Rosenberg Process is a designer and manufacturer of reactor, mass transfer and separation equipment. Most of what we make lives inside a vessel — trays, valves, packing, coalescers, mist eliminators, distributors and reactor internals — the hardware that determines whether a process unit meets spec.

What sets us apart is that we do both halves of the job. Our engineers model the hydraulics and specify the internals; our own shops then manufacture and test them in England. That short loop between design and fabrication is why we can reverse-engineer a drop-in part from a sample, revamp an ageing column inside its existing shell, or build to a bespoke duty — quickly, and without depending on anyone else’s factory.

We work with process engineers, plant and operations teams, EPC firms and researchers, anywhere separation, reaction or mass transfer needs to be made better.
