STANDARD UNVENTED SYSTEM KIT EXPANSION VESSELS
The following information is based on an inlet pressure of 3.5 bar and an expansion vessel efficiency of 0.45 using a standard 6 bar unvented
kit. If the system will have different parameters a more detailed calculation will need to be made.
V V = S V * e
0.45
Where:
V V = Vessel Volume
S V = System Volume
e = Coefficient of Expansion (See Table 10.1)
