CondenseMaster is a simple but effective solution for neutralising acidic flue gas condensate discharging from high-efficiency domestic gas-fired condensing boilers. Simply fitted to the boiler drain pipe, CondenseMaster provides environmental protection neutralising potentially harmful acidic waste before it goes to drain. The CondenseMaster cartridge incorporates patented internal geometry, which ensures that the treatment material will not leak from the unit during transport and the product will not become blocked during its 12 month lifetime, even when used with higher output domestic boilers. Particularly effective in periods where the boiler is only partially condensing and pH of the condensate generated is most acidic.
