DC Industrial Ceiling Fans Cost effective air circulation that can save up to 30% on winter heating costs. Mount to wall, ceiling or overhead joist. Galvanized Steel adjustable three way mount. CFMs range from 200 to 3400 and sizes 8" to 20" CA-AG-EC Basket Circulating Fans Energy efficient with power savings up to 75%. SD-EC Standard Exhaust Fan Exhaust fan with high efficiency totally enclosed EC Smart Motor. The result is an ENERGY EFFICIENT motor that runs COOLER than any other in the industry. ECsmart Motor EC motors are electric motors that have permanent magnets on the rotor and use electronics to control the voltage and current applied to the motor. Weather station option adjusts for wind and rain direction. Control and automate curtains, fans, and heaters with support of multiple temp probes. Unity NATVENT Wide range of capabilities at a very competitive price. Easy no weld fence and gate system, and slide in ends. Available up to 12' high with heat welded joints for easy installation, and UV inhibitor coating for increased life span. Crystal Clear Curtain New fabric for natural ventilation systems provides maximum light penetration. Heavy duty mounts protect trough in high traffic areas. Round Bottom Trough with Mounts Easy to tip and clean trough designed to keep cows safe from corners, pivoting assembly and float cover. Can create an evaporative cooling effect of three to four degrees throughout the facility. The use of jet pump materials handling for the excavated material means it is now possible to achieve drives up to 20 times longer than previously. Fanbos Blankets a very large area by constantly moving air to create an expansive comfort zone. Fans run at a very low speed which reduces the noise level well below that of high-speed fans. Serco HVLS Fan Provides high-quality velocity cooling in the summer and recirculates warm air from the ceiling in the winter. Dual action swinger provides safe operation for cattle. Self Locking Feed Front Quick and easy individual or group lock and release. Lift Crate Floor raises when sow stands to prevent piglets wandering underneath, reducing crushing. By rotating it 180° in the launch shaft it can also handle the retraction of the cable protection pipe and thus takes on a double function.FGC Fiberglass Fans High efficiency, heavy duty exhaust fans with low maintenance and installation costs. Herrenknecht developed an appropriate jacking frame especially for these jacking pipes with a 10 meter stroke and a thrust force of 350 tonnes. The method innovation involved the development of new, extended jacking pipes that allow a practically continuous advance. In a second step, final insertion of the underground cable is carried out by suitably specialized companies. After installation of the protective pipe, the E-Power Pipe® mission is complete. Subsequently, the prefabricated cable protection pipe is connected to the jacking pipes still located in the borehole and fed into the launch shaft via the jacking frame. After breakthrough at the target point, the pipe jacking machine is separated from the jacking pipes. The borehole remains securely supported by the machine and the jacking pipes the whole time. With the E-Power Pipe® technology, Herrenknecht has developed a new method that closes this gap.Īt the starting point a jacking frame is installed, with the feed force of which the jacking pipes and the TBM are pushed along the specified route in the direction of the target point. In the area of non-accessible diameters for the individual installation of underground cables, until now no trenchless construction method has met all the criteria in terms of cost-effectiveness, safety, security and construction time. The main requirement is to install the cables at a shallow depth and at rigidly defined small distances apart with high precision over the greatest possible distances (up to 2 km). This is particularly true in densely populated regions such as Germany.įor the grid expansion planned in Germany (Grid Development Plan Power 2030, version 2017, 2nd draft), around 2,400 kilometers of new high-voltage direct-current transmission lines (HVDC) are needed, most of which are to be installed as underground cable. For this the time and budget plans of the authorities and planners often have to be adapted to the demands of local residents and property owners in laborious and time-consuming procedures. The expansion of power transmission grids and the construction of new trunk lines are typically carried out with overhead lines.
