Less complicated compared to variable speed technologies

    • More reliable compared to other modulation technologies due to elimination of oil return issues

    • Proven scroll technology paired with mechanical unloading system provides greater reliability and efficiency

    Energy-efficient refrigeration through digital modulation

    Today, Emerson is the world’s largest manufacturer of refrigeration compressors, underscoring Emerson thrust of ensuring food safety and protecting the environment. Leveraging on Emerson’s vast global network and R&D resources, the company also continues to develop the ultimate in climate technology for various businesses. Emerson helps provide solutions to achieve high efficiency systems for cold storage warehouses, supermarkets, quick service restaurants, meat trading and processing facilities, seafood import and export establishments, agricultural depots and retail outlets - green technologies with less environmental impact.

    With today’s growing need to address energy efficiency and precise temperature control, Emerson provides ZBD compressors - digital scroll technology in a simplified, compact design yet very reliable. Precise capacity modulation control proves beneficial in a number of applications, including cold rooms that needs accurate temperature control as well as multiple evaporator systems with varying cooling loads. The ZBD features continuous capacity modulation range of 10-100%. Compared to cycling compressors, the stepless capacity control of the ZBD enables for a smoother and a more accurate approach to load matching. Furthermore, the streamlined design of digital scroll technology requires less control boards than variable speed compressor technology which contributes to its high reliability and simplicity in operation.
