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

• VA/Denmark

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

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.
