The pipes are 000017 26 made of stainless steel 1.4404, the fittings of brass. 000018 26 An optional thermal insulation reduces heat 000019 26 dissipation and prevents heating of the cold water by 000020 26 separating the hot and cold pipes. Insertable 000021 26 elements integrated in the upper thermal insulation 000022 26 shell allow recesses for the water meter, the heat 000023 26 meter, as well as the heat exchanger to ensure rapid 000024 26 cooling of the heat exchanger after a tapping process. 000025 26 With the optional thermal insulation, the 000026 26 installation depth of 110 mm is not exceeded. All 000027 26 wetted parts on the potable water side are made of 000028 26 brass, stainless steel 1.4401 and 1.4404 and potable 000029 26 water approved plastics. 000030 26 000031 26 With an asymmetrical arrangement of the stainless 000032 26 steel plates of the heat exchanger, as well as a 000033 26 pressure loss-optimised design of the station, the 000034 26 station allows particularly efficient operation and 000035 26 enables hot water volume flows of 20-30 l/min 000036 26 (performance range 3) at excess temperatures of 0-15 000037 26 K (according to SPF test procedure). This means that 000038 26 discharge capacities and excess temperatures can be 000039 26 individually adapted to the existing system 000040 26 parameters. The low excess temperatures make the 000041 26 station particulary suitable for operation in low 000042 26 temperature systems. 000043 26 000044 26 The adaptive electronic control independently adjusts 000045 26 to the operating conditions in the overall system. 000046 26 The set potable water temperature is constantly 000047 26 controlled, regardless of system temperatures, 000048 26 pressure loss ratios and required draw-off qunatities. 000049 26 A demand-controlled priority circuit of the 000050 26 multifunctional control valve ensures intelligent 000051 26 energy distribution for hot potable water preparation 000052 26 as well as for the the heat supply of a residential 000053 26 unit. 000054 26 In heating mode, the integrated differential pressure 000055 26 control of the control valve ensures efficient heat 000056 26 distribution between the stations. Hydronic balancing 000057 26 in the pipe network to the station is therefore 000058 26 unnecessary. 000059 26 In the event of a power failure, a failsafe mode is 000060 26 activated. In failsafe mode, the actuator closes the 000061 26 control valve to prevent uncontrolled heating of the 000062 26 potable water. 000063 26 A status LED indicates the current operating status 000064 26 of the station. 000065 26 000066 26 The copper brazed stainless steel heat exchanger 000067 26 features a protective layer on the primary and 000068 26 secondary sides. The optimised surface structure 000069 26 decreases the risk of calcification and reduces 000070 26 deposits. The media resistance on the primary and 000071 26 secondary side is improved. Due to the protective 000072 26 layer, the heat exchanger can be used in critical 000073 26 potable water regions with a high electrical 000074 26 conductivity >500 µS/cm and a chloride content > 000075 26 100 mg/l. An exact check of the materials that can be 000076 26 used is recommended on the basis of a potable water 000077 26 analysis and supplementary sheets provided by the 000078 26 manufacturer. The heat exchanger with protective 000079 26 layer also prevents metal migration into the potable 000080 26 water and heating water due to the surface with 000081 26 protective layer. 000082 26 000083 26 The Regudis W-HTE basic station can be individually 000084 26 extended with the following functions in a 000085 26 time-saving manner my means of a modular plug and 000086 26 play assembly concept: 000087 26 Mixed heating circuit (flow temperature control 000088 26 module) Simultaneous supply of an unmixed and a 000089 26 mixed heating circuit (heating circuit connection 000090 26 fitting) Potable water circulation (potable water 000091 26 circulation module) Electrical reheating of the 000092 26 potable water (instantaneous water heater module) 000093 26 System separation of the heating circuit on the 000094 26 dwelling side from the heating circuit on the 000095 26 building side (Duo heating circuit separation module) 000096 26 The Regudis W-HTE dwelling station consists of the 000097 26 following components: 000098 26 Connection box for power supply 230 V AC, rated 000099 26 current 50 mA, output voltage 5 V DC, rated output 000100 26 current 1200 mA, protection type IP 65, protection 000101 26 class II, overvoltage category III, ambient 000102 26 temperature 0-60 °C Actuator with integrated 000103 26 potable water temperature control 40-70 °C, max. 000104 26 ambient temperature 0-60 °C, power consumption 0.15-3 000105 26 W, protection type IP 54, input voltage 5 V DC 000106 26 Volume flow sensor (enables volume flow detection 000107 26 from 1 l/min) Vent valve in the heating circuit 000108 26 Multifunctional control valve for high flow rates 000109 26 with integrated differential pressure control valve 000110 26 and demand-controlled priority circuit for hot water 000111 26 preparation Drain valve in the primary circuit 000112 26 Zone valve for heating circuit control Drain valve 000113 26 in the heating circuit with strainer Copper brazed 000114 26 plate heat exchanger made of stainless steel 1.4401/1. 000115 26 4404 with protective layer PT 1000 temperature 000116 26 sensor for hot water Connection for potable water 000117 26 circulation module G 1 Spacer for heat meter G ?, 000118 26 110 mm Spacer for water meter G ?, 110 mm 000119 26 Connection for derivative temperature control set M 000120 26 22 x 1 Filter insert in the primary supply 000121 26 Connection in the primary supply for the temperature 000122 26 sensor of the heat meter M 10 x 1.0 Performance 000123 26 data potable water: 000124 26 Hot water capacity heat exchanger: 55-84 kW 000125 26 (performance range 3) 000126 26 at 50-65 °C primary and 10 °C/50 °C secondary 000127 26 Draw-off quantity: 20-30 l/min (according to SPF test 000128 26 procedure) 000129 26 Pressure loss secondary: 300-650 mbar (without cold 000130 26 water meter) 000131 26 3 ball valve connections DN 20 000132 26 000133 26 Performance data heating: 000134 26 Heating output: 14 kW, delta T 20 K 000135 26 max. 600 l/h 000136 26 Max. differential pressure: 2.0 bar 000137 26 Min. differential pressure: 150 mbar 000138 26 Pressure loss primary: 150-250 mbar (without heat 000139 26 meter) 000140 26 4 ball valve connections DN 20 000141 26 000142 26 General data: 000143 26 Max. operating pressure: 10 bar 000144 26 T max (primary): 90 °C 000145 26 Ambient temperature: 2-35 °C 000146 26 WxHxD (without ball valves): 600 x 455 x 110 mm 000147 26 Centre distance to the connections: 65 mm 000148 26 Centre distance to the wall: 26.5 mm 000149 26 Weight: 10.2 kg 000150 26 000151 26 Extensive accessories: 000152 26 Flow temperature control module for surface heating, 000153 26 heating circuit connection fitting, potable water 000154 26 circulation module, instantaneous water heater module, 000155 26 Duo heating circuit separation module, upper thermal 000156 26 insulation shell, derivative temperature control set, 000157 26 flushing and mounting bridge, earthing clamp, 000158 26 connection and shutoff set, flush-mounted cabinets, 000159 26 surface-mounted cabinets, revision frame, Regubox 000160 26 exclusive surface-mounted bonnet 000161 26 000162 26 000163 26 Nennweite: DN20 - 3/4 000164 26 Anschluss: Internal thread 000165 26 000166 26 Art.-Nr.: 1344052 000167 26 EAN-Code: 4026755446944 000168 26 Hersteller: OVENTROP GmbH & Co.
