Automatic water cooler big for analyzers

The cooler is used to decrease water tempertaure before an analysi.
Water is cooled down with a flow of cold water.

The cooler automatic big cools down hot water up to 120°C before an analysis.

Capacity regulation: a hot water inlet regulation valve needs to be added in order to regulate the flow and a regulation inlet water cooling valve.
Before testing open the cooling valve and then the valve of the water that needs to be cooled.
Regulate the inlet cooling valve according to the temperature of water to be analyzed until it reaches 40°C. It is considered cooling water the cold mains water.

It’s not possible to install either an output closing valve for the water to be examined or an output closing valve for cooling water. Cooling water cannot have counter pressure.

Water flow regulation: some analyzers (including Duromat Professional and Testomat) can give a signal before an anlalysis to open an inlet cold water electrovalve. This to avoid a continuous cold water flow.
