Brazed heat exchanger XB
Description
The XB is a range of copper brazed plate heat
exchangers for use in District Heating (DH)
and District Cooling (DC) applications, e.g.
domestic hot water production, district heating
substation to separate the network from house
installation or as pressure breakers. The range
consist of numerous individual plate sizes of
which several can be delivered with different
corrugation depth or pattern, thus ensuring that
the optimal heat exchanger can be selected for
all applications.
Main data:
- Min. temperature −10 °C
Max. temperature +180 °C
- Max. working pressure 25 bar
- Flow media
DH: Circulation water / glycolic water up to
50 %
DC: ethylene-, propylene-glycolic water,
ethanol-water solutions and other suitable
heat transfer media. (Please contact your
Danfoss representative).
- Connection size DN (threaded or flanged)
20 -100
Approvals:
• CE certificate according (PED) 97/23/EC
• GOST/Russia
• SVGW/Switzerland

Several of the heat exchangers can be delivered
in three different basic corrugations: H M L
making them optimal for different applications.

The heat exchanger can consist of plates type L
or plates type H.
The H- type plate has larger herring bone angle
than the L- type plate. H- type plate fits better for
certain temperatures than L- type. H- type heat
exchangers have better heating capacity, but
they also have higher pressure loss.
The plate set can also be a combination of these
two types. If every other plate is H-type plate and
every other plate is L-type plate, the combination
is called type M.

Micro Plate Heat Exchanger (MPHE) principle:
Traditionally the different versions have been
created by using different angles in the chevron
pattern of the heat exchanger plates.
However new and more efficient heat transfer
patterns have been developed. Characteristic
for the pattern is that the corrugation consists
of dimples in different size and shape, creating
Micro Plate heat exchangers. Micro Plate heat
exchangers offers same heat transfer with lower
weight, size and pressure drop. Besides better
heat transfer Micro Plate heat exchangers offers
higher mechanical strength.

To avoid corrosion and leakage in the copper
brazed plate heat exchangers please observe
Danfoss recommendations for the water quality
in the guideline on www.heating.danfoss.com
(Documentation).
For the standard range of heat exchangers
material 1.4404 (316L) has been selected to
achieve:
- good delivery service
- good balance between low price and
avoiding corrosion in the most common
applications
- 1.4404 offers better corrosion properties than
e.g. 1.4301 but is more expensive.
Attention must always be paid to the water
condition when selecting material for a heat
exchanger. The heat exchangers can be delivered
in other materials on request.

T212 - Secondary side second

The heat exchangers are made of shape-pressed
and brazed heat exchange plates, between
which the flow channels are created. The heavy
turbulence and counterflow principle enable
efficient heat transfer. The task of the heat
exchanger is to transfer heat from the primary
to secondary flow through a heat transfer plate
thus preventing the flows from mixing with each
other.
The choice of heat exchanger is determined by
the desired heat output, required temperatures
and the permitted pressure losses.
Sizing and selection Dimensioning and selection of heat exchangers
should be carried out with the support of
the Danfoss dimensioning program for heat
exchangers.
Mounting It is recommended to mount heat exchangers
on their base in vertical position. This will
assure the best venting and the least fouling.
It is recommended that all pipes connected to
the heat exchanger are equipped with shut-off
valves for maintenance purposes.
The 2-pass heat exchanger should be chosen for
domestic hot water. The 2-pass heat exchanger
will often cool the district heating water to below
25 °C. This capacity can be achieved by using a
larger temperature difference, a smaller water
flow and a heat exchanger with an optimum
heat transfer area. This will affect the choice of
motorized control valve, for instance.
The pipes must be equipped with brackets to
prevent any torsional stress concentration at the
heat exchanger’s pipe connections.
It is recommended that the heat exchanger is
equipped with insulation.
VD.JQ.C2.02
The pipes to be connected must be mounted so
that the strain caused by the thermal expansion,
for instance, does not harm the heat exchanger.
Use a safety valve between a heat exchanger and
a shut off valve on the secondary side to avoid
breaking of the heat exchanger due to thermal
expansion of liquid.
