Introduction: The need for modernization
Compressed air systems in Ukrainian production often remain backward, which leads to a loss of efficiency, an increase in energy costs and corresponding regulatory requirements. According to the EC Ecodesign directive for energy-efficient devices, production systems must meet the requirements of energy consumption, which requires modernization. This article examines a practical strategy for upgrading compressed air systems using high performance components compliant with DSTU, EN and ISO standards.
Evaluation of old systems before upgrading
Before starting the update, it is necessary to evaluate the current state of the system. The main evaluation criteria are listed below:
| Criterion | Assessment | Standard |
|---|---|---|
| Efficiency of energy consumption | 30-40% losses | EN 12723:2011 |
| Frequency of failure | 200-300 hours | ISO 15316:2017 |
| Energy consumption | 120-150 kW | IEC 60034-1 |
| Air flow | 10-15% losses | DSTU 3013:2016 |
Modern alternatives
Compressed air system upgrades can include the use of highly efficient variable frequency drive (VSD) compressors, diagnostic flow detection systems and intelligent piping. Below is a comparison of old and new technologies:
| Indicator | Old compressor | Modern compressor (Parker DSMN212-P25E10-PBF) |
|---|---|---|
| Efficiency of energy consumption | 70% | 92% |
| Frequency of failure | 200-300 hours | 500-700 hours |
| Energy consumption | 120 kW | 85 kW |
| Air flow | 10-15% | 2-5% |
| The cost of the set | €25,000 | €35,000 |
Calculation of return on investment
Return on investment (ROI) calculations include energy savings, reduced repair costs, and reduced downtime. Below is an example of a calculation:
The cost of the upgrade: €35,000
Energy savings: €35,000/year
Reduced repair costs: €12,000/year
Reduced time loss: €4,000/year
Annual benefit: €51,000
Payback period: 0.68 years
These figures show that the investment in upgrading the compressed air system is worthwhile in terms of savings.
Implementation plan
The upgrade of the compressed air system should be done in phases to minimize production stoppages:
- Planning: Determination of needs, evaluation of the system, selection of components.
- Order: Receive components from UNITEC-D, including Parker DSMN212-P25E10-PBF.
- Installation: Replacement of old components with new ones, installation of intelligent pipelines.
- Preparation: System testing, debugging, performance evaluation.
This approach ensures continuity of production and efficient use of resources.
Technical challenges
During the upgrade, problems may arise, such as compliance of old components with new standards, the need to modernize pipelines and solve problems with energy consumption. To solve them:
- Use components conforming to DSTU, EN and ISO standards.
- Carry out regular energy audits.
- Use intelligent monitoring systems to detect currents.
United-D provides components that meet all requirements, ensuring reliability and efficiency.
Case stage: After upgrade
The compressed air system was updated at the Dnipropetrovsk factory. After installing the new components:
- Energy efficiency increased from 70% to 92%.
- The frequency of failure has increased from 200-300 hours to 500-700 hours.
- Energy consumption decreased by €35,000/year.
- Airflow was reduced by 10-15%, which reduced repair costs.
These results demonstrate the effectiveness of upgrading compressed air systems.
Preparation and confirmation
After installing the new components, the following procedures must be performed:
- Testing: Checking the efficiency of energy consumption, currents and stability of the system.
- Acceptance: Compliance with DSTU, EN and ISO standards.
- Documentation: Storage of certificates and energy audits.
These steps ensure system reliability and compliance.
Conclusion
Renewal of compressed air systems is an important stage of production modernization. The use of high-efficiency components such as the Parker DSMN212-P25E10-PBF provides significant economic and energy benefits. You can get all the necessary components in the UNITEC-D E-Catalog.
