Economic justification of technical audits of cooling systems at plastic products manufacturing enterprises: outcomes of the Rosplast 2025 exhibition

In mid-June 2025, Maxim Sergeevich Talyzin, Editor-in-Chief of the journal “Refrigeration Engineering” and PhD in Engineering, attended the 15th International Exhibition “Rosplast 2025,” dedicated to equipment and materials for plastic products manufacturing. Following the event, this article was prepared to address the economic rationale for conducting technical audits of cooling systems at enterprises employing injection molding. The study analyzes the critical role of chillers as a core component of the production cycle, quantifies the financial impact of their failure, and demonstrates the cost-effectiveness of preventive maintenance. Findings indicate that scheduled audits can prevent up to 90% of unplanned downtimes, reduce scrap rates, enhance energy efficiency, and extend equipment service life by 3–5 years. The economic assessment clearly shows that expenditures on cooling system maintenance yield substantial returns by avoiding potential losses that may reach several million rubles per day.
