Farjad Technology Development Company
Overview of Farjad Engineering and Technology Development Co.
Farjad Engineering and Technology Development Company was established in response to the growing demand of domestic industries for cryogenic plants (oxygen plants) and the need for ongoing technical support in this field, relying on over half a century of managerial experience in industrial sectors.
Key activities of the company include executing EPC projects in the cryogenic sector, as well as manufacturing various types of pressure vessels and portable tanks, such as double-layer carbon CO₂ tanks, ethylene oxide tanks, and aluminum vaporizers.
EPC Projects
Engineering, procurement and construction
EPC Projects are a type of industrial and infrastructure contract that encompass three main phases: Engineering, Procurement, and Construction. In these projects, the contractor is fully responsible for the design, equipment procurement, and construction execution. Upon completion, the project is delivered to the client as a fully operational and ready-to-use facility.
This contract model is especially common in industries such as oil, gas, petrochemicals, power plants, and large-scale infrastructure projects. Due to their high execution speed and reduced risk for the client, EPC contracts are widely favored in complex and large-scale developments.

Air Separation Unit (ASU)
Air Separation Unit (ASU) is an industrial facility designed to separate the various components of atmospheric air—primarily oxygen, nitrogen, and argon. These units play a critical role across a wide range of industries, including steel manufacturing, petrochemicals, medical applications, and electronics.
The most common method used in ASUs is cryogenic distillation, a process that involves cooling air to extremely low temperatures to separate its components based on their different boiling points.
Overview of Farjad Products
At Farjad Technology Development Company, we take pride in being a small yet integral part of Iran’s industrial family. We manufacture and supply a diverse range of products including pressure vessels and cryogenic tanks, turbo expanders, heat exchangers, vaporizers, oxygen valves, molecular sieve vessels, cold boxes, flat-bottom tanks, ethylene oxide tanks, liquefied natural gas (LNG) plants, and cryogenic valves to the market.
Pressure Vessels and Cryogenic Tanks
Pressure vessels are containers designed to hold fluids at internal pressures higher than atmospheric pressure. These vessels are commonly used for storing fluids in both liquid and gas phases.
Cryogenic storage tanks are specialized containers used to store liquefied gases such as oxygen. They are engineered to maintain extremely low temperatures and minimize gas evaporation.
Heat exchanger
A heat exchanger is a technical apparatus designed to transfer heat between two mediums. These mediums have different temperature levels, with one being warmer and the other cooler. Using various methods and structures, the heat exchanger facilitates the transfer of heat from the hot medium to the cold medium. Heat exchangers are widely used across industries such as HVAC, automotive, oil and gas, and many other sectors.
Ambient Air Vaporizer (Vaporizer)
A vaporizer, also known as a heat exchanger, is a gas equipment designed to convert various cryogenic liquids such as liquid nitrogen, liquid oxygen, and liquid argon from their liquid state into gas form.
These heat exchangers operate efficiently through heat exchange with the ambient temperature and do not require any external heat source other than the surrounding environmental temperature.
Flat Bottom Tanks
Flat bottom tanks in cryogenic units are specifically designed for storing liquids such as oxygen, nitrogen, and argon. These tanks feature a double-wall construction, where the inner wall is made of stainless steel and the outer wall is constructed from carbon steel. The space between the two walls is insulated using perlite, providing excellent thermal insulation. Due to their robust design, these tanks are capable of withstanding low temperatures and internal pressure, making them ideal for cryogenic storage applications.
DCA (Direct Contact After Cooler)
DCA is used as a cooling system in cryogenic plants (oxygen plants). This system directly contacts the hot compressed air exiting the compressor with cooling water. The primary purpose of the DCA is to reduce the temperature of the compressed air before it enters the subsequent stages of the process. This temperature reduction enhances efficiency and helps lower energy consumption.
Molecular Sieve Vessels
The Molecular Sieve Vessel in a cryogenic plant (oxygen plant) is used for removing moisture from the gas stream. These vessels contain adsorbent materials such as zeolites, which selectively adsorb small molecules. The operation of these vessels is based on the size and shape of the molecules, allowing smaller molecules to be trapped while larger molecules cannot enter.
Cold box
The Cold Box in Air Separation Units (ASU) serves as a critical component of the system. This equipment is responsible for the separation and distillation of gases at cryogenic temperatures. Typically, the Cold Box includes heat exchangers, coolers, and distillation columns. It is designed to withstand sub-zero temperatures, facilitating the separation of gases such as nitrogen and oxygen within this section.
Turbo Expander
A turbo expander is designed to reduce gas pressure and generate low temperatures. Its operation is based on the principle of gas expansion, converting potential energy into kinetic energy. The incoming gas passes through the turbo expander and, upon expansion, its temperature decreases. This process facilitates the production of liquefied gases such as nitrogen and oxygen. Additionally, the turbo expander can generate mechanical energy, which in some cases is used to power other equipment.
Concrete cooling tower
Cooling towers are used in ASU units to reduce the temperature of water. This device helps in the exchange of heat between hot water and ambient air. Hot water from industrial processes enters the cooling tower where it comes into contact with cold air. This contact causes some of the water to evaporate and lower the temperature. The hot, humid air exits the top of the tower, while the cool water returns to the system.
Liquefied Natural Gas (LNG Plant)
An LNG (Liquefied Natural Gas) plant is an industrial facility designed to convert natural gas into its liquid state. This process typically involves compressing and cooling the gas to temperatures below -160 degrees Celsius. The primary purpose of converting natural gas into LNG is to reduce its volume for easier transportation.
