OLTREMARE
Oltremare is a MANN+HUMMEL RO membrane product line covering low-pressure compact and XL elements, brackish-water, seawater, and low-fouling elements.It is relevant where light industrial, domestic, brackish, marine, and challenging feed applications require compact spiral-wound membrane families with defined replacement sizes.
OLTREMARE's position in RO/NF membranes and related equipment is defined by product families such as RO, NF, UF-adjacent membrane elements, membrane contactors, pressure vessels, housings, and related separation products.
The portfolio is best understood inside brackish water, seawater desalination, ultrapure water, process separation, reuse, degassing, and membrane system packaging, where engineers compare the technology route, family boundaries, and duty fit before narrowing to individual models.Representative series on this page include AsHR-2540, AsHR-4040 and AsHR-8040.Engineers should compare element size, salt rejection, permeate flow, pressure rating, fouling resistance, connection type, and vessel fit.
