\u00a0<\/p>\n Because of its numerous advantages, systems that have adopted\u00a0Greenway\u00ae Neo Solar<\/a> react better to overheating, displaying greater resistance.\u00a0 The systems have a longer life span and are efficient in the long term, yielding a good return on investment.\u00a0 Convinved by its qualities, the company Solartrade Kft then came out in favour of Greenway\u00ae Neo Solar<\/a>.\u00a0<\/p>\n \u00a0<\/p>\n The monopropylene glycol antifreeze previously used in such systems was replaced, as it was observed that the acid concentration of this fluid increased at high stagnation temperatures, with the circuit beginning to “tar”. The second reason for its replacement is the fact that in sunny winter conditions, monopropylene glycol may turn into sludge, which makes it difficult to prime the pump and increases energy consumption.\u00a0 No such changes are observed with Greenway\u00ae Neo Solar<\/a>; the properties of this heat transfer fluid\u00a0make regulation and adjustment easy.\u00a0<\/p>\n \u00a0<\/p>\n![\"\"](\"\/wp-content\/uploads\/2022\/09\/uploadsassetsCase_studiescase_study_greenway_2012_HU__3_.jpg\")
At temperatures above\u00a0150\u00b0C,\u00a0Greenway\u00ae Neo Solar<\/a> degrades 4 times slower that a conventional solution based on monopropylene glycol, which enables a dramatic reduction in corrosion and “tarring”, while avoiding the risk of the collectors becoming clogged.\u00a0 At 100\u00b0C, it expands half as much and its technical properties remain\u00a0stable.\u00a0 It requires less energy to pump due to its low viscosity.\u00a0<\/p>\n

The building was approved in December 2011 and since then, energy-saving and efficiency measurements have been taken regularly.\u00a0 The system has produced 62 MWh of energy in approximately 5 months, to the satisfaction of the residents.
