Spiral Plate Heat Exchangers

[a.diegomaradona]

Hy guys !!
Is there any standards for thermal designing of spiral plate heat exchangers, like TEMA for shell and tube heat exchangers ?

ISO 12211 Petroleum, Petrochemical and natural gas industries - Spiral Plate Heat Exchangers

There is also a draft API standard that is identical but not officially released yet.

I guess I should be more specific. ISO 12211 is not specifically a thermal design spec for spirals (just like TEMA is not specifically a thermal design spec for shell and tube heat exchangers) but it does have some useful information on configuration of the different construction methods and some examples on clean heat transfer coefficients and recommended fouling margin.
