Nexson Group Process Systems
Type 1 liquid-liquid
GreenSpiral™ versatile design allows it to handle one or two fouling fluids. Our customized, fit for purpose approach, optimizes the channel spacing vs particle size, and the pressure drop across each channel. The single passage channels facilitates turbulent flows to handle fouling medias and have a self-cleaning effect. Both channels are easy to access for inspection and cleaning. Your alternative to the shell and tube heat exchangers.

Type 2 biphasic applications
Nexson GreenSpiral™ Type 2 heat exchanger is ideal to handle biphasic applications where condensing is required for vapors, with or without inert gases, evaporation of large flows and when low pressure drop is required, such as near vacuum applications. In evaporator or condensermode, our SPHE offers easy access for inspectionsand/or mechanical cleaning.

Type 3 – Steam heater
GreenSpiral™ Type 3 plate heat exchanger is commonly used to heat a fouling, viscous, tough fluid medias by using steam. The steam circulates in a crossflow manner in a fully opened channel, through the complete width of the unit. If present, our design can allow inert gases to be removed easily. The tough media circulates in a closed spiral channel where the selfcleaning effect mitigates fouling.

Type 1 – Environment
The GreenSpiralTM Type 1 BB/BW (Biosolids/Biosolids and Biosolids/Water) is specifically design to handle highly fouling sludges in the Biogas and Waste Water treatment applications.
GreenSpiralTM Type 1BB / BW plate heat exchangers are specially designed for digester sludge eating and other heat recovery applications like raw sludge heating and heat recovery from effluents, pasteurization and/or methanisation.

Thermowave
Gasketed plate heat exchangers
Thermowave products versatile are designed to optimise heat exchange between fluids, offering unmatched performance and reliability.
The gasketed plate heat exchangers are engineered with precision, featuring individually stamped heat transfer plates with gaskets around each plate. This innovative design ensures a tight seal, preventing leaks and maximizing heat transfer efficiency.
Investing in gasketed plate heat exchangers can lead to significant cost savings over time.

Semi-welded Plate Heat Exchangers
thermowave products semi-welded plate heat exchangers combine the reliability of welded construction with the versatility of gasketed plates, offering unparalleled performance in a variety of applications.
Semi-welded plate heat exchangers feature a unique design that incorporates both welded and gasketed plates. This hybrid construction provides a secure seal for one fluid stream while allowing for easy disassembly and maintenance of the other. The result is a durable and efficient heat exchanger that can withstand demanding operating conditions.

Double Wall Plate Heat Exchangers
Our double wall plate heat exchangers (DWHEs) are a vital innovation for industries that demand flawless fluid separation and efficient heat transfer. Whether used in food and beverage production, pharmaceutical manufacturing, or chemical processing, our exchangers ensure superior safety and unmatched reliability. Our double wall plate heat exchangers prioritize safety with an extra barrier between fluids, reducing the risk of cross-contamination. If a leak occurs, the fluid is directed into the intermediate space, preventing mixing. This design makes leaks visible, enabling prompt maintenance and minimizing operational risks.
