Naming of units

S21A-IG16-21-TKTL89

TKTL89 - Plate grouping 3)

21 - Number of plates in the heat exchanger

16 - Design pressure of the heat exchanger

IG - Frame type 2)

21A – Type of heat exchanger 1)

S – Gasketed heat exchanger

1) Type of heat exchanger:

21 - …

Letter A shows type of the attachment of gasket to plate:

e.g. 21 (without A) – SonderLock

21A (with A) – Hang-on

SE - SonderLock Energy Saving plate design

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.

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

	Material		Not flammable
					DIN 4102-1 B2
			DIN EN 4102A2
	Outer cap			1 mm aluminium
				“Stucco” Embossed

	U-value		0.55 W/m2K		0.38 W/m2K
	Insulation class		3 1)		4 1)
	Heat loss		17.1 W/m2		-

Please note:

Inlet and outlet temperatures in the exchanger have been based on 90/50 – 30/70 °C.

1)The loss of heating/cooling is stated per m2 surface on the insulation jacket

The bottom of the heat exchanger is not insulated and this fact has been excluded.

A possible loss of ventilation, largely dependent on the mounting of the heat exchanger, has not been taken 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.

Materials

Drip tray consists of:

•1 mm galvanized steel frame

•Hanging brackets in galvanized steel

•60 mm Polyurethane insulation for cooling applications

•Draining valve.

Spare parts

Spare parts for gasketed heat exchangers, such as plates, gaskets, frame parts can be ordered for maintenance, repair, increasing heat exchanger capacity, etc.

Please contact your local Danfoss or SONDEX® sales representative to provide you with information on spare parts available for gasketed heat exchangers.

Selection and ordering	Please contact your local SONDEX® or Danfoss
	sales representative for the selection and / or
	ordering of the heat exchangers, spare parts, and
	accessories.
