Naming of units

S9A-IG16-21-TKTL89

Type of heat exchanger:

TKTL89 - Plate grouping

21 - Number of plates in the heat exchanger

16 - Design pressure of the heat exchanger

IG - Frame type

9A – Type of heat exchanger

S – Gasketed heat exchanger

9 - … Letter S9 shows type of the attachment of gasket to plate: e.g. 9 (without A) – SonderLock 9A (with A) – Hang-on

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

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.
