Resideo TK30PV125NK Combo Trim Kit
The Resideo TK30PV125NK Combo Trim Kit offers a comprehensive solution for managing thermal expansion and air elimination in closed-loop hydronic heating systems. This 4.4-gallon expansion tank combo kit centers around the TK300-30 expansion tank, engineered to handle pressure fluctuations and prevent system relief valve discharge. The inclusion of the PV125NK 1.25-inch NPT air separator is critical for high-efficiency operation, as it utilizes micro-bubble extraction to remove entrained air that causes pipe noise and pump cavitation. Designed for standard residential and light commercial boiler loops, this kit simplifies installation by grouping the boiler trim components into a single package, ensuring matched compatibility between the tank, air purger, and vent. By maintaining stable system pressure and eliminating air-bound zones, this kit helps protect heat exchangers and circulators from premature wear caused by oxidation and air-related friction loss.
- Matched Compatibility: Includes a 4.4-gallon expansion tank and a 1.25-inch NPT air separator for precise pressure regulation.
- Micro-Bubble Elimination: The PV series air separator effectively removes micro-bubbles, reducing radiator gurgling and component corrosion.
- Optimized Flow: 1.25-inch pipe sizing supports higher GPM flow rates suitable for larger hydronic zones.
- System Longevity: Prevents excessive pressure spikes that lead to recurring leaks and mechanical stress on the boiler.
Common Questions
Is the Resideo TK30PV125NK suitable for high-temperature boiler loops?
Yes, this combo kit is designed for standard hydronic heating applications where temperatures and pressures are maintained within residential or light commercial operating limits.
Why use a 1.25-inch NPT air separator instead of a smaller 1-inch model?
The 1.25-inch connection is used for systems requiring higher flow velocities to ensure the air separator can capture and exhaust air efficiently without creating excessive pressure drops.
Does this kit include a service valve for the expansion tank?
This specific trim kit configuration provides the primary tank and air separator components; installers should verify if additional isolation valves are required for their specific local plumbing codes.
This item is not eligible for free shipping.
