COLLECTORS CONNECTION
The next chapter gives indicative information for the sizing of the water pipes to be connected to the panels. However,
the correct sizing must always be calculated by the engineer appointed to plan the specific system in question.
Metallic tubes that are suitable for contact with glycol solutions and high temperatures must be used. Similarly, the
hydraulic seals must also be suitable for contact with glycol solutions and high temperatures.
