Nexson Group products

Thanks to its specific design, the liquid to liquid heat exchanger can handle one or two fouling fluids. Both channels are easy to access for inspection and cleaning. Your alternative to the shell and tube heat exchangers !

Sludge spiral heat exchangers are specially designed for digester sludge heating and heat recovery applications, such as digested sludge heating, raw sludge heating and heat recovery from effluents, pasteurisation, methanisation.

The vapor circulates, cross flow, in a fully opened channel, with negligible pressure drop and the coolant circulates in a closed spiral channel. Thanks to its versatile design, it can be directly installed on the top of a column/rector without any supporting system, reducing quite much installation costs. It is perfectly suitable for vacuum condensation with negligible pressure drop. It can be used as vent condenser.

Thanks to its specific design, the liquid to liquid heat exchanger can handle one or two fouling fluids. Both channels are easy to access for inspection and cleaning. Your alternative to the shell and tube heat exchangers ! This SPHE model is specifically designed to handle up to 200 barg / 450°C for tough applications.

The vapor circulates, cross flow, in a fully opened channel, with negligible pressure drop and the coolant circulates in a closed spiral channel. The column is made of several spiral heat exchanger welded in series in the same shell to achieve large condensing duties. It is perfectly suitable for vacuum condensation with negligible pressure drop.

Able to work in extreme conditions (of pressure and temperature), this single channel heat exchanger, with self-cleaning effect, has become the alternative to the shell & tube exchangers. More compact and until 3 times more thermally efficient, the Spiral Plate Heat Exchanger gives the possibility to do substantial savings in installation, operation and maintenance.

High turbulences and strong mechanical capacity. Robustness , reliability for welded block heat exchanger is the key point. Nexson has patented his own welded block heat exchanger, named GreenBox ™. With proven pressure and temperature cycling tests, this type of heat exchanger is one step ahead the competition in terms of robustness.

Welded heat exchanger with “baffles” for condensing / evaporation.
