In demanding industrial environments, industrial equipment refurbishment goes far beyond simple cleaning. It is part of a comprehensive approach involving refurbishment, modernization, and sustained machine performance. Among the most advanced and environmentally respectful solutions, cryogenic cleaning stands out. Based on the projection of dry ice at high pressure, this technology allows for deep, non-abrasive cleaning without water or chemical residues. Unlike traditional chemical processes, it causes no surface contamination—a critical factor for industries with strict standards such as food processing, aerospace, or electronics manufacturing.
The process is straightforward: solid CO₂ pellets at -78 °C are propelled at high speed onto surfaces. Upon contact, the extreme cold causes impurities and build-ups to fracture and detach without damaging the substrate. Simultaneously, the CO₂ sublimates—transitioning from solid to gas—leaving no residue behind. This is particularly beneficial in refurbishment operations where disassembly and production downtime must be avoided. The absence of moisture also reduces the risk of corrosion or incompatibility with protective coatings.
Preventive maintenance and modernization: a sustainable performance boost
By choosing cryogenic cleaning for preventive maintenance tasks, companies significantly extend the lifespan of their installations. Avoiding the build-up of grease, conductive dust, or organic residues helps maintain optimal performance while reducing the risk of breakdowns. For instance, in the food processing industry, this method is used to eliminate bacterial biofilms from conveyors without affecting protective coatings, ensuring compliance with HACCP standards.
Modernizing production lines also involves mechanical and aesthetic refurbishment. In industrial equipment refurbishment projects, cryogenic cleaning efficiently removes old layers of paint, scale, or industrial adhesives without damaging the underlying surfaces. It is the ideal method for preparing equipment before applying new protective coatings or inspecting welds and internal structures.
A cross-industry solution for diverse industrial needs
Cryogenic cleaning proves effective across a wide range of industrial sectors. In plastic molding, it cleans molds without disassembly, avoiding costly production halts. In pharmaceuticals, it guarantees extreme cleanliness without chemical agents—essential for meeting sterility standards. The metallurgical industry uses it to prepare surfaces prior to coating or during the refurbishment of heavy equipment, including furnaces, turbines, or compressors.
This versatility—combined with speed and the absence of secondary waste—makes cryogenic cleaning a top-tier solution in industrial maintenance plans. It enhances preventive maintenance schedules while supporting the sustainability strategies embraced by a growing number of industrial players.
Environmental optimization and safe intervention
One of the major advantages of this technology is its low environmental impact. No solvents, no liquid discharge, and no hazard to operators or surrounding areas. The CO₂ used is reclaimed from other industrial processes, making it a secondary resource rather than an additional greenhouse gas. This positions cryogenic cleaning as a solution aligned with emissions reduction goals and modern environmental compliance.
By reducing risks associated with chemical products (inhalation, burns, flammability), this method also improves overall safety during operations—especially in confined or elevated areas where other techniques would require more extensive containment measures.
Cryogenic cleaning is not a marginal innovation—it is a direct response to today’s industrial challenges of performance, sustainability, and safety. Whether for industrial equipment refurbishment, modernization, or complete refurbishment projects, it offers a viable and powerful alternative to traditional methods.
