DMF300 PressurePal feeder (19 gal) with digital pressure control (0-45 psi) is ideal for feeding and pressurizing closed-loop heating systems with operating pressure of 45 psi and below. It allows for installation of stand-alone hydronic baseboard/radiator heating, radiant floor 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. DMF300 is easy to install & service, saves time & labor and helps to prevent major flooding caused by leaks and ruptured pipes.
