Example 1
This example requires a total output of 350kW and comprises
(4 x 80) + (1 x 30) models; the inclusion of the 30kW model
enables the greatest turn-down (40:1) but the maximum
permissible header pressure is limited to 40Pa.
Example 2
The heat requirement here is also 350kW; by selecting 3 x
120kW models (360kW) the maximum permissible header
pressure is raised to 80Pa which will enable greater ue
length. The turn-down ratio will be reduced to 12:1.
