Taco TB-15 - TB-15 20-Plate Stainless Steel Multi-Plate Isolator

The Taco Comfort Solutions® TB-15 20-Plate Stainless Steel Multi-Plate Isolator (Model TB10THx20) is a rugged, compact brazed plate heat exchanger engineered to create an efficient thermal bridge while providing total physical isolation between fluid loops. Constructed from premium 316L stainless steel plates vacuum-brazed with pure copper, this high-performance unit handles critical system tasks—such as separating a high-pressure outdoor snow-melt loop or open domestic hot water system from a sensitive, closed-loop cast iron boiler framework.

Key Performance Features:

• Corrugated Channel Engineering: The specialized herringbone pattern forces fluid into a highly turbulent flow profile, maximizing thermal transfer rates while effectively minimizing internal scale and sediment fouling.
• Gasketless Vacuum-Brazed Durability: Solid copper brazing seals every single contact point between the plates, forming a unified, leak-proof pressure vessel that completely eliminates traditional frame-and-gasket failure points.
• Compact System Footprint: Provides roughly 95% material utilization for direct heat transfer, serving as an incredibly space-saving, low-mass alternative to traditional shell-and-tube setups.

Application Profile: Featuring heavy-duty 3/4" male pipe thread (NPT) fluid ports, this 20-plate unit seamlessly adapts to radiant sub-floor arrays, residential snow-melting systems, outdoor wood boiler separations, and liquid-to-liquid water/glycol mixtures up to 50% concentrations.
