INDUSTRIAL FACILITIES

  • Saving Electricity in Industrial Facilities

Improving the power quality within industrial facilities can have a significant impact on energy efficiency.

There are multiple power quality issues that afflict today’s high-energy consumers including current and voltage harmonics, reactive currents, voltage surges/drops, harmful interactions and flickers. This electrical pollution is caused by the presence of VFDs/inverters attached to most electric motors, DC converters, Soft Starters, Rectifiers, and other power electronics which can be found in most industrial environments. 

Harmonic voltages & currents in particular decrease the efficiency of electrical motors between 5-10%, increase the copper and iron losses of power transformers and reduce their efficiency by approximately 2%.

 

Reduced voltage in the grid also reduces the energy efficiency of electric motors between 7-10%. Moreover, poor power quality increases the thermal losses in cables between 0.5-1.5%. Harmful interactions between the electric loads could lead to a dangerous amplification of the harmonic currents. When all these problems add up within a facility the energy efficiency can dramatically decrease.

SEMAN has completed multiple successful projects across all industries including steel mills, chemicals, refineries, pharmaceuticals, manufactured goods, paper mills and many more.

 

SEMAN’s customized solutions address all the above-mentioned power quality issues and can guarantee a reduction in the overall electricity consumption between 7-13% in industrial facilities.

COMMERCIAL

BUILDINGS

  • Saving Electricity in commercial and residential buildings

Large commercial and residential buildings such as malls, resort hotels, towers, and hospitals can save a lot of money if the power quality issues within their electrical grid are addressed properly. 

SEMAN has years of experience in solving power quality issues and improving the efficiency of the building's heat pumps, elevator motors, air conditioning units, and lighting which can lead to significant electricity savings of up to 13%.

 

SEMAN’s customized interventions can be installed in parallel to the feeding panels of the most important electrical loads within the building and eliminate all the power quality issues at their source, minimizing the harmful interactions between the loads. 

Just like heavy industrial facilities, larger buildings can suffer from the same power quality problems. Harmonic voltages & currents in particular decrease the efficiency of electrical motors between 5-10%, increase the copper and iron losses of power transformers and reduce their efficiency by approximately 2%.

 

Reduced voltage in the grid also reduces the energy efficiency of electric motors by between 7-10%. Moreover, poor power quality increases the thermal losses in cables between 0.5-1.5%. Harmful interactions between the electric loads could lead to the dangerous resonance of the harmonic currents. When all these problems add up within a facility the energy efficiency can dramatically decrease.

SEMAN has achieved significant energy savings in major luxurious resorts hotels, and towers in the urban centers of Europe, North America, and of the Middle east, as well as large hospitals and malls. Our expertise in such facilities allows us to promise significant energy savings results.

CONSTRUCTION​

  • Construction and Design of new electrical facilities with energy saving philosophy 

SEMAN designs and constructs the electrical installation of new industrial and commercial facilities with the energy-saving philosophy in mind.

SEMAN can design and build:

 

  • new substations,

  • low and medium-voltage distribution rooms,

  • transformer rooms,

  • and any other electrical facility according to the local standards and requirements of the clients.

Our experienced electrical engineers and technicians will build your new or retrofitted electrical installation always taking into consideration the power quality issues which are going to afflict this new facility.

Having this knowledge in advance allows SEMAN to design, build and install energy-saving interventions before the facility even starts operating, therefore, building an energy-efficient facility from day one and reducing significantly the construction cost.    

Innovative Power Quality Optimization Methods & Technologies

Our technological advances and carefully designed processes offer a multifaceted cluster of benefits.

Reduces annual electric bills by 7 to 13% year over year (e.g. annual electricity bill of $30 million saves $3 million every year)

Increases power availability by reducing apparent power by 15 to 35% in current electrical installation and power distribution lines – significantly reduces scope and cost of plant expansions

Reduces plant shutdowns and maintenance costs (after 1 year, clients report a 30 to 50% drop in maintenance costs from previous years, and report that unexpected shutdowns occur significantly less frequently)

Reducing vibrations by decreasing the forces inside the equipment from industrial processes, which improves product quality (some clients are able to meet improved quality standards enabling them to sell higher margin products into new markets)

Guaranteed 100% reliability of energy savings and competitive return on investment compared to conventional power-saving approaches

Reduces electrical hazards and improves plant safety
