Nexson tube-in-tube heat exchangers are robust and fully customized thermal solutions designed for demanding processes such as sludge treatment, pasteurization, bitumen, oil & gas, etc. The technology is based on a simple and effective principle: one fluid circulates in the inner tube while the second fluid circulates in the annular space of the outer tube.
This concentric configuration allows for efficient, controlled, and sustainable heat exchange, even with highly viscous or contaminated fluids.
