Server rooms from R&P enterprise "Stealth"
Since 1997 the research and production enterprise "Stealth" is specialized in a protective shielding of server rooms, manufacture of load-carrying metal structures, inspection and flaw detection of welded joints and anti-corrosion protection of metal structures. Many works are fulfilled by us in collaboration with specialists of the E.O.Paton Electric Welding Institute of the NAS of Ukraine, the recognized leader in the field of electric welding and quality control of the welded joints.
The National Bank of Ukraine has issued several Resolutions, directed to guarantee the steady operation of the bank system and made all the banks and their branches to equip the server rooms with electromagnetic shields (Resolutions of NBU Board No. 243 of 04.07.07).
Over the recent years our specialists have made more than 50 shielded rooms, whose technical requirements exceeded more often the standard requirements both as to the signal attenuation and also to the frequency range of the shielding. Thus, for example, the shielded structures were designed, manufactured and mounted on the objects being protected, guaranteeing the following parameters:
- electromagnetic attenuation in the range of 100 kHz – 1 GHz is not lower than 72 dB;
- shielded system of a continuous electric supply of 15 kW power;
- shielded system of heat dissipation and ventilation for 216 kcal/min;
- equally shielded system of electromagnetic locking, fire signalization and control of access.
R&P enterprise "Stealth" carries out constantly the applied research works, development of the new products. Over many years our specialists present papers at scientific-practical conferences on technical protection of information, on the progress in bank technologies.
Our specialists have designed an assembled-disassembled shielded cabin. The cabin design allows flexible selection of required sizes, realization of its mounting in the room without welding application, and, when necessary, its disassembly and transportation to another object. Moreover, the cabin is in a full compliance by its shielding properties with requirements of standard documents and close to the all-welded shielded rooms, and the technical specifications for it are coordinated with DSTSZI SBU (TS U 28.1-22897309.001-2002) for the use of cabin as a means of Technical Protection of Information (TPI). Such cabins have been already mounted by us and operate successfully at 10 objects including those in operating server objects.
Our specialists have also developed the designs of a shielded strong box (safe) for storage of magnetic carriers, which is designed for protection of carriers from breaking in, non-sanctioned access, electromagnetic action, moisture, fire.
A shielded cabinet for 1-3 servers has also been designed. The cabinet represents a mini server room and can be transported to the objects in as-assembled and certified form.
Our experience and knowledge allows realization of all the specialized works at high quality and technical level.

"Krok" LLC is a manufacturer and supplier of various facilities to measure: mass, pressure, temperature, level, expense, laboratory and manufacturing equipment of leading world manufacturers.

More than a half of known technologies, including metallurgy, foundry, ceramics and glass production, chemical and food industries are based on thermal action on raw and auxiliary materials. In mentioned technologies temperature is the principal parameter determining production quality and expenses for it manufacturing, e.g. expenses for power, fuel, materials, springing of thermotechnical equipment, etc. Leading world-known companies connect main successes in production quality rising and decreasing of resources consumption with new achievements in the field of temperature monitoring and optimal control of thermal technological processes. Thermometrical devices and control technologies used for these purposes and especially for high temperatures are complicated and sold at a high price in the world market. Their price considerably surpasses their cost price and is determined by the monopoly industrially developed countries.
We propose:
Complex of methods and means for temperature gauging:
Periodical temperature gauging
- Contact temperature gauging
