Emerson’s commitment to environmental responsibility extends to the new technologies, products, and services we design and deliver to our customers. By anticipating their energy efficiency needs, Emerson is ready when our customers look to implement new solutions to help reduce energy costs and emissions that impact the environment.
Here are just a few of many examples of how Emerson businesses are developing technologies to meet our customers’ demand for high quality, cost-effective energy efficient products.
More energy efficient cooling systems.
Emerson is the manufacturer of Copeland Scroll® and Copeland Digital Scroll™ compressors, the world's leading scroll compressors used in powering energy-efficient central air conditioning, heat pumps and refrigeration systems. In 2005, Emerson introduced Copeland Scroll® compressor technology optimized to help system manufacturers meet and exceed the federal 13 SEER (seasonal energy efficiency ratio) standard for central air conditioners that went into effect in the United States in January 2006.
With 20 major design improvements and nine new patents pending, this next generation of Copeland Scroll compressor technology increases the efficiency of the compressor by up to seven percent and reduces sound up to 50 percent. Improved temperature protection, enhanced bearing systems and standardized parts all further improve product quality and enhance scroll reliability even further.
Better heat pump technology.
Heat pumps account for 80 percent of residential heating and cooling systems sold in China. However, conventional heat pumps do not effectively handle the heating requirements during northern China’s cold winters. Consequently, many homes and buildings in that region have a second heating system installed (usually a hot water boiler system).
In 2006, Emerson introduced Copeland Digital Scroll Heating™ technology for heat pump systems in China. With Copeland® Digital Scroll™ Heating technology, heat pump systems operate better and more efficiently in cold temperatures – and the supplemental heating system for a home is not needed.
Chlorine-free refrigerant.
Emerson is transitioning its compressor products to using chlorine-free R-410A refrigerant. R-410A refrigerant is the chlorine-free, environmentally friendly refrigerant that is expected to replace R-22, a chlorinated refrigerant that will be banned from use in new air conditioners in 2010. The company now has the world’s broadest product lineup of scroll compressors designed for use with R-410A refrigerant and has an estimated four million installations as of January 2007.
Facility energy management.
Emerson’s E2 Facility Management System is an electronic control system that integrates the control of all lighting, refrigeration and HVAC equipment at a store, allowing multiple facilities to be monitored from a central location for enhanced energy control and management.
Emerson’s patented E-Commissioning® service provides a process for systematically examining, testing, and adjusting refrigeration, HVAC, lighting and other building equipment to improve energy efficiency and lower energy costs.
Emerson energy management technology products and services have been installed in more than 20,000 facilities worldwide (including supermarkets, convenience stores, gas stations and other retailers). Use of Emerson’s products and service solutions have helped global retailers reduce their annual energy and maintenance expenses across their enterprise by as much as 15 percent or more, resulting in an estimated savings of seven billion kilowatt hours of electricity annually.
Promoting energy efficiency in China.
Emerson Climate Technologies has supported government initiatives in China to establish suitable energy efficiency standards. Emerson is cooperating with the government in the education of consumers and shop salespersons in the benefits of purchasing and using energy efficient air conditioning systems.
Emerson is working with Asia-based OEMs (original equipment manufacturers) to incorporate energy-efficient Copeland Scroll® technology into their locally based solutions for high efficiency air conditioning and refrigeration systems.
NEMA Premium motors.
Emerson is the largest manufacturer of electrical motors in the world. Emerson Premium electric motors are built to meet or exceed the National Electrical Manufacturers Association (NEMA) premium efficiency standards.
Emerson Premium motors are expected to save customers an estimated 5,800 gigawatts of electricity over the next 10 years. This translates to preventing nearly 80-million metric tons of carbon dioxide from entering our atmosphere, which is the equivalent of keeping 16-million cars off the road.
Wind turbine technology.
Leroy-Somer, a manufacturing unit of Emerson Industrial Automation, provides 3MW generators for the leading global manufacturer of windmills.
In addition, Jaure/Kopflex couplings from Emerson, are found on wind turbines producing from 300KW to 5MW output. More than 3,000 wind turbine generators have been built and sold, helping to deliver electricity to the national grid for more than 28 countries in Europe and around the world.
Gear technology for ethanol facilities.
Browning helical shaft mounts, produced by Emerson Power Transmission, are now specified by leading ethanol processing OEMs to meet the growing demands for agricultural based renewable energies.
Browning products are used on hammer mills which produce milled aggregates early in ethanol processing and also on drum dryers which are found at the very end of the production process. Browning's highly efficient helical gearing solution combined with grain handling application know-how is supporting the rapid growth of this industry.
Energy efficient motors in Europe.
Emerson’s Leroy-Somer division saved customers an estimated 3,500 gigawatt/hours of electricity between 1999 and 2004 by replacing its lineup of Eff3 motors with higher efficiency Eff2 motors and the introduction of Super Premium Eff1 motors.
Current market expectations forecast that Eff1 motors will have replaced the Eff2 range by 2012, thus saving a further 4,000 gigawatt / hours over this period. This translates to preventing over 100-million metric tons of carbon dioxide from entering our atmosphere, the equivalent of keeping 20 million cars off the road.
Energy efficient AC drives for motor control.
Over the past five years, Emerson’s Control Techniques division has delivered over 700,000 energy-efficient AC drives to control motors used in industrial applications such as fans, pumps, compressors, conveyors and mixers. AC drives reduce energy wastage in these applications by changing the motor speed so that the electrical energy consumed by the motor is no more than required.
Safe, efficient energy production facilities.
ASCO Valve, another Emerson division, provides several technologies used in the energy production industry. ASCO Valves are used in nuclear power plants to provide safety and balance to plant systems.
ASCO Valves are also used throughout biodiesel and ethanol processing facilities to control the production of these alternatives to petroleum-based fuels. The U.S. Department of Energy estimates that the use of ethanol fuels reduces emissions of greenhouse gases in vehicles by 52%.
Cleaner coal burning at power plants.
Emerson’s PlantWeb® digital plant architecture and Ovation® expert control system – plant process and automation technologies – are helping the process industry around the world operate their plants more efficiently, more safely, and with less energy use.
For operators of coal-fired power plants, the productivity payback in using these Emerson technologies helps enable them to install and operate new clean coal-burning technologies that reduce pollutants.
With PlantWeb, power generators can slash millions of dollars off the design, engineering, construction and start-up costs of new coal-fired plants, as well as the cost of installing new scrubbers at existing plants.
Emerson’s Rosemount Analytical environmental solutions for continuous emissions monitoring systems (CEMS) assist power-generation facilities in reducing NOx, CO2 and CO emissions. In addition, its CEMS solutions optimize boiler efficiency and reduce fuel consumption for power plants, while keeping them in regulatory compliance as well.
More energy efficient data centers.
As worldwide use and reliance on telecommunications networks and the Internet grows, data centers are doubling in size every 24 months and servers are becoming more powerful. With increased size and capacity comes more heat generated from servers -- and greater power and cooling needs.
Emerson Network Power, which provides reliable power and backup power technologies for data centers, is partnering with industry leaders such as Intel, Dell, IBM and Sun, to identify solutions to reduce server energy use and increase equipment efficiency.
