Facility managers who need classified cleanroom space generally face a difficult choice.
New construction requires a suitable site and can take months, even years, to complete. Depending on area requirements, installing a modular cleanroom inside an existing room is a faster, more economical alternative, but this room-within-a-room approach often creates unusable or inaccessible space.
Terra’s BioSafe Cleanroom Conversion System offers a more economical, space-efficient approach: converting an existing unclassified room into a cleanroom, using modular components to meet a wide range of environmental and access requirements.
This modular structure mounts directly to existing walls to form a drop ceiling, or rests on top of walls that have no ceiling. Its all-steel, interlocking design requires no external bracing (either column support or suspension cables) for spans up to 20 ft. (6096 mm). Larger spans entail a single internal support column or external ceiling support cable.
The grid's 2-foot x 4-foot (610 x 1220 mm) ceiling bays support cleanroom ceiling components: room-side replaceable HEPA fan/filter units (FFUs), LED or fluorescent lights, and polypropylene ceiling panels.
Terra’s WhisperFlow™ Room-Side Replaceable FFUs provide the vertical flow of micro-filtered air that removes contaminants inside the room. By selecting the proper quantity of FFUs, you can meet any cleanliness classification to ISO 5 (Class 100). Their design allows filter replacement from inside the cleanroom, without breaching the cleanroom ceiling. Lights and blank ceiling panels complete the ceiling structure. See additional information below.
Our Class A fiberglass-reinforced plastic (FRP) panel system is the only one that is certified for use in ISO 5 cleanrooms. Applied with a non-outgassing polymer adhesive to nearly any wall surface, including gypsum wallboard, this material features a patented finish that creates a durable, noncontaminating surface that is highly resistant to chemicals and microbial growth. More economical Class C panel are available (see ordering information).
CPVC (chlorinated polyvinyl chloride) Class A wall panels also meet ISO 5 requirements. A solvent-free, non-outgassing adhesive adheres them to walls. Seams are welded to close all gaps and make this system a great choice for converting current building space into a cleanroom. CPVC resists damage from a broad range of chemicals, making clean-up faster and easier.
The links below provide more information on these and other components that comprise this system, including cleanroom doors, pass-through chambers, and flooring. Installation of smooth Class A BioSafe panels, with proper wall and ceiling coving, meets stringent ISO 5-6 and cGMP requirements for the most critical applications, including sterile processing. For less critical cleanroom requirements, consider FRP Class C panels.
Whatever your applications, call Terra with your dimensional, cleanliness and other requirements. A configuration specialist will provide a complete quotation, including drawings, if applicable, and manufacturing time, on a system ready for installation and certification.
