Pre-Engineered Cleanroom for USP <797> and <800>| Pharmacy & Compounding Solutions
Pre-Engineered Cleanroom for USP <797> and <800> Compliance:
A Faster, Lower-Risk Solution for Compounding, Home Infusion and GLP-1 PharmaciesNHIA 2026 Innovation Award Finalist
CE Cleanrooms’ Paragon Cleanroom System has been recognized as a finalist for the 2026 NHIA Innovation Award, highlighting innovation in sterile pharmacy and home infusion environments.
Designing a USP <797> and <800> cleanroom inside an existing facility comes with real constraints – space, structure, timelines and compliance all must align within the limits of the building.
The Paragon Cleanroom System was developed to address that reality.
What is the Paragon Cleanroom System?
The Paragon Cleanroom System is a pre-engineered, two-room sterile cleanroom platform designed for USP <797> and <800> compliance. It integrates architectural, mechanical and environmental management systems into a single coordinated solution for compounding pharmacies, home infusion providers, GLP-1 clinics and other sterile applications.
Rather than designing and building a cleanroom from scratch, Paragon provides a system that is already engineered to install efficiently, perform and maintain compliance over time.
Designed to Fit
In most projects, the biggest constraint is not the cleanroom itself. It is the building it must fit inside. The building envelope refers to the physical space within an existing facility, including height limits, structural conditions and utility access.
Paragon is designed as a free-standing system that sits within the building envelope with a 10-foot vertical clearance, allowing installation without relying on the base building structure. This reduces the need for structural modifications and simplifies project requirements.
To support different operational needs, Paragon is available in three sizes, each built on a two-room configuration (anteroom and buffer room) that aligns with sterile workflow requirements.
How Does Paragon Support USP Compliance?
Compliance is built into both the design and performance of the system. Architectural features are engineered to reduce contamination risk and support cleanability:
- Seamless pharmaceutical-grade wall and ceiling systems
- Flush doors and windows to eliminate ledges
- Reduced cracks, crevices and contamination traps
- Demarcated anteroom for proper workflow separation
The system also incorporates the new Edge coving system, which eliminates interior 90-degree corners at wall-to-wall, wall-to-ceiling and wall-to-floor transitions. This improves cleanability and helps maintain aseptic conditions over time.
Integrated Systems Designed to Work Together
Most cleanrooms are assembled from separate systems. Paragon is engineered as a single platform.Modus Mechanical System
The Modus Mechanical System manages airflow, temperature and humidity, and is designed to exceed standard compliance requirements while simplifying operation.
Key design features include:
- Reduced component count to minimize failure points
- Non-proprietary parts for easier service and replacement
- Room-side replaceable filters and external access panels
- Insulated ductwork to reduce thermal loss and prevent condensation
These features improve reliability while making maintenance faster and less disruptive.Nexus Environmental Management System
The Nexus Environmental Management System provides continuous monitoring of temperature, pressure and humidity.
It includes:
- Real-time environmental monitoring
- Local data logging and historical tracking
- Alarm systems to support compliance
- BACnet integration with building management systems
By placing sensors in the return airflow, the system provides an accurate representation of overall room conditions, supporting better operational decisions.
Pre-Engineered vs Modular vs Custom Cleanrooms
The terms modular and pre-engineered are often used interchangeably in the cleanroom industry – but they describe different things.
Modular cleanrooms refer to how a system is built. Components are manufactured offsite and assembled onsite. These systems can still be fully custom, with design work happening at the start of each project.
Custom cleanrooms are designed from the ground up for a specific facility. While flexible, they typically involve longer timelines, more coordination across vendors and greater variability during installation.
Pre-engineered systems, like Paragon, take a different approach.
Paragon is a pre-designed, pre-engineered cleanroom system manufactured using proven components and can be installed as a repeatable system.
That means:
- The system is not re-designed for each project
- The components and configurations are proven
- The installation process is consistent across sites
The result is a cleanroom that installs faster, cleaner and with far fewer surprises than traditional approaches.
Why This Matters for Cleanroom Projects
In many cleanroom builds, the biggest risks come from coordination – aligning design decisions, trades and systems during construction.
With Paragon, that work has already been done. Because the system is pre-defined and repeatedly installed, projects benefit from:
- Faster timelines with less design and coordination overhead
- Cleaner installation with minimal onsite disruption and debris
- Greater accuracy, since the system is built and installed the same way each time
- Reduced risk, with fewer unknowns during construction and commissioning
This shifts the project from a one-off build to a repeatable implementation of a proven system.
Fast Deployment Without Complexity
Traditional cleanroom construction often involves multiple vendors, overlapping scopes and extended timelines.
Because Paragon is pre-engineered and fully integrated, it reduces coordination requirements and simplifies installation. Its free-standing structure allows it to be deployed within existing facilities without extensive structural modifications. The result is a more efficient path from project start to operational cleanroom.
A Practical Alternative to Custom Cleanroom Builds
Paragon takes the experience of custom cleanroom design and translates it into a pre-engineered system designed specifically for sterile pharmacy environments.
It delivers:
- The performance of a custom solution
- The efficiency of a pre-engineered system
- The confidence of compliance built into the design
For pharmacies expanding services, entering sterile compounding or adapting to new therapies like GLP-1, Paragon provides a more predictable path to achieving and maintaining a compliant sterile environment.
FAQ: Pre-Engineered Cleanrooms for USP <797>
What is a pre-engineered cleanroom?
A pre-engineered cleanroom is a system where the design, specifications and system integration are completed in advance, rather than being developed uniquely for each project.
How is a pre-engineered cleanroom different from a modular cleanroom?
Modular refers to how the cleanroom is constructed using prefabricated components. Pre-engineered refers to how the system is designed in advance. Paragon is both modular in construction and pre-engineered in design.
What size cleanroom do compounding pharmacies need?
The size depends on workflow, volume and regulatory requirements. Paragon offers three sizes, all based on a two-room configuration, to fit a range of operational needs and building envelopes.
How does Paragon help with USP and compliance?
Paragon supports compliance through integrated design features such as cleanable surfaces, controlled airflow, environmental monitoring and proper room configuration for sterile workflows.
Can a cleanroom be installed in an existing pharmacy space?
Yes. Paragon is designed as a free-standing system that fits within existing building envelopes, reducing the need for major structural modifications.
