TECHNICAL INFORMATION ECOplus Solar Cylinder Minimized Heat Loss due to convection brakes in the pipe connections, the new close-fitting, 100-mm thick PU soft foam jacket insulation, 150-mm thick and close fitting lid insulation and 50mm thick floor insulation; with robust polystyrene shell. Connection option for CONVECTROL III – the Effective Convection Brake Technically optimized barriers separate the water cooled in the pipes safely from the hot storage tank water. This reduces heat losses at the pipe connections by up to 50 %. Optional Mounting Kit for Solar Station to minimize piping effort - time and space saving and neat appearance. Double Corrosion Protection with durable high-quality enamel coating and magnesium protection anode. Quick Installation with flat-sealing screw connections, combi-fittings, sensor terminal block, removable heat insulation with hook closure; horizontal attachment of the connection pipes made possible by CONVECTROL III. Stable Thermal Stratification due to slim column design with stabilized cold water inlet and hot water outlet flows. Lime-Scaling Resistant Heat Exchanger made from plain pipe coils for solar and aux. heating circuit, energetically optimized design, generously sized. High Quality Only high-grade and environmentally friendly materials are used. Manufactured and inspected in accordance with DIN 4753. Options for circulation pipe and electrical immersion heater. With cleaning flange. Figure 1  The ECOplus solar cylinder with volumes of 300, 400, 500 and 750 liters. Solar Thermal / Solar Cylinder   EN-XXX_ECOplus-Solar-Cylinder_TI-100126-11204200 1
