Danfoss, a leading manufacturer of high efficiency electronic and mechanical components and controls for air-conditioning, heating, refrigeration, and motion systems, has been recognized by a panel of ASHRAE members with a 2015 AHR Expo Innovation Award, green building category, for its Turbocor VTT series of oil-free, variable speed, magnetic bearing centrifugal compressors. The company also received an Honorable Mention in the cooling category for its new ETS Colibri® electronic expansion valve. Together, this marks the 17th and 18th time Danfoss has been recognized in the AHR Expo Innovation Awards program over the course of 12 years.
“We are honored to receive the 2015 AHR Innovation Award,” commented John Galyen, president, Danfoss North America. “Innovation is rooted deep in our culture. For more than 80 years, Danfoss has been focused on engineering innovative, reliable technologies that reduce energy use and environmental impact – and, today, we remain committed to product development and partnerships that enable our customers to meet the challenges and standards of tomorrow.”
Award Winner: Turbocor VTT Series of Compressors
As the green building category winner, Danfoss Turbocor VTT series of compressors introduces IntraFlow™, an innovative and patent-pending technology that improves efficiency and provides an extended stable operating range while simplifying capacity control. IntraFlow™ eliminates the need for inlet guide vanes or mechanical variable geometry diffusers, allowing VTT compressors to offer both superior full-load and part-load performance and enabling chiller manufacturers to achieve the latest efficiency standards.
Intended for water-cooled chillers and with capacities of 350 tons per compressor, Turbocor VTT – or Variable Twin Turbo – compressors are ideal for commercial air-conditioning or process cooling chillers reaching up to 1,000 tons or more. New drive technology featured on the compressors is exclusive to the VTT series, and is the result of integrated R&D efforts blending Danfoss’ extensive expertise and capabilities in high-efficiency compressors and variable frequency drives for the HVACR industry. The VTT drive will have the superior reliability and performance that has come to be expected from Danfoss, in a small frame size made achievable only with refrigerant-controlled heat removal.
Because the compressors are oil free, end users experience lower maintenance costs associated with traditional systems that can suffer from repair chronic lubrication problems.
“The Turbocor VTT series of compressors takes the benefits of magnetic bearing technology up into larger capacity ranges where our current TT series leaves off. Plus, the energy efficiency improvements on this new series of compressors enable our OEM partners to meet the new ASHRAE 90.1-2015 efficiency standards,” said Frank Ford, director of product management for Danfoss Turbocor Compressors. “We are excited that this year’s panel of judges has recognized the innovative and efficient capabilities of the VTT series of compressors.”
“We are very honored to receive this prestigious award. We have a strong sense of responsibility to continue to shape the HVAC industry so that we can do more with less energy via innovation,” said Ricardo Schneider, president and CEO of Danfoss Turbocor Compressors. “This award gives us the unique opportunity to recognize our customers and our organization as a highly integrated partnership that helps bring innovative energy efficiency solutions to the chiller business.”
This is the third AHR Expo Innovation Award that Danfoss Turbocor Compressors has received.
Honorable Mention: ETS Colibri® Electronic Expansion Valve
Recognized as an Honorable Mention in the Cooling category, the new ETS Colibri® electronic expansion valves enable precise evaporator flow control for increased energy efficiency and reliable compressor operation, and are ideal for variable speed air-conditioning and lower-GWP refrigerant systems.
Featuring a hermetically-sealed, smaller, four-times-lighter design that incorporates less complexity with fewer parts and leak points, and 3-to-6-second fully-open-to-close functionality, ETS Colibri® valves offer simple programming and flexible installation, help reduce refrigerant loss, and significantly improve refrigerant migration from reaching the compressor – thus improving reliability and service calls.
“Not only was ETS Colibri® developed for maximum flexibility and dependability and with a compact size that fits almost anywhere into a system, but this new valve is a perfect complement for the transition of air-conditioning, heat pump, and refrigeration systems to variable speed technology,” explained Jeff Warther, North America segment manager for refrigeration and air-conditioning controls, Danfoss. “We’re pleased to have been recognized for the engineering and design innovation that contributed to the development of this new valve.”
The 2015 AHR Expo Innovation Awards recognize the most creative, effective, and ingenious HVACR products and technologies on the market. The annual competition is jointly sponsored by ASHRAE; the Air-Conditioning, Heating, and Refrigeration Institute (AHRI); and the International Exposition Company (IEC), producers and organizers of the AHR Expo. Winners are chosen in each of 10 product categories based on innovation, value, and impact on the market and will be honored at a special ceremony during the 2015 AHR Expo in Chicago.
