Leading Innovations in Digital Scroll Technology
Emerson Climate Technologies has revolutionized the industry with the introduction of its scroll technology, which was launched in 1987.
In 2012, Emerson produced its 100 millionth scroll - a signicant achievement and further demonstrating Emerson’s position as a world
leader in the development and application of scroll technology.
Energy-efcient Refrigeration Through Capacity Modulation
Today, Emerson is the world’s largest manufacturer of refrigeration compressors, underscoring Emerson Climate Technologies’ 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 efciency
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 efciency and precise temperature control, Emerson developed ZBD compressors – digital
scroll technology in a simplied, compact design that is very reliable.
The ZBD features continuous capacity modulation range of 10-100%. This eliminates hot gas bypass, which causes waste of electricity,
and complications arising from variable speed drives. Precise capacity modulation control proves benecial in a number of applications,
including precise temperature control for precision cooling and humidity control as well as parallel compressor operations or rack systems
– intermediate and more precise part load operation of a compressor to perfectly match varying evaporator loads. Compared to cycling
compressors, smoother and more precise load matching is enabled by stepless capacity control with the ZBD.
Key Features and Benets
•Digital Scroll technology provides higher efciency compared to hot gas bypass systems or
compressor cycling
•Less complicated compared to variable speed technologies
•More reliable compared to other modulation technologies due to elimination of oil return issues
•Suitable for rack systems due to its varying load requirements
•Proven scroll technology paired with mechanical unloading system provides greater
reliability and efciency

Digital Scroll Advantage for Rack Systems
Digital scroll compressors having modulation capabilities from 10%–100% naturally t refrigeration rack systems. Rack systems need to
fulll varying evaporator load requirements due to changing case loads, not to mention variations due to cases undergoing routine defrost.
This can be attained by complementing xed-speed compressor racks with a digital scroll of the same capacity. The refrigeration load will
be matched by running xed-speed compressors to handle the base load and the peaks by the digital scroll. This leads to a smooth and
almost constant system suction pressure (see charts below). Compared to xed-speed scroll racks where unloading is achieved by cycling
the lead compressor, this results in a saw tooth prole of the system suction pressure and will reduce the life of the lead compressor due to
frequent on and off action. Fluctuating suction pressures lead to varying evaporator temperature and humidity conditions—a condition
that is not advisable for refrigerated products.
