  1. Determine the maximum medium flow rate for the hydraulic separator. The analysis shows, that the highest medium values are observed in the boiler system, and thus all calculations must be carried out for the boiler system.<\/li>\n
  2. Hydraulic separators selection type depending on the nominal flow rate. Select the hydraulic separator type with nominal diameter corresponding to the nearest higher value of calculated flow rate from the SP, SPP or SPD data sheet, Specifications\/nominal flow rate <\/strong>table.<\/li>\n
  3. Specify the device type (version, DN nominal diameter and shell diameter), see Hydraulic separator designation<\/strong>. Please specify if the special version (up to 150\u00b0C or supporting structure) is required when placing an order.<\/li>\n<\/ol>\n
