The Krechet space suit was developed by NPP Zvezda in the framework of the Soviet lunar program. Since it greatly differed from its American counterpart, the requirements to the suit were also totally different. This challenge allowed the developers to set several technological records. Thus, the Krechet suit could provide 10 hours of autonomous support for the astronaut working on the moon, which is enough for a five-kilometer walk. The suit was equipped with two independent air conditioning systems: the first one ensured steady circulation and regeneration of the atmosphere, and the other (the KBO model presented here) was responsible for the heat removal. To do this a special suit would have to be put on under Krechet which had a total of about 100 meters of tubes of flowing water sewn into it. Thus, it was possible to remove about 400 watts of heat. But everything comes at its price: the weight of the water suit was more than three kilograms, while the Krechet suit was not designed for wearing at all — it was so big and heavy that the astronaut had to "enter" it through the hatch in the back. Krechet was never used for its intended purpose due to the cancellation of the lunar program. However, most of its systems, including the KBO were applied in the development of the Orlan series of space suits, which are still used in space.
