Profile calibrator sucks water, not air.
An innovative calibrator reduces both the initial price and operating cost of a typical vacuum calibrator. Instead of the usual solid block of steel bored out with channels for cooling water and vacuum, Technoplast Kunststofftechnik GmbH in Austria uses a 3- to 5-mm micro-perforated steel plate backed with water at less than atmospheric pressure, drawn by a suction pump. Thus, cooling water inside the calibrator is pulled past the profile and through the microholes, holding the profile against the calibrator much the way a vacuum calibrator typically does. Energy use for the water-suction pump, however, is only 2.2 kw vs. 4.5 to 5.5 kw for three to five vacuum pumps on a typical calibrator. Technoplast, whose U.S. office recently moved to Cranberry, Pa., has sold 10 of these water-suction profile calibrators in Europe. Tel: (856) 241-3372 * PTDirect: 281ZP
