Manual coolers with Certificates PED 2014/68 UE

The cooler is used for the manual withdrawal of the hot water to be examined. The water is cooled down to room temperature.

The cooler is intended to cool the boiler water to lower the temperature before the analysis.

The water is cooled by the cold water flow. Used to decrease the temperature before the analysis.

It is necessary to add: an inlet control valve to the hot water to regulate the flow and an inlet control valve to the cooling water.
Before sampling, open the cooling valve and then the valve of the water to be cooled.
Adjust the cooling water valve in relation to the temperature of the water to be examined, until the desired optimum room temperature has been reached. Cold water is considered cooling water.
It is not possible to mount a shut-off valve at the outlet to the water to be examined or at the outlet to the cooling water. Cooling water must not have back pressure.

Water flow regulation:

some analyzers (for example DUROMAT, DUROMAT Professional and Testomat) can give a signal before the analysis to open the inlet solenoid valve to cold water. This avoids the continuous flow of cold water.
