Stainless Steel Membrane Housings

The Helpful Heat Exchanger Experts

Filtration System suppliers rely on Enerquip to provide safe, durable, sanitary pressure vessels as housings for their membrane cartridges. Whether they are filtering using a reverse osmosis (RO) process or other multi-stage filtering system, they appreciate the consistency and tight fit-up tolerances of Enerquip fabrication.

One of the most important components to a reverse osmosis system process is the membrane housing. Storing and protecting the membrane, our stainless steel housings are rigorously designed and manufactured to withstand the high pressures required for reverse osmosis.

Enerquip can code stamp membrane housings per ASME, and is one of the only suppliers of membrane housings with CRN certification for Canada.

Enerquip’s durable, stainless steel membrane housings do not warp or weep like fiberglass membrane housings. They are able to withstand temperatures up to 200º F during cleaning cycles, and are a great option when sanitation is critical.
