MF300 PressurePal feeder (17.0 gal) is ideal for feeding and pressurizing closed-loop heating systems with operating pressure of 25 psi and below. It allows for installation of stand-alone hydronic heating, radiant heating, snow/ice melting systems and forced air coil heat exchangers - without the need for running a separate potable water supply line. Axiom hydronic feeders are compatible with water and up to 50% water/glycol mix solutions and plug directly into a US standard electrical wall outlet - no special wiring or control boxes needed. MF300 is easy to install & service, saves time & labor and helps to prevent major flooding caused by leaks and ruptured pipes.


  • Compatible with water & glycol (anti-freeze) mixes;
  • Perfect for stand-alone hydronic and radiant heating, snow melting and heating/cooling coils;
  • Plugs directly into a standard 115VAC outlet;
  • No need for piping to a potable water supply - no need for backflow preventer;
  • Built-in diaphragm pump can run dry without damage;
  • Make-up fluid stored in the feeder tank can be pre-treated;
  • Diverter valve allows for easy purging of air on start-up and manual agitation of solution;
  • Major flood prevention - in the event of leakage or system rupture, only the tank contents will be pumped into the system;
  • Early leak detection - dropping fluid level indicate that the system has developed a leak;
  • Fluid drained for service can easily be re-used (put back into the system);
  • Fluid level switch shuts the pump off if fluid level in the tank gets too low;
  • Auxiliary dry contacts for (optional) low-level alarm installation.
