A domestic knowledge-based company has developed a device that can help monitor air quality online by collecting related data.
The device uses 16 sensors to measure parameters such as PM2.5 (particulate matter with a diameter of 2.5 micrometers) and SOx (sulfur oxides). Exposure to high levels of these gases can cause serious health issues.
Saman Abargan Water Company also handles the installation, calibration, maintenance, repair and supply of parts of the air monitoring device, the news portal of the Vice-Presidency for Science and Technology reported.
Currently, about 100 locations in Iran use air quality measurement devices to monitor the ambient air online. These devices consist of analyzers, service tools, sampling pipes and data loggers.
The company offers two-year warranty for replacement of parts and free service for all its products, which are not extended for foreign counterparts in Iran.
In addition to its accuracy and sustainability, the main advantages of the domestic device include its compatibility with climatic conditions, cheaper price compared to foreign models, prompt customer support and abundant supply of parts.
The company has also developed a software to provide domestic online monitoring services. By using the software, all the ambient information can be accessed remotely.
The software helps users identify the source of environmental pollution, which are mainly industries and vehicles, and monitor air pollution information constantly. The information obtained by this device is used to control environmental pollution.
Anti-Hail System Developed
A domestic knowledge-based company has designed an anti-hail system that can convert hail into rain to prevent damage to trees and facilities during hailstorms.
The system can liquefy the hail through a special process before they reach the ground.
“The anti-hail system turns the hail into raindrops by producing special sound waves in the sky,” Alireza Nourian, the CEO of Ervin Hail Industries Company, was quoted as saying by the news portal of the Vice-Presidency for Science and Technology.
He pointed out that the most important advantage of the domestic anti-hail system is the ability to prevent any potential damage during a hailstorm.
The system creates a series of acetylene gas explosions in a special reactor, which gives rise to sound waves with a special frequency. It then directs sound waves into thunderclouds. The waves disturb the formation of hails by creating turbulence in ice crystals, which turn hailstones into raindrops.
The anti-hail system can be used to protect crops, gardens, urban areas, industrial sites, car companies’ parking lots and any open warehouse where goods, products, or equipment need protection during a hailstorm.
The director of the knowledge-based company explained that the domestic anti-hail system is 30% more effective and cheaper than its foreign counterparts.
“The system has been designed in two forms. One is a semi-intelligent system that is designed for the first time in the Middle East and the second model is the first smart system designed in the world,” he said.
The domestic anti-hail system has met the needs of the country for anti-hail systems and prevented forex outflow. So far, 500 anti-hail systems have been installed in the country.
The system has been exported to Turkey and its quality has satisfied foreign customers.
Nourian noted that the design and development of the anti-hail system have created a large number of direct jobs and 20 indirect jobs.
Flame Monitoring System Rivals Foreign Models
Another domestic company has developed a flame monitoring system that controls the flame in equipment such as power plant turbines, where the continuity of the flame is vital.
“Typically, a flame monitoring system consists of one or more sensors and a trigger. The function of the starter or amplifier is to receive a signal from the flame detector sensor and announce its status," Mehdi Arianfard, a member of the board of directors of Sang Chin Zahedan Company, said.
Gas turbine is one of the most important equipment in oil, gas and energy industries. The important task of monitoring and evaluating its efficient performance is handled by the flame monitoring system.
The color of the flame varies from infrared to ultraviolet, depending on the type of fuel used. As the fuel used by turbines is natural gas, its flame has more ultraviolet components.
With the production of this domestic practical system, there is no need for foreign counterparts.
“South Pars Gas Company has replaced a foreign system with a domestic one for monitoring gas turbines,” he added.
In addition to turbines, the flame monitoring system is also used in furnaces.
“Currently, we can meet the country’s demand without the need for imports. The domestic system has prevented a large amount of capital outflow,” Arianfard said.
“While matching the quality of foreign models, it has been marketed at a lower price. It costs more than $2 million a year to import foreign counterparts.”
