Introduction

Energy efficiency of Ukrainian industrial enterprises is a critical factor in their competitiveness. Current standards and rising electricity costs require a review of approaches to the operation of power units and pneumatic systems. Outdated equipment of classes IE1 and IE2, as well as worn pneumatic distributors, consume excessive amounts of energy and have a high risk of sudden failures. Modernization of the electric motor fleet to classes IE4 (Super Premium) or IE5 (Ultra Premium) in combination with updating the control pneumatic systems ensures significant reduction of operating costs.

The main argument of conservative engineers — "old equipment still works" — is refuted by a simple calculation of total cost of ownership (TCO). Energy costs over 3-5 years significantly exceed the initial cost of a new drive. UNITEC-D GmbH supplies CE and UkrSEPRO certified electric motors and control components, including modern fast-acting pneumatic distributors such as Festo MYH-5/2-M5-L-LED, for industrial enterprises in Ukraine.

Evaluation of obsolete systems

Before starting the modernization, a full audit of the current state of the equipment is required. Special attention is given to engines with service life over 15 years and pneumatic lines with high levels of compressed air leaks. Below are the criteria for assessing obsolete components:

Modern Alternatives: Technology Comparison

Transition to new energy efficiency standards according to DSTU IEC 60034-30-1 and EN 50598 requires a clear understanding of the technical differences between generations of equipment.

In the field of pneumatics, similar efficiency jumps are demonstrated by modern micro distributors. For example, replacing old heavy pneumatic valves with a modern modular block featuring elements such as Festo MYH-5/2-M5-L-LED reduces response time to units of milliseconds, lowers consumption of control air and provides visual indication of the status thanks to integrated light-emitting diodes (LED).

Detailed ROI Calculation

Let's consider a real example of modernization of a 11 kW drive on a Ukrainian cement plant (or heavy machinery manufacturing enterprise). Calculation conditions:

• Power of the engine: 11 kW
• Working mode: 3 shifts, 6500 hours per year
• Cost of electricity for industry: 6.5 грн/кВт·год (including transmission and distribution)
• Efficiency of old motor (IE2): 89.2%
• Efficiency of the new motor (IE4): 94.1%

Power consumption of the old engine under 80% load (8.8 kW on the shaft):

Power consumption of the new IE4 motor:

Power saving per hour:

Annual electricity savings:

Financial saving per year:

If the savings from eliminating unplanned downtime (average cost per hour of downtime for a conveyor line — 45 000 UAH) and reducing compressed air leaks through updating the distribution equipment (Festo MYH-5/2-M5-L-LED), the overall payback period for the package of measures ranges from 8 to 14 months.

Implementation Roadmap

1. Audit and Design (Weeks 1-2): Instrumental measurement of real engine load, analysis of power quality, pneumatic system audit.
2. Selection and procurement (Weeks 3-4): Order of motors of the appropriate size according to the IEC standard, selection of associated valves and electronic components through UNITEC-D E-Catalog.
3. Preparatory works (Weeks 5-6): Inspection of mounting positions, replacement of worn couplings, preparation of cable routes and updating of pneumatic lines.
4. Installation and commissioning (Weeks 7-8): Removal of old units, installation of IE4/IE5 motors, calibration of frequency converter parameters, testing of pneumatics.

Technical Problems and Ways of Their Resolution

During engine replacement, engineers often encounter the problem of mismatched mounting dimensions between old Soviet series (for example, 4A or AИР) and modern European IEC standards. The solution to this problem is the use of certified adapter plates or ordering engines with special mounting designs (IM B3/B5). The second common problem is high starting currents of permanent magnet synchronous motors. This is resolved by mandatory use of modern vector frequency converters with support for smooth start.

Case Study: Modernization of Pump Station Drive

At a food industry enterprise in Dnipro region, three pump units with IE1 motors were replaced with IE4 class motors and the control pneumatic system was updated.

• Показник MTBF: Зріс з 12 000 годин до 45 000 годин.
• Electricity consumption: Decreased by 11.4% year-on-year.
• Noise level: Reduced by 4 dB(A) thanks to precise rotor balancing and high-quality bearing units.

Receiving and Validation

After completion of the installation works, mandatory tests are carried out according to ISO 10816 (vibration control) and ISO 50001 (energy efficiency verification). Documentation is prepared in accordance with the requirements of Ukraine's technical regulations on the safety of low-voltage equipment and machinery.

Conclusion

Modernization of outdated equipment by switching to IE4/IE5 motors and modern automation components is a necessary investment for stable operation of an industrial enterprise. For selection of required spare parts and consultations, contact technical specialists and use UNITEC-D E-Catalog.

Calculation of return on investment

Energy savings, reduced repair costs and reduced downtime are important to calculate return on investment (ROI).

An example of a calculation for an engine with a power of 11.5 kW:

• Annual energy: 11.5 kW * 2000 hours = 23,000 kWh
• Energy savings: 11.5 - 9.2 = 2.3 kW
• Annual savings: 2.3 kW * 2000 hours * 0.22 UAH/kWh = 1012 UAH
• Implementation cost: UAH 18,500
• Investment return period: 18,500 / 1012 ≈ 18.2 months

In addition, a reduction of downtime by 50 hours per year corresponds to savings of UAH 1,000 per year. This adds to the total savings of UAH 10,000 per year.
