<p>A system for supporting sales and maintenance activities of steam traps by a seller of the traps to a customer. The system utilizes an aggregating system which effects the steps of: inputting stored diagnostic result data and model confirmation result data from a diagnostic device which has diagnosed a working condition of each of a plurality of existing steam traps installed in a customer's plant; calculating, based on said diagnostic result data, a first total steam loss amount due to malfunction of steam traps, the first total steam loss amount comprising aggregation of steam leak amounts of all the existing steam traps; calculating, based on said model confirmation result data, a second total steam loss amount, which comprises aggregation of differences between inherent steam leak amounts of the existing steam traps under their normal working conditions and inherent steam leak amounts of recommended steam traps under their normal working conditions; calculating a monetary conversion value of an integrated value of a sum of the first total steam loss amount and the second total steam loss amount integrated for a predetermined period; generating comparison data allowing comparison between said monetary converted value and a replacement cost required for lump-sum replacement of all the existing steam traps by the recommended steam traps; and outputting the comparison data for presentation to the customer in sales and/or maintenance activities of the recommended steam traps. <IMAGE></p> |
