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. 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.
