B-C-E: Boiler control via 0-10VDC + cascade via plate heat exchanger
Description
R40 with plate heat exchanger
Cascade control
Tips
Complete accessory kits with plate
heat exchanger are available for
∆T=10-20K (see chapter
"Accessories").
The primary circuit should be
designed for ∆T=20K, this guarantees
a high boiler efficiency.
When the secondary circuit is
designed for a ∆T smaller than 20K,
the flow temperature of the plate heat
exchanger will be lower than the flow
temperature of the boiler. This should
be taken in to consideration during the
design stage.
The plate heat exchanger should be
positioned close to the boiler, to avoid
a negative influence on the
temperature control quality.
In case of a boiler room installed on
the roof, the boiler may never be
hydraulically connected at the highest
point of the installation.
