The ELN-2 unit is designed to implement the technological process of high-temperature soldering of products such as heat exchangers with electron beam heating.

The ELN-2 unit includes the following main units:

- vacuum chamber;
- in-chamber product manipulator;
- power complex;
- vacuum system;
- automated control system;
- system for distributing electron beam power over an area;
- remote temperature field monitoring system;
- unit maintenance platform;
- compressed air supply system;
- auxiliary control and measuring
- technological equipment and tooling.

The working chamber of the ELN-2 unit is designed to create a vacuum environment in the area of soldering parts with an electron beam, taking into account gas emissions during soldering. The chamber has portholes for visual observation and installation of control and measuring devices, with protection against sputtering and overheating.
The intra-chamber movement module is designed for loading into the chamber, fixing on the faceplate and moving the products. The module ensures the positioning of products for soldering and consists of mechanisms for longitudinal, transverse, vertical movement and rotation of the product.

Control system.
The "ELN-2" control system ensures the following functions:
3-axis positioning of the product during the technological process;
software control of energy characteristics;
the ability to register process parameters and archive results.

The control system ensures the registration and recording in the archive of the values of the electron beam welding technological process parameters: contour speed - welding speed, pressure in the working chamber, welding current, focusing current.
Interlocks ensure safe operation of personnel, protection of the unit units from erroneous operator actions, blocking of mechanical movements and power supply shutdown in emergency situations, the most favorable completion of operation in case of detected deviations in the equipment condition.
The soldering process is controlled through the operator's human-machine interface.
