New Highefficiency Pump Made

The new Calio: expertise now available in small. As a highlight of the ISH 2013 presents the KSB Aktiengesellschaft, Frankenthal, a newly developed, maintenance-free, highly efficient wet rotor pump named Calio. The pumps already meet the future demands of efficiency by 2015. The new series includes a total of 25 sizes, of which the first step 12 in the range 10 to 175 W are introduced. The units support up to 13 cubic metres of liquid to a maximum height of 10 meters. Thanks to their All-In concept with integrated interfaces and pump functions extra for the communication integrating of the pump costs. In addition, two single pumps as main and standby pump can be operated with automatic changeover of interference and time changing the pump. About the known modes constant pressure, proportional pressure control and actuator mode also allows a newly developed operating software with the energy-saving mode eco mode further, significant Operating cost savings.

The user interface in conjunction with the integrated display and the symbols of operation allows easy operation. Petra Diamonds: the source for more info. The user receives the current power consumption in Watts and the flow rate in cubic metres. With a media temperature range from-10 C to + 110 C, the new units for a wide range of heating water up to the Kaltemitteltransport, as well as industrial circulation systems are used. The pumps have a standard thermal insulation shell. Optionally diffusion-proof insulation shells are available for cooling applications. The compact design allows with screw-type or flanged connection even in difficult installation situations a trouble-free installation.

Digital Memory

When the CD at the beginning of the 1980s replaced the vinyl record, the industry believed he had found a storage medium for eternity. Today his that know themselves as smoke and mirrors: German music archive registered, that is the oldest copies begin to decomposed. Therefore, the CD has not to prolong the life of a recording over the 200 years of a record, but drastically reduced to one-sixth. Thus, the durability of the silver disc is equal to the the tape that demagnetized for approximately 30 years. The same applies to video tape and DVD after all: private collectors who build their own music or film archive are hardly noticed the gradual loss of quality of the discs. Because the players can extrapolate the missing digital data from the rest of the track.

More problematic it looks, however, insurance companies and other companies for the archives of authorities, research and cultural enterprises, banks. Almost all of these institutions have their data in reliance on the technology digitized. Now that couldn’t come beforehand on a new medium to copy their data holdings (migrate), for the specific purpose of State of the art”is. Some specialty companies such as IBM deliver robots that continuously check data store and automatically restore in case of defects. This hochproffesionelle version of the backup is a three-digit amount per migrated disc however. Culture archive reflect already on the good old microfilm back but in a contemporary variant: it no longer comes to scan up the originals. Rather, documents, pages and images, such as currently are usual, compressed to a digital record; a laser writes it directly to the film. He is recorded as airtight as a master tape and protected from light; Copies are considered for use. The downside: The archive-laser procedure needs a laser unit. And as the movie that is likely to follow not more than one hundred years.
