Nexson - Model Type 1 -Spiral Liquid Duties Plate Heat Exchanger

The spiral design and optimization of conditions in both channels of the Nexson spiral heat exchangers provide a high heat transfer value (K value) which leads to big savings in energy costs.

Nexson spiral heat exchangers are designed to maximize heat transfer surface. They can be set up vertically or horizontally with no need for complex installation. In addition maintenance costs are very limited.

Regarding the liquid to liquid duty, one Nexson spiral heat exchanger can replace 3 traditional Shell & tubes products, releasing footprint for the process part.

Thanks to the single channel configuration, a turbulent flow is created to handle tough medias. Since it is a single channel heat exchanger, if there is any cross section reduction inside the channel, flow velocity will increase flushing out the deposit.

Thanks to its defined cross section uniform from the beginning to the end of the spiral core combined with turbulent flow,  the spiral heat exchanger technology is considered as a no dead zone heat exchanger in the channel flow.

Nexson spiral heat exchangers can be either customized or you can go for standard models. The standard range gives you the opportunity to discover the spiral heat exchanger technology at a very limited cost and with a short delivery time while offering similar quality and a made in France production.

Access and inspection of the whole heat transfer surface is facilitated thanks to openable end covers.

Nexson spiral heat exchangers are designed to handle suspended fibers / particles in the media. When it comes to erosive and / or corrosive medias, we propose some adapted features to handle it.

Nexson spiral heat exchangers provide the possibility of medias temperatures approach around 3°C.

The heat transfer area available for a liquid to liquid exchanger fluctuates from 2 to 700m².
