DEMZ has an engineering and R&D infrastructure continuously expanded and enhanced by new developments from the plant’s engineers, as well as joint projects with specialized design bureaus and research institutes. DEMZ features modern production facilities equipped with advanced machinery, a finished goods warehouse, office spaces, and auxiliary premises. All work is performed exclusively by qualified specialists, ensuring top product and service quality.
DEMZ collaborates with leading industrial machinery manufacturers in Germany, Bulgaria, Italy, Poland, Finland, and Slovakia. A proud milestone in our international cooperation is partnering with an investment industrial group from the United Kingdom to create a joint innovative premium-class product.
DEMZ offers high product quality and comprehensive customer service as our primary competitive advantage. This is proven by equipment deliveries abroad — to power plants in Mexico, Panama, Nicaragua, and India, as well as mining enterprises in Armenia, Hungary, Kazakhstan, and South Africa. Companies in Germany and Finland are regular consumers of our special steel structures.
DEMZ does not focus exclusively on mass production of standardized goods; alongside serial production, we manufacture equipment tailor-made to the Customer’s Technical Specifications. Because our products are developed with the specific demands of our most exacting clients in mind, we can fulfill your unique requirements.
DEMZ supplies products and services under the DEMZ® trademark to ports, mining, metallurgical, and machine-building enterprises in Ukraine, as well as major industrial groups (ArcelorMittal Kryvyi Rih, Interpipe, Ferrexpo, Privat, SCM, DCH, and others).
By choosing products under our trademarks, you get quality, reliable service, and a dependable partner.
We invite you to a long-term cooperation.
Sincerely, Director, “Dniprovsky Energomechanical Plant”

Frequently Asked Questions (FAQ)
The lifting capacity of an electromagnet is the maximum load weight permitted to be lifted and moved by the magnet. It typically equals 0.5 of the breakaway (tear-off) force, providing a safety factor for secure operation.
The lifting capacity depends on the magnitude of the magnetic flux in the core. The flux increases as the magnetomotive force increases and as the magnetic reluctance of the circuit decreases.
Copper coils cost twice as much as aluminum ones; copper has 1.7 times higher conductivity than aluminum; copper density is 3.3 times higher than aluminum; copper’s specific heat capacity is 3 times lower than aluminum’s; copper coils offer more repair cycles and a longer service life than aluminum.
Welded steel housings are simple and cost-effective to produce. The advantages of a cast magnetic core over a welded one include cooling fins, greater operational durability, solid structural integrity, and the complete absence of internal air gaps.
Overheating, lower density of scrap metal, switching to metal stock with larger air gaps, and malfunctions in the control cabinet (voltage converter).
Improper operation (faulty control cabinet, overheating, moisture exposure, overvoltage), coil-to-housing breakdown (ground fault), open-circuit/broken conductors, and inter-turn short circuits within the coil.
