SPIRA-CEL® Spirals

Membrane Filtration with Spiral Wound Modules based on NADIR® Flat Sheet Membranes

Spiral wound modules have a great variety of potential combinations and consequently this module type is the most common installed in filtration plants. They are used in applications ranging from the beverage, food and the pharmaceutical industry to environmental and biotechnological processes. The modules are used to separate particles like colloids, proteins and micro-organisms and to decontaminate fluids.

SPIRA-CEL® spiral wound modules – compact design

SPIRA-CEL® spiral wound modules are available with all types of NADIR® membranes (microfiltration, ultrafiltration, nanofiltration). They have a compact design and offer an optimum surface-area-to-volume-ratio.
The feed channel height can be varied by the thickness of the spacer material (from 30 to 80 mil). This allows to adapt to different levels of solids content of the liquid. This design feature leads to excellent hydrodynamics in combination with low energy demand.

A variety of module configurations for different applications

SPIRA-CEL® spiral wound modules have an outstandingly high stability against temperature and pH. They can be used to clean both caustics and acids. They can also be used in biotechnological applications where extreme cleaning conditions are required.


In addition to the commercialized SPIRA-CEL®-OX type modules (pH range of 3-14, and operational temperature of 80 °C) SPIRA-CEL®-OY type modules are also available with a pH range of 0 -12 and operational temperature of 80 °C. These module types are offered with polyethersulfone membranes in microfiltration, ultrafiltration and nanofiltration ranges.

MICRODYN-NADIR’s SPIRA-CEL® modules are readily available in different constructions depending on the area of application including process industry, biotechnology, food and dairy.
