The product development at Sondex has now made it possible to obtain thermal efficiency in a welded heat exchanger like a traditional gasketed plate heat exchanger.
This has been archived by transferring the technology from plate heat exchangers to the new welded range.
With this new technology within welded heat exchangers Sondex offers a range of heat exchangers working with high turbulences of the media in the heat exchanger. This then results in a high heat transfer efficiency.

The high efficiency of the heat exchangers can work with very close temperatures gabs compared to tradional shell and tube heat exchangers.
Compared to shell and tube heat exchangers the Sondex welded units, due to the high efficiency, only take up a minimum of the space and weight, needed for a shell and tube heat exchanger.  SAW07

Sondex All welded (SAW):
The SAW heat exchanger is built into a frame with its welded plate pack. The perfect solution for heat transmissions duties, which cannot be handled in a normal gasketed plate heat exchanger because of a too high design temperature, design pressure, or if there is no suitable gasket material for the media which are to be treated in the heat exchanger.

The applications for the SAW heat exchanger are the same as for the SPS heat exchanger. The only difference is that the SAW exchanger is designed to work with closer temperature approaches.
The SAW heat exchanger is designed for temperatures from -100 to 400°C and design pressures up to 4,0MPa.

Design principles:
The SAW heat exchanger contains a laser, MAG or TIC welded plate pack, in which the heat transmission pattern is pressed into each plate.
The product passes countercurrent flow through the welded plates without any change if mixing the two media.
