HXM series · SUS304 plates · copper brazed
HXM Brazed Plate Heat Exchangers
30 to 60 plates · 200,000 to 600,000 BTU/h
High-efficiency heat transfer for hydronic heating, snow melt and chilled-water systems. SUS304 stainless steel plates brazed with copper deliver maximum heat transfer in a compact, stackable design.
Why HXM
1
High heat transfer
Copper-brazed SUS304 plates give high thermal conductivity in a small package.
2
Water or glycol
Separate a glycol snow melt loop from the boiler water, or isolate any two circuits.
3
Compact and stackable
No gaskets or frames. Mounts directly in the piping.
4
Wide operating range
290 psi design pressure, -310 to 437 °F.
Simulate before you specify
HXM Heat Exchanger Simulator
Enter flows, inlet temperatures and fluids on both sides. See predicted heat transfer, outlet temperatures, pressure drop and connection velocity for all three models.

Applications
Use an HXM heat exchanger to separate two fluids that must not mix: a glycol snow melt or radiant loop from boiler water, an open loop from a closed system, or chilled water from a process circuit. Size by required heat transfer and allowable pressure drop on each side, then check the selection in the simulator.
Pair with Rhella Xtreme-Flow snow melt manifolds and hydraulic separators.
