1. DESCRIPTION OF THE FILTER

Each double filter is composed of two filter housings, (one working and the other in stand-
by), linked by means of a double 3ways transfer valve to switch the housing without stop the
system.

Inside each housing there are one or more filter elements.

Basically there are two different types of filter element in function of the filter material.

a. Re-usable filter element : Usually the filter material is stainless steel mesh. These
filter elements can be cleaned if they are clogged, and re-used again.

b. Non Re-usable filter element: The filter material is usually paper or inorganic
fibber. These filter elements must be thrown out.

2. INSTRUCTIONS TO OPEN A HOUSING AND EXTRACT THE

FILTER ELEMENT.
a) Check the differential pressure switch indicates the filter is clogged.
b) Check with the handle or the wheel of the valve what is the filter in operation.
c) Open the purge fitting at the cover of the housing in stand-by.

d) Open the manual valve to equilibrate pressure in each housing. The stand-by
housing will fill with oil.

e) When the housing in stand-by will be completely filled of oil, the oil will start to flow
throw the air purge fitting. Close it quickly and be sure there is no air inside the filter
housing.

4.3.3 Gaskets for GC and GF plates

This range of plates has the gasket groove in the

plate’s bottom plane. Each plate is glued with one
full thickness gasket on the front side. The first
plate is glued with a full thickness gasket that has
rings at all port holes.

One complete set of gaskets comprises of one (1)

four ring gasket and x full thickness gaskets, x =
number of plates -1.

It’s important to follow the gluing instruction

from the plate sequencing specification sheet, see Four ring gasket LU. The rings are to the
Section 5.1. Gaskets are always viewed as being Left and chevron is pointing
glued to the front face of a plate. Up.

4.3.4 Gaskets for GW-plates

Plate pairs are welded together to form a sealed channel

or element. In order to close off or seal two of the four
portholes in the element, a laser weld is extended
diagonally in front of the two vertically aligned ports.
Refrigerant (or corrosive fluids), which enters the sealed
channel through the inlet port, flows inside the element.
Special designed, double ring gaskets are placed on
either side of the inlet and outlet ports, thereby creating a
seal around the ports. Perimeter gaskets (also referred to
as Parallel Gasket) are placed on either side of the
element, creating a sealed envelope to contain the
process fluid. The process fluid flows between the
elements in the gasketed channel.

It’s important to follow the gluing instruction from the

plate sequencing specification sheet, see Section 5.1.

Parallel gasket Ring gasket

Double ring gasket will decrease the rate of

permeation from low level to zero.

10. Trouble shooting

10.1 Rectifying a leaking PHE

10.1.1 General

Measure the A-dimension (plate pack thickness) at several points around the plate pack. Compare with
theoretical value.

Check that the covers are parallel and not drawn out of alignment.

If a PHE is leaking, it is important to localize the leak before the unit is dismantled, otherwise it often becomes
more difficult to rectify the problem.

To rectify a minor leak, it may be sufficient to tighten the unit a bit further. Ensure that the plate pack is not
tightened below the minimum A-dimension.

10.1.2 Localizing the leak

The unit should be inspected thoroughly on all sides

including top and bottom of the plate pack. Pinpoint all
leaks by counting the number of plates from a cover
and by accurate measurements. If possible, connection
ports that are not under pressure should be inspected
for leaks.

a) Through the gasket leakage groove (from the

area between ring and diagonal gasket).

b) Through an external gasket on the side of the

plate pack.

c) Internal leakage.

d) Leakage at the nozzle lining.

A. Leakage through the gasket leakage groove

The most common reason for this type of leakage

is gasket failure, either the ring or the diagonal
gasket.

If the gaskets are in good condition and correctly

located in the gasket grooves, check for possible
corrosion in the areas between the ring and
diagonal gasket by visual inspection or dye
penetration.

B. If a external leakage occurs on the side of a plate pack at any position excluding the ones described in
picture 1.1 above, during operation, this may have the following causes:

- Inadmissible high pressure or temperature. Check operating pressure and temperature. Correct if
necessary.
- The compression (A dimension) is incorrect. In this case, shut down the PHE and tighten gradually in its
unpressurized state. Do not go below minimum A dimension. The A dimension must not vary by more
then 2 mm at different measuring points.
- Incorrectly positioned or damaged gaskets. Check the gasket and its location in the gasket groove for
foreign particles that might jeopardize the integrity of the seal. Replace damaged gaskets and if
necessary correct the position of the gaskets.

C. If there is an internal leak in a plate heat exchanger, the reason is probably a hole/crack in a plate caused by
corrosion or mechanical damage. To localize this type of leak, it is necessary to disconnect one of the lower
connections, pressurize the other side and observe where the drops come from.

Note that it may be necessary to switch sides to find the hole or crack. Measure the distance from the cover
to the leak to determine which plates are suspected. Remove and check these plates visually and by dye
penetration.

D. If a leak occurs adjacent to a frame cover near a port, the reason could be:

• Cracks in the metal liner results in leakage between the cover plate and the liner. If this occurs on the
inside of the cover, it is often easy to see.

• If it occurs on the outside of the cover, it can sometimes be difficult to see the difference between this
and a leaking gasket for the connection flange.

• The ring gasket on the first plate not sealing

correctly to the liner can also cause a leak at
the cover inside.

If this is due to incorrect centering of the

liner/ring gasket, it can be remedied by
adjusting the carrying bar. In certain cases, it
may be possible to adjust the liner somewhat
by moving it sideways in the cover porthole.

Graph readings apply to water at 68° F (20° C). They result from
Volumenstrom / volume flow w [m3/h]

messurements on valves installed in horizontal pipes.

For installation in vertical pipes insignificant devitations occur
in the partial opening. In order to determine pressure losses for
other media the equivalent water flow has to be calculated before 10
