SPIRAL PLATE HEAT EXCHANGERS

SINGLE CHANNEL EASY FOR INSPECTION AND CLEANING HIGH PRESSURES & TEMPERATURES

Spiral Plate Heat Exchangers - Liquid to liquid duties 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 facilitate 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. Nexson GreenSpiral™ can handle cycling duties. The robust design allows our heat exchangers to expand without...

Spiral Plate Heat Exchangers - 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 condenser mode, our SPHE offers easy access for inspections and/or mechanical cleaning on the two sides open vertical vapor media side, while the other (clean) media side is fully welded and thus is not mechanically accessible. The GreenSpiral™ Type 2 column heat exchanger unique...

Spiral Plate Heat Exchangers 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 both sided fully opened channel, through the complete width of the unit and thus creating the least amount of pressure drop. If present, our design can allow inert gases to be removed easily. The liquid media circulates in a closed spiral channel where the selfcleaning effect mitigates fouling. GreenSpiral™ Type 1BB / BW HEAT EXCHANGER The GreenSpiral™ Type 1 BB/BW (Biosolids/ Biosolids and Biosolids/Water)...

Welded plate heat exchangers - Liquid/Liquid | Biphasic Nexson GreenBox™ S is a compact welded plate heat exchanger, made of square plates welded together, forming the heat transferring plate pack heart of the heat exchanger. The heart is enclosed into a bolted frame, both hot & cold side channels are easy to access for inspection and cleaning. There are no gaskets between the plates, instead strong welds makes it leak proof. Only the four removable side pressure panels require four gaskets for external sealing. Nexson patented soft corners design makes the GreenBox™ S the most robust of its...

Welded plate heat exchangers - Liquid/Liquid | Biphasic Nexson GreenBox™ W is a fully welded compact plate heat exchanger, made of square plates welded together, forming the heart of the heat exchanger, which is enclosed into a circular shell frame. The soft corner design patented by Nexson makes this heat exchanger very robust. Due to the fully welded construction, the mechanical internal access is not possible. There are no gaskets between plates, instead strong welds makes it leakproof, designed for high pressures applications (up to 130 barg) and mainly clean media applications. This Heat...
