Paul Industries is a single-source process-equipment and sanitary-piping contractor that designs, fabricates, installs, and validates the systems biotech and biopharmaceutical manufacturers depend on — bioreactors and fermenters, WFI and high-purity water, CIP/SIP skids, cleanrooms, and single-use system integration. With more than 30 years of cGMP/FDA-compliant work across the US East Coast (NJ, NY, PA, DE, MD, CT), we handle upstream and downstream process systems from concept through IQ/OQ/PQ under one accountable contract. One vendor owns the mechanical scope, the documentation, and the schedule.

Process systems we build for biotech & biopharma
Biologic manufacturing lives or dies on the integrity of its process systems. Unlike small-molecule chemistry, biologics are produced by living cells, so the equipment train has to protect a sterile, contamination-controlled environment from the seed train all the way through final fill. Paul Industries builds the mechanical backbone of that train for facilities across the East Coast biotech corridor — from New Jersey and the greater New York region through Pennsylvania, Delaware, Maryland, and Connecticut.
On the upstream side, that means installing bioreactors and fermenters — whether single-use assemblies or stainless-steel vessels — along with media and buffer prep skids, the sanitary transfer piping that connects them, and the clean utilities that feed them. On the downstream side, we handle the piping and skids for harvest, clarification, chromatography, filtration, and tangential-flow steps, plus the CIP/SIP systems that keep stainless trains clean and sterile between batches. Underlying all of it is high-purity water — WFI and purified water generation, storage, and hot-loop distribution — and the cleanroom envelope that surrounds aseptic and cell & gene therapy operations. Because we self-perform the mechanical scope and coordinate validation as one contract, the interfaces between these systems are engineered together rather than negotiated between separate trades on site.
Single-use vs. stainless-steel systems
One of the first architecture decisions a biotech facility faces is how much of the process to run on single-use (disposable) technology versus fixed stainless steel. We install and integrate both, and the right answer usually depends on scale, product mix, and how often the facility changes products. The table below outlines the practical trade-offs we help clients weigh.
| Consideration | Single-use (disposable) | Stainless steel |
|---|---|---|
| Best suited for | Multi-product suites, clinical & early commercial scale, cell & gene therapy | High-volume, dedicated large-scale commercial production |
| Cleaning & sterilization | Pre-sterilized, discarded after use — no CIP/SIP required | Requires validated CIP/SIP systems and cleaning cycles |
| Cross-contamination risk | Low — closed, disposable flow paths reduce changeover risk | Managed through validated cleaning and sterilization |
| Capital & utilities | Lower up-front capital and clean-utility demand | Higher capital; larger WFI, clean steam, and CIP demand |
| Key installation focus | Extractables/leachables review, tubing management, assembly integration | Orbital-welded sanitary piping, slope, drainability, passivation |
| Changeover flexibility | Fast product turnover — swap disposables between campaigns | Slower — cleaning validation between products |
Many modern facilities are hybrids: single-use bioreactors upstream feeding stainless downstream utilities, or the reverse. We routinely integrate both in the same suite and make sure the clean utilities, piping, and instrumentation are sized for the combined load.
What we build / services
- Bioreactor & fermenter installation — single-use and stainless-steel vessels set, connected, and integrated with utilities, media/buffer prep, and controls.
- High-purity water systems — WFI, purified water, and clean-steam generation, storage, and sanitary distribution loops built to hold quality at the point of use.
- Cleanrooms — ISO 14644-classified suites for aseptic processing, fill-finish, and cell & gene therapy, with the mechanical and utility systems that support them.
- CIP/SIP systems — clean-in-place and steam-in-place skids and piping that deliver repeatable, validatable cleaning and sterilization for stainless trains.
- Sanitary process piping — orbital-welded, drainable stainless piping fabricated and documented to ASME BPE for product and clean-utility service.
- Validation & commissioning — IQ/OQ/PQ execution, turnover packages, and documentation coordinated alongside the mechanical work, not bolted on afterward.
Standards & compliance
- cGMP / 21 CFR Part 211
- The FDA’s current good manufacturing practice regulations set the baseline for how drug products — including biologics — must be made and documented. Our installations are built and documented so equipment, utilities, and materials of construction support a facility’s cGMP obligations.
- ASME BPE (Bioprocessing Equipment)
- The industry standard for sanitary process systems. It governs surface finishes, weld quality, drainability, and material traceability for product-contact piping and equipment. We fabricate and install to BPE so systems clean out, drain fully, and hold up to repeated sterilization.
- ISO 14644
- The cleanroom classification standard that defines airborne particle limits by class (for example ISO 5 for aseptic filling). It drives the design of the cleanroom envelope and the utility systems we install to hold that classification in operation.
- Single-use / extractables & leachables
- Disposable flow paths introduce polymer components into the product stream, so their extractables and leachables profile matters. During single-use integration we account for compatible materials, assembly integrity, and the documentation clients need to support their own E&L assessments.
- IQ/OQ/PQ
- Installation, Operational, and Performance Qualification are the staged protocols that prove a system was installed correctly, operates within specification, and performs reliably under real process conditions. We execute and document these steps as part of commissioning so the system is inspection-ready at turnover.
Why Paul Industries
Biotech projects fail at the seams — where the water system meets the bioreactor, where the piping contractor hands off to the validation team, where the cleanroom trade blames the mechanical trade for a missed spec. Paul Industries removes those seams. As a single-source contractor, we own design, fabrication, installation, and validation coordination under one contract, so there is one team accountable for the whole process train and one set of documentation that ties it together. More than 30 years of cGMP/FDA-compliant work means we understand that in a regulated facility the paperwork is part of the deliverable, not an afterthought. And because we are based on the East Coast and serve NJ, NY, PA, DE, MD, and CT, we can respond quickly for tie-ins, shutdowns, and support work without flying a crew across the country. We describe our capabilities honestly — what we can build and how we build it — and let the work speak for itself.
