Professional tube factory (UNITRA ZLP)
Al. Solidarności in Warsaw. View towards Bielańska street. Ruins of the pre-war National Bank of Poland. After the war,
which for some time was the seat of the Professional Tube Factory. Formerly, behind the visible fence covered with posters,
there were ZLP barracks, now dismantled. About this plant is known relatively little, so the following article contains a certain amount of conjecture.
There are three registered offices of the Professional Tube Factory:
- - at Elekcyjna 106/Ciołka 8 in Warsaw
- -at.Bielańska 10 w Warszawie
- -in Piaseczno (probably today's Okulickiego Street)
At ul. Elekcyjna 106 in Warsaw was located Experimental Department of the Industrial Electronics Institute (ZD PIE) at the end of the 1950s. According to oral
transmissions in the 1960s, Elekcyjna Street changed its course and the factory changed its address to Ciołka 8. The ELW1 tubes (equivalent E1T) were definitely
produced in ZD PIE. According to verbal accounts, night vision transducers were also produced there. However, this information is difficult to consider
as completely certain. However, there are facts that confirm this. For it is known with certainty that these transducers were produced until the 90s on the
9th floor of the OBREP skyscraper at Długa 44/50 (the so-called building D). However, it is known at the same time that after the separation of PIE and OBREP
at Ciołka 8 in the early 1970s, the OBREP unit was located. At the beginning of the 1980s (some indicate here the times of martial law) the OBREP branch
at Ciołka 8 was collapsed. It is possible that the production of night vision transducers has simply been transferred to ul. Długa 44/50 after the
liquidation of the office at ul. Ciołka 8. At the end of the branch's activity at Ciołka Stret was also produced there emission pastes.
This part of the activity was moved to the office at ul. Długa 44/50 and continued until the end of the first decade of the 21st century. In the employees' memories
there is information that Ciołek 8 also housed the CRT repair workshop called "Reskop". This is possible given that in the 1960s, PIE developed 17-inch black
and white cathode-ray tube technology, which certainly required some technical support.
