The MF200-S from Axiom is a SolarPal Solar System Mini Feeder (6 gallons). This item is ideal for feeding and pressurizing closed-loop solar systems with operating pressure of 35 psi and below. It's also suitable for higher-head hydronic, radiant, snow-melt and other heating and cooling systems with a higher static pressure. SolarPal allows for installation of stand-alone solar heating systems without the need for running a separate potable water supply line and installing a backflow preventer. 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. MF200-S is easy to install & service, saves time & labor and helps to prevent major flooding caused by leaks and ruptured pipes.

Features:

• Perfect for stand-alone solar systems and high-head hydronic/radiant heating, snow melting and heating/cooling coils;
• Compatible with water & glycol (anti-freeze) mixes;
• 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.
