NT25 NeutraPro

NT25 NeutraPro

The NT25 is ideal for neutralizing condensate from condensing boilers and furnaces operating on natural gas or propane.

The condensate produced by these appliances is acidic and has the potential to harm the environment and the sewer system. The NT25 will neutralize the condensate to a more neutral pH level before it is discharged to drain.


  • 45 Gal/hr (170 l/hr) or 80 Gal/hr (300 l/hr)with two in parallel *
  • NeutraPro prevents acidic condensate from corroding drains and sewer systems
  • Neutralized condensate is more environmentally friendly
  • Two 1” NPT inlet/outlet connections with unions for fast and versatile installation
  • Low profile design for appliances with near floor condensate drain
  • Tank and lid made from durable and corrosion resistant Polypropylene
  • 18 liter (4.8 US gallon) tank with baffles designed to channel flow through LipHter media for complete neutralization
  • Integral bypass feature prevents condensate backflow into appliance
  • Includes initial charge of Axiom’s special LipHter neutralizing media

  • * Check with the appliance manufacturer for condensate flowrate. As a guideline 7,000,000 BTU/hr at 96% efficiency will produce approximately 45 Gal/hr (170 L/hr) and 12,000,000 BTU/hr at 96% efficiency will produce approximately 80 Gal/hr (300 L/hr).
