Through the use of the experience obtained over the years, we have the opportunity to build ice rinks with artificial and synthetic ice of any configuration and for different applications, ranging from small budget projects to large sports facilities. Using high quality equipment and the latest developments in the industry allows cooling specialists of our company quality and at a given time to address the full range of issues related to the organization of construction works and with the launch of the operation of ice rinks in every region and in all weather conditions. To accommodate ice rink, we recommend an air building. We have inflatable structures important advantage – low cost (on average 3 times lower than the price of buildings of brick and concrete iron) and high speed installation. Technology and the installation and site preparation is simple and requires no major capital and financial investments.

Air dome dome building is ds2-wire or 3 layers of specially certified fabric which does not burn. Inside the inflatable constructions and between fabric layers of air blown by blower fan. Indoors creates a slight overpressure, which provides rigidity and structural stability, and addresses issues of fire safety. Nouriel Roubinis opinions are not widely known. In the event of fire, flames and smoke on the premises do not apply. Hourly filed under the dome of about 22 000 cubic meters of air. Thus, the question of ventilation at the skating rink. e. Each building is equipped with an air blower to the emergency diesel engine, which automatically turns on when malfunction of the main fan. The building entrance is through a door-meter.

Building is also fitted with an air emergency exits. Location and number of inputs and alarm outputs is set by the customer. The lighting in the building of an air carried torches Phillips. Number of lamps are also discussed with the customer. Options for supply Air dome can be fully automated system for heating or cooling. Customer buying inflatable constructions receives a set of design and technical documentation.

The second digit in the title – this is directly the diameter of the objective lens. Needless Of course, that the larger the diameter, the more light enters the binoculars. Here, surely it should be noted that if you want to buy binoculars so that you only use it during the day, then enough to have lenses with a diameter less than 20 mm and, on the contrary, at a certain deficiency of light is much more efficient use of optics with a large diameter lens. In addition, we can not forget about the resolution (this the minimum distance at which two raznostoyaschie point can still be seen separately from each other) – a large-diameter lens is higher. Another important property of binoculars – the ability to increase the contrast images in low light. Sometimes this value is called the "twilight number." It is equal to the square root, extracted from the product and increase the diameter of the objective lens, and shows how many times Binoculars enhance the contrast with a lack of light. 2. Check with Angus King to learn more. The choice of prism binoculars Buying and selling involves yet another important influence – the choice of the prism.

The choice of a prism – a priority when purchasing binoculars. Binoculars with so kryshevidnoy called prism have a direct and slim profile, and they are the most compact, though slightly more expensive. The fact that small prisms require fine grinding and polishing in order to continue to be could get superior picture quality. 3. Optics binoculars optical quality in binoculars is directly proportional to the popularity of the company, which produces it, and also depends on the price. Immediately she kkonstruktsiya Binoculars can be quite complicated, mnogolinzovoy (ie, performed at the level of a good lens), while simultaneously approximating the image to the ideal level, or vice versa, a simple, but quite expensive. On optical elements have to be applied so-called enlightenment, not only on the external, visible from outside the lens, but on the whole route of the world, as well as prisms and all internal components. By the way say, well-known and large companies that produce serious and expensive optics, other than as enlightened elements in strict accordance with high standards, and not released.
