Description / application The X is a brazed plate heat exchanger designed for use with district heating systems (i.e. air conditioning, heating, domestic hot water). X brazed plate heat exchangers are made with several differently sized heat exchange plates. pprovals: C certificate according (PD) 97/23/C GOST/ Russia SVGW/Switzerland V/Denmark Main data: Min. temperature 10 C Max. temperature +180 C Max. working pressure 25 bar Circulation water / glycolic water up to 50% Connection size DN (threaded or flanged) 20 100 DHSMT/I VD.K.6.02 Danfoss 11/2007
Ordering xplanation, X type X 10L 1 10 Number of plates Pass of the heat exchanger 1 = 1pass 2 = 2pass Plate type Plate size = razed heat exchanger 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 Htype plate and every other plate is Ltype plate, the combination is called type M. Plate types H M L L H L L type H type H M type The same principal difference can be obtained with other plate patterns as well. 1pass brazed heat exchangers type X H L Type X 041 X 06L1 X 06H1 X 101 X 201 X 241 X 301 X 361 X 401 Connection No of plates, n Thread Thread Thread Thread Thread Thread Thread Thread Thread G ¾ G ¾ G ¾ G 1 G 1 G ¾ (G 1 )¹) G 1 G 1 G 1 8 0041011 0042024 0042036 0041004 10 0041012 0042025 0042037 0041005 0041205 0041027 0041405 0041070 0041605 16 0041014 0042026 0042038 0041008 0041208 0041028 0041408 0041071 0041608 20 0041016 0042027 0042039 0041010 0041210 0041029 0041410 0041072 0041610 26 0041017 0042028 0042041 0041013 0041213 0041031 0041413 0041073 0041613 30 0041019 0042029 0042042 0041015 0041215 0041032 0041415 0041074 0041615 36 0041021 0042030 0042043 0041018 0041218 0041033 0041418 0041075 0041618 40 0041023 0042031 0042044 0041020 0041220 0041034 0041420 0041076 0041620 50 0041024 0042032 0042046 0041025 0041225 0041067 0041425 0041077 0041625 60 0041026 0042033 0042047 0041030 0041230 0041068 0041430 0041078 0041630 70 0042034 0042048 0041035 0041235 0041069 0041435 0041079 0041635 80 0041440 0041080 0041640 90 0041445 0041081 0041645 100 0041450 0041082 0041650 110 120 140 160 180 200 for number of plates n 50 2 VD.K.6.02 Danfoss 11/2007 DHSMT/I

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. The 2pass heat exchanger should be chosen for domestic hot water. The 2pass 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. 6 VD.K.6.02 Danfoss 11/2007 DHSMT/I
Sizing 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 shutoff valves for maintenance purposes. 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. 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. Disposal The brazed heat exchanger is made of valuable stainless steel and copper which can be recycled. Insulation sets can be disposed of in incineration plants thus recovering the energy or disposed of in landfills. lways follow local waste disposal regulations!
