Control unit for cooling water: Waterguard In case of breakdown of cooling water for the condenser In case of breakdown of cooling water for the condenser
Principle of test: A set of similarly enamelled test specimens is to place by means suitable gaskets in the liquid and/or in the vapour zone of the test apparatus and exposed vapour zone of the test apparatus and exposed to attack by testing media under specified conditions. Specified conditions. The same design of test apparatus and the same test principle is employed for different liquids. The loss in mass or other parameters are determined and used to calculate the rate of loss in mass per unit area or loss of gloss and if necessary, the corrosion rate. General description The test apparatus consists of a cylinder, having a standard socket for holding a reflux condenser with a graduated collector on one side The cylinder is heated externally by a heater placed round the lower half of the cylinder. The electrical heater is controlled by an electronic controller.For processing an electrical connection (220 V AC), connection and plughole for water is necessary. By using mineralic acids as test medium the apparatus is to place in a laboratory fume hood. Testing apparatus can be completed with stand material for fixing the glass componets and other accesories 2.1 to 2.4 referred above and other accesories 2.1 to 2.4 referred above. Testing apparatos is usable for following test methods and standards DEZ-MB 7.3.2 enamel resistance against boiling water by long-term exposure DEZ-MB 7.3.3 enamel resistance against drinking water DEZ-MB 7.4.2 enamel resistance against hot soda solution DEZ-MB 7.4.4 enamel resistance against boiling sodium-pyrophosphate solution DIN/ISO 2742 enamel resistance to boiling citric acid DIN/ISO 2743 enamel resistance to condensing hydrochloric acid vapour DIN/ISO 2744 enamel resistance to boiling water and water vapour DIN/ISO 2745 enamel resistance to hot sodium hydroxide DIN/ISO 28706-2 enamel resistance to boiling acids, boiling neutral liquids and/or their vapours EN 14483-2 enamel resistance to chemical corrosion ISO 3972 part 2 sec 1 enamel resistance to citric acid
