Our History

Considering the scientific and experimental activity of over a decade of the board members and the technical opinions of the company and the existence of high potential in the field of executive and technical affairs in the industry of this country, especially the gas industry, at the beginning of 2017, we decided to take action to perform all steps including training, consulting, installation, commissioning, operation and after-sales service of CNG station equipment., by registering HAMIN MEHR Pardis Company. (Training includes: technical courses and operation of CNG stations).

Fortunately, with the efforts of the staff and the board of directors, this company has succeeded in receiving the certificate of integrated quality management system ISO 9001-2015 and ISO 1401-2015 from the international company BRS.

Also, at the beginning of its activity, the regional representative of Havayar Industrial Group, the representative of Asia Petro Gas Service – Delta in the CNG sector) and after that, the company in the list of maintenance companies based on its high potential and capacities. The management of the CNG project and the list of authorized operators of CNG stations has been done by the National Iranian Petroleum Products Distribution Company.

Driving at heights
At higher altitudes, the air is diluted and the engine runs on a richer fuel mix (higher fuel-to-air ratio). As a result, engine power decreases due to reduced engine respiration and less oxygen supply, as well as richer, richer fuel flows. In this case, because the gas engine because the gas is about 12% of the inlet volume and the volume of fuel decreases as the air density decreases due to its dilution, the engine power decreases by 12 to 14%. Therefore, if the vehicle is dual-fuel, it is better to use gasoline fuel at high altitudes
Calorific value
The amount of natural gas energy is about 47 megajoules per kilogram or 40 megajoules per cubic meter, which is a comparison for 60 megajoules per kilogram or 46 megajoules per cubic meter. In other words, one kilogram of gas is equivalent to 1.33 liters of gasoline or 1.22 liters of diesel
Safety
Natural gas is safer than gasoline. Unlike natural gasoline, natural gas is dispersed in the air during accidents and unforeseen events, but gasoline creates pools on the ground that can lead to terrible fires at any moment. Gas storage capsules are also much stronger than gasoline fuel tanks. The design of these capsules is subject to the most severe safety tests such as heat, high pressure, shooting and severe collisions. In general, the risk of fire under normal operating conditions is very low. Due to the fact that CNG gas is lighter than air, it is dispersed in space. But LPG vapor is heavier than air and tends to form pools near the ground
