THE EFFICIENT ENERGY USE
GOGREENinnovative solutions
Today, environmental respect is the core value and guideline to develop new technologies.The environmental sustainability makes its appearance in every sector through researchtechniques for lhe renewal of lhe ræources of our planet Earth.Mankind has the duty to defend and preserve the delicate balance of the Earth,Sustainability for RC Group is the commilment of the presenl generations to leave to futuregenerations the same quantig and quality of resources especially.Since 1997 (from the Kyoto Protocol) to today, the first æpect is the reduction of global
warming, gradually limiting the use of HCFC refrigerants and, later, of F gases as well.
RC Group has embraced and made as ils own lhe eco+ompatibility valuæ, providing
innovative solutions that further than representing the highest possible technological levelare even environmentally friendly.For these reasons, our mission is the study of the effìcient and intelligent energy use, studyunintenupted for more than 50 years.ln fact, RC Group has invented both the first Close Control (1 963) for h24 intensive use andthe first Free-Cooling chiller (1980).The high efficiency of the products together with the study and design of tailored solution,translate into energy savings, and ænsequently in cost reduction.RC Group solutions arise from synergies between RC Group hardware and software,through analysis and energy management.Calculating it in advance and carefully, drive us lo system design compatible withrequirements and environment.At the same time, we can also determine which will be lhe retum of the initial investment in
terms of economies of exercise.
It is thanks to his experience that RC Group has been able to integrate and merge thedesign excellence that distinguishes it for years, with the needs of the environment.The result is a seriæ of solutions arising from the sludy on efficient energy use:

RELIABLEThe Artificial lntelligenæ of RC Group goes green with SPECTRUM, software able to tum asimple technical selection in a projection into the future, by allowing the choice of the mostenvironmentally friendly and more economical solution. Thanks to RC Cloud Platform, the moslmodem form of remote control, the product reliability is always guaranteed.
ECoL0GtCThe focus on the latest regulations in the field of environmental sustainability and energy saving, ledRC Group to adopt reÍigeranb with low environmental impacl, making its products, æ well as
efficient, even tiends of the environmenl
EVOLVEDAlways in step with the conlinuous and rapid technologiæl developments, RC Group uses the bestæmponents and cutting+dge techniquæ and tools, such æ compræsors driven by lnverter andsoftware for the selection and management of the facilities.
NATURALAs pioneer of Free-Cooling technology since the early eighties and still not for everyone, RC Grouphas always plaæd an emphasis on the development of this technique. Anolher system at the baseof energy-saving is the Glycolfree, which allows the use of pure water instead of antifreezesolutions.
