N-SHE2

Type 2 spiral configurations extend the spiral exchanger's self-cleaning advantage to a different flow arrangement — typically used where Type 1's configuration doesn't suit the specific combination of duty, space constraint, or flow pattern involved.

N-SPHE2 software calculates performance for this configuration specifically, rather than forcing a Type 1 approximation onto a Type 2 duty and hoping the difference doesn't matter. It handles the distinct flow path and channel arrangement Type 2 uses, producing sizing results that reflect the actual equipment configuration rather than a generalized spiral estimate.

The edge: knowing which spiral configuration genuinely fits your process is half the engineering problem, and getting it wrong means a unit that's technically a spiral exchanger but doesn't deliver the performance profile your duty needs. Our tool helps confirm the right configuration before you commit to fabrication, not after.

Where the choice between Type 1 and Type 2 isn't obvious from the duty alone, the tool flags the tradeoff explicitly — projected performance and footprint for both configurations — so you can make an informed choice rather than defaulting to whichever one you specified last time.
