Axiom SF100 Hydronic System Feeder - 55 Gallon

The SF100 contains everything required to feed and pressurize closed hydronic heating or cooling systems in a neat, simple package that is easy to install and operate. It is compatible with both water and water/glycol solutions

Axiom System Feeders are designed to simplify the process of maintaining the cold static fluid pressure in closed-loop heating and cooling systems. Having a reservoir of suitable make-up fluid eliminates the need for backflow prevention and helps solve many of the associated problems when using domestic water as a make-up fluid.


  • 55 Gallon tank for storage and mixing (208 Liter)
  • Plugs into any standard 115 VAC outlet
  • Fluid level switch shuts the pump off if the storage tank level gets low
  • Accumulator tank prevents excessive pump cycling
  • No direct connection to potable water supply eliminates need for backflow prevention
  • Make-up fluid stored in the feeder tank can be pre-treated
  • Diverter valve for purging of air on initial start-up and manual agitation of solution
  • Prevents major floods – in the event of system rupture, only the contents of the tank can be pumped into the system

  • Fluid drained for service can easily be put back into the system
