     • cell type, with a side door;
     • shaft type, with a lid on top – for large and heavy products that shall be loaded using lifting equipment;
   • size of chambers from Ø600×600 mm (~200 l) to Ø1200×1400 mm (~1600 l);
   • made of stainless low gasing steel;
   • have water cooling system;
   • have a heating system with hot water to prevent water vapor condensation and outgassing of the chamber walls during opening of the chamber and pumping out.

2. Water cooling and plant unit heating systems.
   • types of systems:
   • with open drainage – open “funnel”;
   • closed drainage for loopback self-contained cooling systems with water circulation pumps;
   • have stand-alone automated system for water heating for heating of chamber walls and other units;
   • have alarm systems of water flow presence in individual channels and the emergency stop of respective devices.

3. Product rotation mechanisms.
   Types of rotation mechanisms:
   • planetary – simultaneous rotation of products around their own axes and around the axis of the chamber;
   • double planetary – rotation around its own axis, around satellite axis and around the chamber axis;
   • mechanism for rotation in two perpendicular or inclined planes.

4. Vacuum system:
   • provides:
     • residual vacuum at 10^-5mm Hg;
     • duration of pumping out from working chamber to maximum vacuum for no longer than 12-15 minutes;
   • is based on the highly efficient diffusion pump and mechanical rotary vane and two-rotor pumps;
   • for specific requirements to the vacuum it is produced on the basis of turbomolecular, adsorption, and other pumps.

5. Gas supply system:
   • consists of:
     • control unit on the basis of high-flow gas flow meters and pulse inlet valves;
     • programmable electronic control unit.
   • provides supply of a mixture of working gases into the chamber with control and automatic maintenance of:
     • ratio of gases in the mixture;
     • pressure in the chamber.
   • displays the values:
     • percentage of gases in the mixture;
     • running costs of different gases;
     • pressure in the chamber.

6. Plasma sources.
   Plants are equipped with:
   • Electric arc plasma sources with separation of flow SPS-1, providing:
     • coating speed of up to 40 micron/h;
     • surface etching speed up to 10 micron/h;
   • direct flow ram electric arc plasma sources (evaporators);
   • electric arc sources with two-step discharge for ion treatment of products;
   • sources of metal ions with energies up to 100 keV (implanters) – for ion implantation.
     Plants can also be equipped with sources of ions, plasma, and other devices developed by other companies– our partners.
