RHT Hydronic Fill & Purge System

Affordable fluid management for radiant heating systems

The RHT Hydronic Fill and Purge System meets a relatively high head pressure and flow rate (as shown in the figure below) for filling and purging air from hydronic systems. This is a great option for systems running glycol, or for any closed loop system that cannot be connected to a permanent domestic water supply. With the removeable 4" fill port fluids can be mixed in the 7 gallon container and pumped directly into a hydronic system. Return fluid can be directed back into the 7 gallon tank minimizing waste when using a glycol mix during the air purging process. See page 2 for purging diagram.

NOTE: The RHT Hydronic Fill and Purge System is not intended for use in line with or as feed to a backflow prevention and/or pressure reducing device. If used with such a device, the unit must be on a separate feed line into the system.
