Heat exchangers

GREENBOX™

GREENBOX™ is a fully Welded Plate Heat Exchangers (BLOC), made of square corrugated plates welded together, forming the heart of the heat exchanger. There is no gasket between the plates; the waterproofness is done by a weld. Only the removable side panels have gaskets for external sealing.

The heart of the heat exchanger is accessible for inspection or cleaning by simply removing the 4 side panels. The patented soft corners design, (the heart / panels assembly), makes this heat exchanger the most robust of its category and is the ideal solution for operation in tough process duties with high pressures and temperatures.

He is a concentrate of thermal efficiency as heat recovery interchanger, condenser, reboiler or evaporator, and can be used in fouling duties.

High turbulent flow induced by the corrugated plates of GREENBOX™ makes it about 5 times more thermally efficient than a traditional shell & tube heat exchanger. It also allows a temperature approach of 2°C.

A better heat transfer coefficient means also compact size and this can also reduce significantly installation, operation and maintenance costs.

Ingenious corner’s design brings mechanical reliability to the heat exchanger.

The GREENBOX™ works in simple or multi-pass and, if needed, the access to the plates for inspections and cleaning is given by simply removing the side panels.

He is used for a design pressure from full vacuum to 50 barg, from -50°C design temperature to 450°C.

Main features

Main features

Compact size and easy installation

Nexson welded heat exchangers are very compact units. They require a very small floor space including the space needed for installation and maintenance.

Maximised heat transfer coefficient

Nexson's plate are designed with high shear stress, coupled with a high turbulent regime. This will optimise the efficiency of the heat exchanger while reducing any risks of fouling.

Close temperature approach

The unique corrugated plates design allows the welded heat exchangers to reach a very close temperature approach and even get to crossover temperature by achieving high heat transfer K coefficient values.

Interchangeable heart

Thanks to its modular construction, we can remove parts that need to be replaced by new parts and at the same time keep the parts in good condition.
