Power-Flo® Hydronic Expansion Tank PFEXT8H - 8 Gallons

Thermal expansion occurs as domestic water is heated. Left unchecked, the resulting pressure increase can cause relief valve discharge and other potentially hazardous conditions. Therm-X-Trol® expansion tanks absorb this expanded water, keeping water pressure at a safe level. Features: Antimicrobial liner neutralizes bacteria on contact Patent pending Turbulator™ water diffuser 50 psi precharge - the industry's highest Deep drawn steel domes for 2X the strength of other tanks Thickest diaphragm for extra long life Hoop and groove design for added reliability Stainless steel system ...

Field Controls 8 Power Venter 740,000 BTU SWG-8 Patented SWG Venter is ETL and cETL listed for all LP gas, natural gas, or oil-fired heating equipment. Combines the motor, blower, and vent hood in one complete, easy to install unit. The SWG mounts on the outside of the building and pulls the combustion gases from the appliance through the outside wall utilizing 100% negative pressure. Made in the USA. Benefits: 100% negative pressure in the vent pipe for maximum safety. Standard galvanized pipe can be used instead of expensive stainless steel. No need to seal vent pipe joints, saving time ...

Low Pressure Brazed Plate Heat Exchanger, BP410-40LP Smaller, lighter, stronger, more efficent; Bell & Gossett Brazed Plate Heat Exchangers are ideal for residential and light commercial hydronic systems because they provide maximum heat dissipation. Unlike conventional shell and tube heat exchangers, our units can be used even in applications where space is at a premium. Their efficient design allows them to provide more heat transfer using less space, making them well suited to a variety of installations, including: domestic hot water, pool heating, radiant floors and snow melt. The ...

The Fan-in-a-Drum® is a commercial product designed to deliver combustion air into the mechanical room, boiler room or furnace location to overcome a confined space or inadequate air supply. Dual volt unit for oil or gas applications. When the thermostat calls for heat, the Fan-in-a-Drum® engages and begins drawing air into the structure. When air flow is established, the pressure switch closes. The CAS sends a signal to the appliance, allowing the burner to fire. The Fan-in-a-Drum® diffuses the outside air into the room near the burner to ensure adequate air for efficient combustion. ...
