Expansion vessel

The expansion vessel installed on the boilers has the following

characteristics:

Description

U/M

Brava One OF ErP

Total capacity

8,0

Prefilling pressure

kPa

100

bar

1,0

Useful capacity

4,0

Maximum system content (*)

109

(*) Conditions of:

Average maximum temperature of the system 85°C

Start temperature at system filling 10°C.

CAUTION

– For systems with water content exceeding the

maximum system content (as indicated in the

table) an additional expansion vessel must be

prearranged.

– The difference in height between the relief valve

and the highest point of the system cannot exceed

6 metres. If the difference is greater than 6 metres,

increase the prefilling pressure of the expansion

vessel and the system when cold by 0.1 bar for each

meter increase.
