Large Crossflow Test Cells: The Closest Bench Test to a Spiral Element

At a glance. The Tech Inc. Large Crossflow Membrane Test Cell has 140 cm² of active area and the channel geometry of a spiral element. A hydraulic holder clamps it, so membranes change in minutes.

Why bigger helps

• More permeate, so low-flux membranes are measured accurately.

• Longer channel, so concentration polarisation resembles an element.

• Standard spacers, so pressure drop and fouling compare directly.

Typical uses

Benchmarking commercial membranes, fouling and cleaning studies, and confirming lab results before element trials.

Frequently asked questions

What pressure? Up to 69 bar in SS316.

Do we need a special skid? It connects to our RO test skids and pilot units.
