Thermal shocks resistant – extended fatigue life heat exchanger

The spiral core provides curved shapes to the exchange surfaces that will expand -upon a sudden temperature change - in a predictable way. Consequently, thermal stresses and fatigue life can be calculated.

That is one of the most important advantage of curved surfaces compare with flat plates that will buckled in a non predictable shape.

Thermal inertia is also reduced as the gage used is as thin as 0.3 mm. Such thickness still preserves an excellent corrosion b

ehaviour.

The local containment of the internal pressure is assured by the spot welding of each contact point between the corrugated sheets. This eliminates the need for pressure vessels, end plates or tire rods as frequently used in classical heat exchangers, which always induce thermal inertia conflicts.
