The G-Range includes all chillers with screw compressors, which are characterized by a simple structure: they are composed of few moving parts which enable a continuous and fluid motion. This leads to the decrease of the mechanical strains, reducing this way the possibility of failure and wear. The simplicity of the engineering ensures a sensible reduction of the vibrations, deriving from the mechanical motions, and of the related noise, with many benefits in terms of comfort and installation.
Thanks to the simple structure of the installed compressors, the G-Range units are characterized by long-lasting life and, therefore, by great reliability, as well as by a significant cut in maintenance costs.
Within the G-Range, we have developed two lines of products, which are distinguished by the type of refrigerant used: the Energymiser line and the Greenmiser line.
Refrigerants
After a comparison with other refrigerants, the R134a turned out to be the best one considering efficiency and financial commitment, as well as installation and maintenance.
On the other hand, the Greenmiser line is characterized by the use of refrigerants with a very low GWP (Global Warming Potential): HFO-1234ze with GWPR290 with GWP=3. Although this kind of systems has experienced relatively recent applications, the Geoclima R&D department has already tested different uses for these refrigerants, with the development of some units for this line of chillers. The main advantages in the use of these refrigerants concern not only the low environmental impact, but also the wide range of possible applications. Especially R290, besides being completely natural, turns out to be particularly suitable for both positive and negative temperature applications. With the Greenmiser line, then, Geoclima is able to provide innovative solutions, aiming at efficiency and eco-sustainability as equally important purposes
All units are tested in a 120 square metres of our factory are dedicated to a fully equipped test center in order to test our chillers by simulating the environmental conditions of the chambers they will be placed in. The new test bench is able to provide a climatically controlled room for air cooled chiller up to a maximum ambient temperature of 52 °C and a minimum of 0 °C.
Since 1994, we have been designing and developing special chillers for applications in air conditioning and refrigeration systems, with particular attention to quality and environmental sustainability. This has helped us to receive prestigious international awards and obtain quality certifications according to the strictest standards.
