Equipment classification (according to PED 2014/68 UE)
The cooler is using for capture of hot water to examine. The water is cooling bringing it up to environment temperature. Cooling takes place through a cold-water flow. The water to cool is cooled by the flow of cold water. Used to reduce the temperature of hot water before analyzing.
Models: “manual” model, destined to hot water sample for analysis with a ‘’testkit,” and “automatic” destined to cool the water before water analyzer.
We must add: a regulation valve in entry to hot water to regulate the flow, and a regulation valve in entry to cold water. Before drawing open the cooling valve than the valve of the water to cool. Regulate the valve of the cooling water according to the temperature of the water to examine, till the optimal environmental Temperature is achieved. The cool service water is considered cooling water. It is not possible to set neither a penstock valve in exit to the water to examine not in exit to the water to cool. The cooling water have not to have back-pressure
Some analyzers (for example DUROMAT and DUROMAT Professional) can signalize before the analysis to open the electro-valve in entry to the cold water. The continuous flow of the cold water is avoided in this way.
