1)
Type of heat exchanger:
TKTL89 - Plate grouping
21 - Number of plates in the heat exchanger
16 - Design pressure of the heat exchanger
IS - Frame type
2)
81 – Type of heat exchanger
S – Gasketed heat exchanger
81 - …
Letter S81 shows type of the attachment of gasket to plate:
e.g. 81 (without A) – SonderLock
81A (with A) – Hang-on
2)
Description of frame types:
There are few different frame types which can be offered for different applications and duties.
IS – with suspension roller,
IG – without suspension roller,
FS – food/sanitary with suspension roller,
FG - food/sanitary,
ST – simple design of frame with threaded connections
3)
Channel grouping:
In this example, the heat exchanger combines TK and TL channels. The share of TL channels equals
89% of the total number of channels.
The number of channels is defined as “the number of plates - 1”.
TK - short thermal length
TM - medium thermal length
TL - long thermal length

Connections
The heat exchanger may have connections on
both front and back-end sides of the unit.
Connections on the front-end plate are marked
with F and connections on the back-end plate
are marked with B. The numbers 1, 2, 3 and 4
designate the position of the connection on the
end-plate from the top-left port clockwise.

Using the right plate for each individual duty
is very important, as it greatly impacts the
efficiency of the entire installation.
It is important that the length of the plates and
the type of pattern match the requirements of
individual thermal duty.
We have developed a wide plate portfolio to
provide the perfect plate and connection size for
any duty.
No application is too small or too big for us - we
provide the optimal technical solution every
time.
Our extensive SONDEX® plate portfolio
includes plates that lie outside the commonly
manufactured plate sizes to cover all thermal
duties optimally.

Accessories Insulation
Recommended applications:
The insulation jacket for the plate heat exchanger
is used in different applications with high
temperatures and cooling systems.
Application Heating Cooling
Material
Outer cap
Internal insulation 0.05 mm aluminium foil
Panel fixation Plastic rivets
Temperature 20 … 200 °C -50 … -80 °C
U-value 0.55 W/m2K 0.3 8 W/m2K
Insulation class 3
Heat loss 17.1 W/m
Please note:
Inlet and outl et temperatures in the exch anger have been based on 9 0/50 – 30/70 °C.
1)
The loss of he ating/cooling is stated per m2 surface on the insu lation jacket.
The bottom o f the heat exchanger is not insu lated and this fact has been e xcluded.
A possible loss of ve ntilation, largely dep endent on the mounting of the h eat exchanger, has not been take n into account either.
Drip trays
Recommended applications:
The drip tray is available in two types. A “failsafe” solution which prevents water or liquid
from leaking onto the floor, or when the
heat exchanger is dismantled, or opened for
inspection and maintenance. And an insulated
drip tray for cooling applications, which
collects condensate formed outside of the plate
heat exchanger.
