Sigma Gostar Arya Engineering Company was established in the year 2008, equipped with the capability and technical knowledge to deploy state-of-the-art industrial automation systems and precision instruments. With a presence in various industries and collaboration with both foreign and domestic companies, the company engages in the implementation of turn-key projects in the following areas.

  • Oil and Gas

Sigma provides services to industries involved in the production, refining, storage, and transportation of hydrocarbons. Sigma has extensive experience in executing projects in multi-vendor environments, complex automation systems, and control of large industrial production facilities. Hydrocarbon processing facilities typically require the integration of various technologies to provide efficient and effective measurement and control. In addition to a central control and monitoring system, these facilities may involve a combination of safety, gathering, SCADA, vibration monitoring, fire and gas monitoring, electrical load monitoring, and measurement systems, as well as analyzers.

Sigma has extensive experience in designing and integrating precision instrument systems, control systems, and related networks and data systems for oil and gas production and processing units. Sigma’s experience in the oil and gas sector includes:

  • Compression and control of pumping stations
  • Measurement and control of wellhead flow
  • Control and monitoring of gas collection systems
  • Gas processing and midstream extraction facilities
  • Gas pressure boosting stations
  • Primary oil separation and refining facilities

Petrochemical and Refining

Complex processes involving potentially hazardous materials are an inherent part of chemical plants. Safety considerations and regulatory requirements necessitate tightly controlled automation strategies and a high level of process design expertise.

Our experience in designing and implementing control systems in the chemical industry enables us to monitor our strategies to ensure that our systems maximize plant safety and operational efficiency. These efficiencies contribute to reduced downtime, increased productivity, and accelerated return on investment in high-capital infrastructure and startup costs.

We offer a wide range of products and systems, including facility automation systems, batch and continuous processes, and many other applications, providing comprehensive solutions for various needs.


 Mines and Metals

In the processes of metals and mining, we go beyond the technical integration skills as we understand the industry’s needs and requirements extend beyond automation technology. We focus on optimizing process performance through the extraction of complex processes in various forms.

We offer a wide range of products and systems, including process equipment, packaging equipment, engineering design, mechanical construction, project execution, batching, HMI software, and many other applications.

Our experience includes:

  • Automated systems for non-destructive testing and mechanical testing.
  • Solutions for Direct Reduced Iron (DRI) plants.
  • Metal melting control systems.
  • Automated systems for material handling.
  • Control and automation solutions for remote monitoring of melting and casting processes.
  • Systems controlling mine ventilation and mine integration.

If your mining and metals project requires automation and integration, we can assure you that with Sigma’s control system, you will achieve the desired results.

Water and Wastewater

Sigma has provided industrial automation services to the water and wastewater industry and has gained significant experience in this sector. Our experience includes large factories, municipal water and wastewater treatment plants, and facilities for the production and distribution of municipal and private water.

Sigma’s experience in water and wastewater encompasses:

  • Control of water and wastewater treatment plants.
  • Pump control for reservoirs and booster stations.
  • Chlorination systems for water treatment.
  • Wastewater lift station and control of wastewater blowdown house.
  • Booster station and remote control of water wells.

If your water and wastewater project requires automation, Sigma can leverage its expertise to ensure effective and efficient control systems tailored to your specific needs.
