Four numbers decide a brazed plate selection: the approach temperature, the plate count that buys it, the pressure drop it costs, and what the fluid does to all three.
- Approach Temperature: Approach temperature is how close the leaving temperature on one side gets to the entering temperature on the other.
- Plate Count and Capacity: Plate count is the number after the x in a SWEP designation, and it is the single biggest driver of both capacity and price.
- Pressure Drop: Pressure drop is what the exchanger costs to run.
- Glycol and Fluid Properties: Water is the fluid every rule of thumb was written for.
State the duty, not the exchanger. Flows, temperatures in and out, fluids and the pressure drop you can afford decide the frame better than any catalogue browse.
Getting the Number Right
A selection is only as good as the duty behind it. Give the flow on each side, all four temperatures, both fluids by name with any glycol concentration, and the pressure drop each circuit can spare. Leave one out and the result is a guess; with all of them it is a frame, a plate count and a quote.
