Standard Gasketed Plate Heat Exchangers

In stock
Product Details
Brand: Sondex

Recommended Applications:

The standard range of Sondex plate heat exchangers is specially designed for a range of applications in the HVAC geothermal, marine, industrial and chemical markets.

Design Principle:

The standard gasketed series of Sondex plate heat exchangers can be configured to cover a wide variety of flow rates and heat rejection requirements while maintaining connections on the head side. This will ensure easy pipe- and service work, and by dismantling the exchanger for service, no pipes need to be removed. The heat transfer is obtained, when the warm medium transfers energy through the thin, strong flow plates between the channels and delivers it to the cold opposing medium without mixing the two media. Counter-current flow creates the optimal efficiency. The plate- and inlet design allows effective, easy CIP (Cleaning in Place) of all “flow” surfaces.

Flow plates:

The corrugated “herringbone” pattern ensures turbulent flow in the whole effective area. Furthermore, this pattern brings “metallic” contact between the plates, and together with “Sonder Lock” locking devices on the gaskets, the plate pack is easily assembled. The plate pack is held firm and safely between the fixed head and movable follower of the frame.

Construction Standard:

• EN13445 (PED 2014/68/EU)

• ASME sec VIII, Div. 1


• Multiple connections available to include carbon steel with rubber lining, carbon steel with AISI 316 clading, threaded stainless steel, threaded titanium among other pipe and union connections based on the application requirements.

Plate Material:

AISI 316, 254 SMO and titanium. Also 2 x 0.4 mm “Sonder Safe” plates, for food and industry with other materials available on request.


The gasket is the unique non-glued “Sonder lock” gasket which locks the plates together with strong rubber buttons, so that the plates are strongly guided during the assembly of the plate heat exchanger. Materials can include NBR, EPDM and Viton with additional materials available on request.
