Hydraulic connection into a system
The R40 must be connected in such a
way, that a minimum flow rate of 30%
of the nominal flow rate can be ensured
at all times, independent from the flow
rate in the sec
o
ndary system. The R40
can be used in single and cascade
ap
plications, with low loss header or
plate
heat exchanger.

By using a low loss header or plate
heat exchanger a minimum flow rate
can be ensured at all times, indepen-
dent from the flow rate in the sec
o
ndary
system. The boiler pump is available as
a standard 3-step or a speed controlled
version. The speed controlled pump
modulates the flow rate in the primary
system in parallel with the burner load.
This ensures the lowest possible return
temperature to the boiler for high
effici
ency usage.
Details of the available pump kits can
be found in the chapter
