NEW Water Cooling System

At the moment our water system has three outputs: A - B - C. The incoming water in filtered, before the outputs, at 25 um. In addition the outputs have the following dedicated filters:
A-> 10 um || B -> 20 um || C -> 10 um

Device	Temperature (°C)	Flow (l/min)	Pressure (bar)	Max Output Temp.	Power dissipation1	Water use	Internal element	Max filter size

1: The power is calculated assuming incoming water at 17°C
^x:These devices are connected in series. Output temperature is due to the power dissipation of all of them.

Real Power consumption:

Output	Flux	Pressure	Power to dissipate
A	4 l/min	3 bar	3.0 kW
B	8 l/min	4bar	3.5 kW
C	2 l/min	2bar	620W
Other	5 l/min	4 bar	~1,5kW

Total incoming flow: 24 l/min
Incoming pressure: 6bar
Total real power to dissipate via water: ~ 8,7 kW\\
