The Spirax Sarco feedtank is an atmospheric deaerator fully constructed in stainless steel – no rusting, no linings, coatings or joints to leak. It is fitted with a flash condensing deaerator head which combines: cold make-up, condensate return and flash recovery. Flash steam is condensed whilst heating and deaerating the cold make-up. The deaerator head is also available for fitting into existing feedtanks.
