Brazed Plate Heat Exchanger, 30-Plate 5x12 Water-to-Water

Brazed plate heat exchanger transfers heat fast between two water circuits, helping you stabilize temperatures while reducing pump load. Built from 316L stainless steel with copper brazed joints, it’s designed for high-pressure, high-temperature hydronic applications like radiant floor heating, domestic hot water preheating, snow-melt loops, and brewery or process cooling. The 30-plate, herringbone channel design increases turbulence for efficient heat transfer in a compact footprint.

• Delivers rapid heat transfer with 30 asymmetrical herringbone plates for strong turbulence and stable performance.


• Resists leaks using vacuum copper brazing plus helium leak testing to reduce micro-leak risk over time.


• Handles demanding loops with 316L/304 stainless steel construction rated for -292°F to 392°F operating temperatures.


• Fits common plumbing using 4 ports with 1-1/4" MNPT external threads for water-to-water systems.


• Includes mounting brackets for secure, rust-resistant installation and easier service access.

When your hydronic system needs compact output without complicated maintenance, this stainless steel water-to-water heat exchanger is a practical upgrade. The thickened interface and brazed construction support consistent flow and dependable connections across heating and cooling circuits, from radiant floor manifolds to snow melting and beer cooling setups. Choose it for tight mechanical rooms, retrofit projects, or new builds where space and efficiency matter. Install with the included brackets, connect your supply/return lines, and put your system on a steadier temperature track. Grab yours today.
