Apura: Cooler :

                                     Water to water cooler/ heat exchanger

                                                          Use: boiler room

  

The cooler is using for capture of hot water to examinate. 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 analysing. 

 

Models: "manual" model, destined to hot water sample for analysis with a testkit,” and “automatic” destined to cool the water before water analyzer. 

4 models available:

 Cooler "manual" small

                           Cooler "manual" big

 

 

                         Cooler "automatic" small                       Cooler "automatic" big

 

Capacity

 

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

Flow regulation of the water:

Some analyzers (for example DUROMAT XII 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.

* Free Chlorine /chlorine bioxide/ozone damages the inner surface of the cooler.

 ** Iron/mangle: might  be melted unmelted. If unmelted, filter it to keep out the hanging material. If melted, oxidize iron/mangle by a filtration plant or using a specific antiscaling  dosage.The scaling on the inner are usually removed with a chemical wash.

 *** Silicate, might scale the inner surface.

 **** Chlorite might damage the inner surface.

Further alterations are reserved in the interests of continuous technical improvements.
