The pipe connections can be attached to the fixed pressure plate
or to the loose pressure plate. The pipe connections on the fixed
and pressure plate are positioned as follows:
1. From the fixed pressure
plate end of the heat
exchanger looking at the
fixed pressure plate, the
connections 1F–4F are
numbered consecutively
counterclockwise. (1)
2. From the loose pressure
plate end of the heat

onto the loose pressure
plate, the connections
1L–4L are numbered
consecutively clockwise. (2)
HEAT EXCHANGER PLATES.
NOTE: The selection of the heat exchanger plate material
is determined by customer-specific operating conditions
(including pressure, temperature, media, operating mode). In
the case of some specific applications a material removal at the
heat exchanger plates by the media used is a typical process.
This can lead to a malfunction of the heat exchanger plates and
to a mixing of the media.
The heat exchanger plates and gaskets are basic components
in the plate heat exchanger. The heat exchanger plates have
horizontal and vertical corrugation patterns that are used
individually or combined. They are used for clean media with a
low viscosity and also for high working pressures.
GASKETS.
CAUTION
Damage to persons and property!
The use of pressures, temperatures and media which exceed
the original design conditions can lead to immediate failure of
the gaskets and danger to persons and surroundings. Therefore,
never exceed the original design conditions.
Warning:
Leakage
The gaskets are wearing parts and sensitive to chemical,
thermal and mechanical damage. The selection of the gasket
material is done on a custom basis for each application
based on its specific conditions (pressure, temperature,
media, etc.).
• Unintended use can lead to a reduction of the service
life. Elastomer gaskets are always subject to the aging
process (e.g. embrittlement).
Gaskets are made of elastomers, available in different materials
and shapes (e.g. 2-eye gaskets and 4-eye start and/or end
gaskets). The gaskets are normally attached without glue, but
can be attached with adhesive if requested.
All gaskets are designed to separate both media from each
other at the transfer ports by means of a double gasket guidance
system resulting in "leak ports". These leak ports divert the
leaking fluid to the outside via gaps in the gasket webs (leak
grooves), and thus make leakages identifiable immediately.
The materials of the gaskets are clearly marked by coded colors.
The storage of the gaskets must be carried out appropriately.
1. Avoid excessive temperatures, both high and low. Keep
about room temperature.
2. Avoid exposure to direct sunlight to reduce UV light
exposure.
DELIVERY, INSTALLATION, TRANSPORT,
DISPOSAL:
CAUTION
Damage to persons and property!
Improper and careless handling of the plate heat exchanger can
lead to danger to persons and property.
1. NEVER lift the heat exchanger by its tie rods.
2. NEVER lift the heat exchanger using forklift blades under
the plate pack.
3. NEVER use the connections as lift attachment points.
All of these will result in damage to the heat exchanger, and a
possible safety risk to anyone near the heat exchanger when this
is done.
DELIVERY. The fully assembled heat exchanger is packed and
delivered either lying on its side or upright, depending on the
frame type.
If it is delivered lying on its side, the heat exchanger is banded
to the pallet. A forklift can pick the heat exchanger up from
beneath the planks and transport it.
The heat exchanger that is packed upright and to be transported
upright is top heavy. It is bolted on timber planks in a manner
that is safe for transport and must be lifted from above to move
it. In no case should the device be lifted by contact with the heat
exchanger plate pack because this will damage the plate pack.
NOTE: If you notice damage to an item at delivery in spite of
careful packaging, please be sure to note the extent and type of
