# Efficient and Sustainable Cleaning: A Comparative Analysis of Cryogenic Technology
## 3 Results  
### Data Collection  
The equipment selected for the evaluation of the efficiency and sustainability of dry ice blasting systems (see Tables 2 and 3) reflects different performance and formal characteristics. It presents hybrid and single-functional equipment designed for solid and liquid CO\({}_{2}\) spraying. The collected data encompass specific criteria such as dimensions, power supply, air pressure, air volume flow rate, sound pressure level, tank capacity, pellet diameter range, carbon dioxide consumption, and weight of the equipment without accessories. \begin{table}

The Polartech(r), Intelblast(r), and Cryoblaster(r) brands showed similar dry ice consumption, ranging between 20 and 90 kg/h, suggesting comparable efficiency in resource management. In contrast, equipment from Karcher(r) and Cold Jet(r) exhibited higher consumption, ranging from 30 to 120 kg/h and less than 108 kg/h, respectively. This could be reflected in higher operating costs. This factor is crucial, especially in large-scale operations where dry ice consumption is a significant variable in the cost structure. The pellet size used by dry ice blasting equipment generally tends to use smaller diameter pellets, equal to or smaller than 3 mm. This size is shown to be consistent across several models, such as the Karcher(r) IB 15/120, the Karcher(r) IB 7/40 Adv, and the Intelblast(r) IBL 3000. The ability to vary pellet size can significantly influence cleaning efficiency depending on the specific application and surface to be treated. The size and weight of the equipment also play an important role, especially in terms of logistics and storage. The Karcher(r) and Cold Jet(r) equipment is heavier and larger, potentially increasing transport and storage costs, while the mini versions of Polartech(r), Intelblast(r), and Cryoblaster(r) offer greater practicality. Polartech(r)'s compact model, with dimensions of 410 \(\times\) 470 \(\times\) 480 mm and a weight of only 26 kg, stands out in this respect, offering significant advantages in terms of manoeuvrability and storage space. On the other hand, neither the pressure nor the amount of ice projected is adjustable [50]. The tank capacity of dry ice blasting equipment plays a crucial role in the operational efficiency and duration of blasting sessions.
