SONDEX® gasketed plate heat exchangers are
the ideal choice for a wide range of applications
across numerous market segments.
We have the largest plate portfolio in the
world, and we customize each heat exchanger
to meet your exact requirements. Innovative
technologies and smart design make our
gasketed plate heat exchangers a stellar
investment.
Benefits:
• Individually customized solution that
perfectly matches your requirements and
lowers your energy consumption.
• High performance and a low pressure
drop eliminate unnecessary burdens on
your system and optimize overall system
performance.
• The design results in a compact solution with
a small footprint, simple installation, and easy
access for maintenance.
Common applications:
• HVAC industry
• Marine/offshore industry
• Dairy/food/beverage industry
• Sugar industry
• Biogas industry
• Pulp and paper industry
• Heavy industry
• Mining industry
• Petrochemical industry
• Chemical industry DN 200
Main data:

Approvals:
• Please contact your local Danfoss/SONDEX®
sales representative for an overview of the
available approvals in your region
43 - …
Letter A shows type of the attachment of gasket to plate:
e.g. 43 (without A) – SonderLock
43A (with A) – Hang-on
AD - wider channel gap design
TY - asymmetric channel design

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.
The insulation jacket for the plate heat exchanger
is used in different applications with high
temperatures and cooling systems.

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
