Plate - corrugation and channels

L: Low theta H: High theta

We have two plate corrugations (L and H)

L + L = L channels L + H = M channels H + H = H channels

These form three different channels (L, M and H)

We choose between L, M and H channels Tailor-make it for the specific duty


11/37

Plate - corrugation and channels

Advantages

Efficient heat transfer High wall shear stress

Variable thermal length

Strong construction

Benefits

Increased heat recovery Low fouling

Optimal design

Insensitive to vibration

Low turbulence& pressure drop

L + L = L channels

Medium turbulence& pressure drop

L + H = M channels

High turbulence& pressure drop

H + H = H channels


12/37

Plate - materials Standard materials and thicknesses

AISI 304 (stainless steel)

Usually 0.4 or 0.5 mm thickness

Cheapest possible solution

AISI 316 (stainless steel)

Always 0.5 and 0.6 mm

Some with thicker plates (high-pressure applications)

254 SMO (high-alloy stainless steel)

Usually in 0.6 mm to allow stock-keeping

Titanium

Always 0.5 and 0.6 mm

Some with thicker plates (high-pressure applications) Some PHEs with 0.4 mm (low-pressure applications)

Alloy C-276 (Nickel alloy)

Usually in 0.6 mm to allow stock-keeping

Plate - materials Standard materials and typical uses

AISI 304

Typically in clean water-water duties

Example, up to 50 ppm chlorides at 50C

AISI 316

Typically in water-water duties


254 SMO (high-alloy stainless steel)

Many uses including high-chloride water-water duties


Titanium

Most frequent use is for sea water (3.5% chlorides) Example, up to 130C in sea water

Alloy C-276 (Nickel alloy)

Most frequent use is for concentrated sulphuric acid up to 90C

Gasket - advanced sealing system

Long lasting gaskets!

...or glue-free gasket

that do not mix sealingand fastening function

Gasket - profile and groove

Risk of leakage.

Full support

gasket blow-out.

The difference is life time and reliability


16/37

Gasket - double sealing systemSpecial venting ports are an integral part of the gasket

design to prevent cross contamination

If the gasket failsLeakage is detected on the outside


17/37

Gasket - glue free fastening

Fastening and sealing are kept separate

If the one of the fastener breaks, the gasket still stays sealed

Clip-on is mostly used (snap-on on a few older models)

Gasket - glued versus glue-free

Should be the choice of the customer

...BUT glued is preferred:

On large plates

When units are opened frequently

On high pressure duties

When the gasket will be swelling due to chemical attack
