Resideo TK30PV125SFM Tank Kit

The Resideo TK30PV125SFM Tank Kit is an all-in-one hydronic expansion tank solution designed to streamline professional installations. This kit features the Extrol Model 30 expansion tank, engineered to handle thermal expansion in closed-loop systems by maintaining internal pressure below the relief valve setting. Critical to system longevity, the package includes a Resideo SuperVent air eliminator with a 1-1/4 inch sweat connection, which utilizes a high-efficiency micro-bubble concentrator to strip entrained air from the system fluid. For consistent pressure management, the FM450 series fill valve (Fast Fill) provides reliable makeup water regulation. Using a pressurized expansion tank kit like this ensures a stable static pressure and prevents cavitation in the circulator pump. This serviceable expansion tank kit is built for heavy-duty boiler applications where eliminating air-related noise and oxygen-based corrosion is a professional requirement.

• Integrated Air Elimination: The SuperVent uses a unique internal baffle system to remove micro-bubbles and air pockets, preventing air-bound heat exchangers.
• Precise Pressure Regulation: High-performance boiler feed valve maintains consistent system pressure and simplifies the initial filling process.
• Pre-Charged Reliability: The Model 30 tank is pre-charged at 12 PSI, suitable for standard 2-story residential hydronic loops.
• Professional Grade Components: Features durable sweat connections for leak-free, permanent integration into 1-1/4 inch copper headers.

Common Questions

How do I check the pre-charge on the TK30PV125SFM?
Before installation and without system pressure applied, use a standard tire gauge on the Schrader valve. It should match your system’s fill pressure, typically 12-15 PSI for residential applications.

What is the purpose of the 1-1/4 inch SuperVent in this kit?
The SuperVent acts as the central air management hub, purging air that can cause hydronic system noise and reduce the heat transfer efficiency of the baseboards or radiant loops.

Can this tank kit be used in potable water systems?
No, this kit is specifically designed for closed-loop hydronic heating systems. Potable water applications require a stainless steel or lined thermal expansion tank to prevent contamination.
