Sustainability without performance loss: this was the challenge of a large-scale retail player, with many supermarkets in northern Italy, to which MITA supplied several Alchemist adiabatic subcoolers. A solution for increasing performance in refrigeration systems.
One bet that innovation often poses is to move to sustainable technologies without loss of performance. This has also been true for those new installations in commercial refrigeration where MITA Cooling Technologies’ patented adiabatic “subcoolers,” Alchemist series, have been provided.
Arneg Spa, an international leader in the design, manufacture and installation of complete equipment for the retail sector, also took part in the bet, integrating Alchemist to the refrigeration units of some supermarkets in northern Italy.
Precisely in the sector where Arneg Spa operates, challenges dictated by ecological choices are materializing. Among the most important ones is also the transition from the use of high-GWP refrigerants to lower-GWP refrigerants, particularly R744. Thus, there is also a need to remedy the reduction in energy efficiency resulting from the choice to substitute HFC gases (which are generally better performing).
Arneg SpA, according to its corporate mission, aims to “pursue its economic goals while interacting with the environment,” including through new smart technologies. All this is net of some special requirements: Arneg’s supermarket customers, for example, may be located near residential centers and thus require low-noise solutions.
Alchemist was conceived by MITA Cooling Technologies (a company that has been designing, manufacturing, and marketing evaporative and adiabatic coolers and condensers since 1960) specifically for commercial refrigeration with R744 systems, a particularly demanding sector that is attentive to both consumption and reliability.
The standard version of Alchemist adopts low-noise EC PLUG-FAN fans; in one of the installed machines (5000 S version), sound-absorbing paneling was also provided to further reduce noise impact.
The use of Alchemist has proven to be optimal in terms of increased performance, while also containing sound levels: the adiabatically treated air (i.e., at a lower temperature than ambient air) goes to “subcool” the refrigerant in the refrigerant circuit. This action leads to an increase in the useful effect and consequently greater efficiency of the refrigeration cycle, which translates into electricity savings.

Supermarkets and large-scale distribution are increasingly attentive to environmental sustainability: hence the choice to use natural refrigerants for chillers. In these cases, the adiabatic subcooler patented by MITA guarantees an extra step in efficiency: a solution that can be easily integrated into the system.
Refrigeration in the food sector is linked to production lines in food & beverage: the optimization of efficiency and resources (water and energy) are the most requested needs by customers. Evaporative and adiabatic condensers must be able to manage different refrigerant gases based on project requirements.
Foodstuff storage at temperatures below zero can be implemented through different types of natural or non-natural refrigerants: evaporative or adiabatic condensers can be indicated, depending on whether the company is focused on performance or resource use optimization. Low noise solutions are often appreciated.
Langhe, a historic area of Piedmont known for its wines and haute cuisine. MITA Cooling Technologies participated in the modernization of a dairy's refrigeration system with two heterogeneous solutions: the MCE evaporative condenser and an adiabatic condenser.

One of the most advanced poles for the study of power grids in Europe, in Sardinia, also bears the signature of MITA Cooling Technologies: this is thanks to 13 adiabatic coolers supplied to Ansaldo, among the main implementers of the work.
