SRT CR high-speed retractor gate....

SRT CR: the new yardstick for tightness in the pure area. The SRT CR (Clean Room) is conceived by the compact and in itself closed building method for all in-plant openings in pure areas. This Tora situation was developed according to the current standards for the pure space industry and is the ideal conclusion for areas with different pressure ratios. Contrary to conventional gate constructions with this Tora situation by a quasi closed Behangfuehrung an air passage is ensured by smaller 100 m3/h with a maximum air pressure difference by 150 Pa. The entire gate construction is naturally in high-grade steel (V2A) implemented and with a diagonal complete cover available. When desired special covers can be realized according to internal regulations (e.g. senkrechte glare to a suspended cover).High airtightness at the transitions of differently classified pure areas usually prevails a differential pressure. The closer the Tora situation is, the less achievement for the maintenance and for the reconstruction of the positive pressure after closing the gate is needed. The SRT CR achieves the high airtightness by a gate paper feed closed in itself. Compact Design particularly the pharmaceutical industry attaches great importance apart from the tightness in principle demanded to easy cleaning bar and the avoidance of supernatant edges, because floating particles could set off there. For this reason both the drive and the switchgear cabinet are integrated in the trim. Thus also a responding optics developed apart from the smooth building method.The usual note tri gel lever was replaced by a sunk push-button actuator, which ensures the exhaust brake over a USV ventilated and thus the opening of the Tora situation also with power failure. Many application type the SRT CR is suitable due to the design and the airtightness for the installation in pure areas of the class 8 according to DIN EN ISO 14644 (corresponds to the class to 100,000 to US FED STD 209) for the bulkheading pure areas of the class 7 (10,000 after FED STD). The Microprozessor control (MCPS) and the frequency changer provide for almost maintenance-free run and high life span. This combination offers an opening velocity of 1,0 m/sec, the closing speed amounts to 0.5 m/sec.
