Energy Saving by "VSD System"

Havasazan Tabriz achieved energy saving products by focusing on the knowledge and modern technologies that are reducing costs for the industrial units; finally we attempt to present a new rotation control system (inverter) that called “VSD” with especial application on our industrial compressors. This system can be installed in two methods on the manufactured “oil injected compressors”:

Integrated Installation on the electrical panel of compressor

Separated Installation on the Independent electrical panel

Cost Saving with energy saving:

For compressed air system, electrical costs allocate largest expenditures to itself. For example, the initial cost for purchasing a compressor with 100 HP (75 kW) is between 20-25 thousand dollars (depends on the compressors type and manufacturer); whereas, the annual electrical costs may be increase to 10 thousand dollars. Further more, maintaining costs may be 10% or more than 10% of initial purchasing cost annually.

Calculations show annual electrical expenses for 75 kW screw compressor which is working 12 hours daily, with 70% under load and 30% without loads, considering the minimum energy tariff can be takes 11 thousand dollars, but it can be saved economically by VSD energy saving system via its average efficiency (35%); the result is 3.7 thousand dollars saved for electrical costs.

Considering the minimum costs of energy and project costs containing maintenance, spare parts and overhaul, the return of investment in VSD system is less than 18 months.

VSD system can be installed in all TORNADO models (15-400 KW). Meanwhile, all spare parts, servicing and warranty are providing by Havasazan Tabriz.

Some advantages of VSD system:   

 

  1.  Energy saving up to 20-40%

  2.  Increasing the efficiency and lifelong of the machine due to its intelligent performance and reducing mechanical or electrical impacts.

  3. Decreasing maintaining service and space parts expenditures with preventing frequent “Loads” and “Unloads”.

  4. Changing the degree of flow or air pressure through changing the voltage and frequency of electromotor; As a result, saving energy and decreasing  any metal, copper, electromotor rotation and Air End wastes.

  5. No need to “pulley” for change or increase the pressure band.

  6.  Being safe against any overload, increase/decrease of voltage, over currency, phase shift, earth leakage fault, high-temperature and etc.

  7.  Ability to decrease compressor electrical current and utilization of electrical equipment (such as contactor, switch, fuse, cable and etc.) with the lowest potential.

  8. Decreasing any environmental pollutants in fluid flow handling process, alongside saving energy and economic consequences.

  9.  Preventing any electrical current leakage in the compressor equipment.

  10.  No need for any compensation capacitor (capacitor bank), due to the input capacitor of the VSD.

  11.  Preventing any mechanical damage such as couplings, gear-boxes and belts, due to “Soft Start” and variable rotation.

  12. Increasing considerably range of rotation changes rather than varied mechanical methods and preventing any mechanical tensions and vibrations.

  13. No need to contactor for changing electromotor rotational direction.

  14.  No need to main power for turning on/off the electromotor.

  15.  Automatically “off” during any overload and displaying “overload message” to the users.

  16.   No need to any extra maintenance rather than fixed-speed compressors.

PSA Nitrogen generators:

Pressure swing adsorption.

In the PSA process, compressed air first passes through a combination of filters to remove entrained oil and water. The purified air is then directed to one of two adsorption vessels that are packed with carbon molecular sieves (CMS). The remaining impurities, such as carbon dioxide and residual moisture, are adsorbed by the CMS at the entrance of the adsorbent bed. At high pressure, the CMS selectively adsorbs oxygen, allowing nitrogen to pass through at the desired purity level. While one vessel is producing nitrogen, the second vessel is depressurized to remove the adsorbed oxygen, which is then vented to the atmosphere. The automatic cycling of adsorption and desorption between the two beds enables the continuous production of nitrogen.

A large range of flow and purity combinations can be met by adjusting the size of the air compressor and adsorption vessels containing the CMS. PSAs can economically produce nitrogen gas at flowrates from less than 5,000 scfh to greater than 60,000 scfh, and at purities ranging from 95% to 99.9995%.

Blowers are industrial machines which are applying to manufacture high flow air volume with minimum 2 bars pressure for industrial usages.There are different kinds of Blower which are categorized regarding air flow and pressure.These days Turbo Blowers, as new generation of Blowers, which are highly noticed by industries as water and drain refineries, food industries, petrochemical and 

In Turbo blowers as Turbo compressors the main part is Impeller which benefits of high technology.The main motive of Blower motor is permanent magnetic motor. The efficiency of these motors in high speed is more than other custom motors and the functions of these motors are adjustable by inverter (VSD) system.Applying Airfoil bearings caused the function of machine be independent of oil and be without vibration and ruining; therefore the parts lifetime are increased and the maintenance costs are minimized

Energy saving in Turbo Blower in comparison with the common Blower leads to -50% of the costs.The high technology of these Blowers leads the capital return during 2-3 years.

Centrifugal compressors are new high technological method to supply compressed air in all fields of industries. In this kind of compressors, kinetic energy of air is increased by means of impellers and then, this energy is converted to potential energy of pressure in plenum chamber. Also, because of no use of oil in compression process in centrifugal compressors, this technology is very attractive for oil and gas, petrochemical, steel, pharmacy, cement, textile and … industries. Capacity can be controlled by adjusting the inlet guide vanes— closed to reduce and open to increase flow. Centrifugal compressors feature a simple, effective design that outperforms other compressors in delivering trouble-free operation and the lowest cost of ownership. Owners enjoy:

• Low maintenance with no wearing parts that require regular change-out. Eliminates the need for periodic and expensive air end replacement.

• Low-to-no vibration without any special foundation required.

• Superior control through a variety of Regular controller system options.

• Excellent reliability over extended periods with minimal maintenance.

• High durability (more than 8000 hrs) from run time to first maintenance.
