This VWT-FFS-4372 Double Loop tunnel construction and its technology equipment are optimized for a professional use of sportsmen, army troop as well as general public and schools. Optimization of the fan can be performed on any other scenario of the use of the tunnel (like only sport tunnel utilization, or only to tourism utilization, military and special training purposes, or eventual their combination...). Optimization means a proper selection of tunnel dimensions, fans and engines parameters for proposed purposes to gain an optimal ratio between desired performance and operational costs. Dimensions and technical parameters of this tunnel offer the best conditions for the professional requirements on speed, space and height. Its size provides ample space for the entire training even of group formations of eight skydivers. Tunnel with 4,3 m of flying chamber diameter is the perfect place for training of army parachutes and special troops with their specific equipment. From tourist's point of view, the tunnel offers comfortable space even for flying couples with instructors or other smaller groups. Thanks to a comprehensive fan optimization the, tunnel allows operation of profi-flights as well as fun-flights at very low operation costs. Materials and Dimensions Air conductors in the aboveground part of the tunnel are made of sheet steel. All steel elements are provided with corrosion protection. Tunnel skin is made by sound-insulation panels KINGSPAN. Net dimensions of the tunnel are: width 30 m depth 10 m height 32 m The typical depth of foundation of ground concrete structure is 7,5 m. The typical height of the tunnel above the ground is 24 m. Flight chamber Flight chamber consists of a glass part, which is on its top connected to a steel construction of tunnel shell. Lower part of the flight chamber is purely cylindrical with a diameter of 4,3 m and a height of 5 m. The upper part of a flight chamber is made from steel and its height is 9 m. The shape of this part of flight chamber is gradually changing from a circular diameter of 4,3 meters to circular diameter 4,3 x 4,3 m. The overall maximum height of flight chamber 14 m The height of the glass part of flight chamber 5 m Diameter of flight chamber 4,3 m Maximum speed Maximum air speed at which the tunnel can be operated continuously is 80+ m/s (300+ km/h). Motors, fans and electronic equipment The air stream is formed by four vertically stored fans, each of 3.15 m in diameter, which are powered by a 4 electro-motors, each rated at 355 kW. RPM are controlled and regulated by 4 frequency changers from ABB. Control and monitoring system of the tunnel is realized using SIEMNS technology. Cooling Tunnel cooling is provided by an active cooling unit with a maximum power consumption of 330 kW, which corresponds to a maximum cooling performance of 1 000kW. Cooling compressor unit is located outside the tunnel and two pairs of optimized coolers installed in the tunnel design ensures a comfortable temperature in the flight chamber even during very warm summer period. During cold seasons, from the certain threshold temperature, the compressor unit is automatically switched to dry coolers, which maximize utilization of outside cold air and rapidly decrease the power consumption (up to 30 kW). -------------------- Offered price represents VWT-FFS-3672 /3.6m , double loop technology ,FOB Cz Praha 20x22ft containers

Miniminex led Flameproof luminaire - miniminex Type 591 40 01 I m2 ex d i mb Zóna 1, 21 • zona 2, 22 Use: for illumination in mines and underground spaces susceptible to firedamp. Also for other industrial places (indoor, outdoor or under shelter). See specification. Technical description: the luminaire consists of a body, led mod¬ule and flange with protective glass. Body and flange are castings from grey cast iron.Steel pendant with eye 18 mm is fixed to the up¬per part. On the sides of body are two cable glands for cable 17-19 mm (using the sealing rings 451.2717) and for cables 21 to 23 mm (using the sealing rings 451.2718). In the body is mounted led module consisting of a plate mounted leds cree xt-e type connected with cooling unit. Wattage lamps can be regulated (25 w / 12.5 w) by changing the output current (700 ma / 350 ma) for power supply. Flange with glass cover is framed and bolted to the body with six screws m8. The contact surface between the flange and the body of the fixture is a cylindrical joint of conclusion „d“. Protective hardened glass is resistant against mech. Shock min. 7 j and is fixed in the flange, the connection is filled with a polyurethan putty. A steel hinge is fixed to the flange as the mobile one and enables to hang up the flange during mounting or dismounting. Luminaire is treated with polyester powder coated, steel components are galvanized and chromated. Maximum section of connecting conduc¬tors is 4 mm2. The luminaire is designed as through-phase operation (five-core cable), when used as end with one cable gland blanking element. Packing carton is filled with polyurethane foam instapak. Weight 14kg
