As an example for a traditional cast-iron radiator, MS-140 is perfect, the assessment and working pressure of which is equal to 15 and 9 atmospheres, respectively. Similar radiators have been used for many years and have established themselves as a high -quality product. Due to the fact that cast iron has excellent thermal conductivity and is neutral to almost all types of coolants, cast -iron radiators can be used in heating systems with “poor” coolants (aggressive and contaminated coolants).
