GREENTUBE™ RT

The Rectangular Tube Heat Exchangers is a compact, fully welded thermal solution specifically developed for sludge-to-sludge heat recovery and biosolids treatment. This robust equipment is designed to operate without gaskets between tubes, allowing for the processing of aggressive or loaded fluids at temperatures up to 150°C and pressures of 8 bar.

Thanks to its modular design and openable version with integrated hinges, the GREENTUBE™ RT facilitates maintenance and high-pressure cleaning, even for fluids containing large particles up to 30 mm. It is a major technological driver for energy efficiency and wastewater treatment, providing maximum reliability with zero risk of leakage over time.

Main features

Main features

Energy saving

Nexson Group precise engineered thermal design allows the GREENTUBE™ RT heat exchangers to provide a high heat transfer coefficient with very viscous sludge.

Modular design

Thanks to its modular design and longitudinal format, several heat exchangers can also be placed in series or in parallel to optimize the transfer area.

Configurable

High volume flow with limited pressure drops. Very low pressure drop (<1bar).

Optimized channel geometry

Channels are designed with smooth surfaces, no cross sections reduction, and sufficient width to prevent the accumulation of debris or fouling.
