ALIGNMENT of a gas generator at a paper factory

At a paper manufacturing plant located in the village of Chaltyr, work on the alignment of a gas generator with a power of 1200 kW was successfully completed. This gas generator is a key element of the production line, so its precise installation and alignment are extremely important for ensuring the efficiency of all equipment. In the process, specialists precisely adjusted the position of the generator horizontally, vertically, and by angle. Thanks to the high qualification of our specialists and the use of modern equipment, the accuracy of alignment was 0.01 mm. Such high precision ensures perfect interaction of all elements of the mechanism and guarantees uninterrupted and efficient operation of the gas generator.

EXPANSION OF CONVEYORS AT LARTA GLASS ROSTOV PLANT

Fifty-eight conveyors have been modified to transport 9m glass. Before the modification, the factory produced base glass with a size of 6m. The well-coordinated work of designers, mechanics, programmers, designers, assembly teams allowed us to reformat production and rebuild the production line to produce new glass sizes in a short time.

As a result of cooperation and successful interaction between the two companies, the first batch of 9.3 m glass was produced and presented at the MosBuild 2023 exhibition. 

On March 30, at the MosBuild 2023 exhibition, the winners of the MosBuild Awards were awarded. This award annually recognizes the best new products and solutions for the building and interior industry. In the Facades and Roofing nomination, the winner was LARTA GLASS and its new product, oversized glass, created using a technology unique to the Russian market. Until recently, such glass could only be ordered from Europe and China. And now architectural glass with energy-efficient magnetron sputtering LartaPro 9.3 meters long LARTA GLASS began to be produced at a plant in the Rostov region.

Cryogenic gasifier for trout fishery in the village of Ardon, North Ossetia

The installation of a cryogenic oxygen gasifier has been successfully completed in the village of Ardon. This complex equipment, equipped with a flow meter and pressure regulator, is designed to saturate the water in trout ponds with oxygen, which ensures more efficient fish farming. During the installation, X-ray control of the welded seams was carried out, guaranteeing high-quality work and reliability of the structure. After the completion of the work, a complete set of execution documentation was prepared, as well as a set of documentation for submission to the Rostekhnadzor authorities. This project is an important step in the development of aquaculture in the region.

OXYGEN COMBUSTION SYSTEM FOR LARTA GLASS ROSTOV GLASS FURNACE

We have successfully installed two cryogenic tanks and evaporators, which are key components of the OxyBoosting oxygen combustion system for the glass furnace of Larta Glass Rostov. The OxyBoosting system uses oxygen instead of air in burners, which allows for a higher combustion temperature and thus increases the efficiency of the glass melting process. This also leads to a reduction in CO2 and NOx emissions, making the process more environmentally friendly. Thanks to the increased energy efficiency of the gas burners, we were able to improve the quality and volume of glass production, which ultimately led to an improvement in the overall performance and efficiency of production at Larta Glass Rostov.

LIQUID NITROGEN DISPENSING AND DOSING SYSTEM FOR DANONE YOGHURT PRODUCTION LINE

A modification and adjustment were carried out under low pressure on a group of cryogenic cylinders for droplet dosing of liquid nitrogen into yogurt bottles. This innovative approach allows for the optimization of the nitrogen dosing process, ensuring more accurate and efficient use of resources. The automated nitrogen delivery system allows for control and adjustment of the amount of nitrogen supplied, ensuring accuracy and consistency in the process. Moreover, the system increases the stability of maintaining pressure in the dosing complex, which in turn contributes to improving the overall efficiency and reliability of the production process.

STRAIGHTENING COLUMN FOR THE PRODUCTION OF MOLASS

Work on the piping, software development, and commissioning of a rectification column for molasses production has been successfully completed. The piping of the column included the connection of all necessary pipes and safety devices. The developed control program allowed the distillation process to be automated. After all checks and tests, the column was successfully launched and began producing molasses.

AUTOMATION AND COMMISSIONING OF A HIGHLY LOADED FLYING CRANE WITH A CAPACITY OF 400 TN
