Modular Hard Wall Cleanrooms

Now any company can meet ISO and Federal Standard 209 Cleanliness requirements cost effectively with minimum delay. CRD Clean Rooms are pre-engineered to any size or configuration and can be designed from Class 10 (ISO 4) to Class 100000 (ISO 8). Ante Rooms are offered for gowning and air lock purposes.

All modular, rigid-construction components are designed for convenient installation. The heart of the Modular Hardwall is the filtration method. Using 2′ x 4′ HEPA Fan Module or Ducted HEPA Modules with a filter efficiency of 99.99% on particles 0.3 microns or optional ULPA Filters at 0.12 microns. Both types of filters are integrated with air conditioning system

Rapid Installation

Wall panel systems come in standard 4′ wide sections with various materials to chose from. Once the floor track is secured, the wall panels are erected in minutes by locking in place to wall studs and trim pieces. Window and wall penetration options are already installed, precut and framed.

Leak-Free Ceilings

Ceiling components consist of specially designed high-efficiency fluorescent lights, CRD Clean Flo-4 HEPA Filters and Class 100 ceiling tiles are supported by “T” grid system. When these components are sealed or gasketed into the “T” grid they form a leak -free ceiling system.

Design Versatility/Multi Zone Cleanliness

Critical Operations are conducted below HEPA/ULPA Modules located wherever you choose. The clean air flows downward over the work surface and out of the room through the single pass transfer grilles or can recirculate through wall returns and ceiling plenum space. Clean Room Depot will recommend locations consistent with your room layout.

Hinges to be 1 1/2″ pair 4 1/2″ x 4 1/2″. Lockset to be commercial quality key-in-knob type. Mill finish, painted aluminum.

4.0 Ceiling
Ceiling consist of 2’ x 4’ recessed light fixtures, 2′ x 4′ Motorized or Ducted Filter Modules, Class 100 Ceiling Tiles and extruded aluminum or painted steel “T” grid designed specifically for clean room application. The number of Lights, HEPA filters and Ceiling tiles will vary as a function or room size and class.

5.0 Filtration
Clean Room filtration provided by CRD’s Clean Flo-4 HEPA Filter Module measuring 23 5/8″ x 47 5/8″ x 12″. Filtration to be 99.99% @ 0.3 microns with 20% efficient pre-filter variable speed motor, rated for full load 1.8 Amp and UL listed or LCH-4 Ducted Filter Module.

Standard options to include a duct collar for direct connection to client air conditioning, magnehelic gauge, ULPA filtration and 220 Volt operation. Careful consideration should be given by the specifier/AC Designer, as flow requirements for cleanliness and air conditioning often vary greatly.

A well-conceived, properly administered maintenance program is a requirement for an efficient clean facility. The effectiveness of this maintenance program can be measured by regular testing of the facility by a Clean Room Depot technician.

A program of periodic inspection can be established on a quarterly, semi-annual basis. A customized testing program can be developed from the menu of tests presented below. Once a program has been initiated, the scheduling of on-site testing will be accomplished automatically.

The aim of the testing program is to monitor facility performance to identify significant changes in efficiency. Such changes can be addressed before they become a major problem resulting in decreased product quality or unplanned facility downtime.

During a typical certification test, the technician will identify areas of concern and make the client aware of them. Adjustments will be made as necessary to bring the room into compliance with client standards and/or other pertinent standards. Recommendations and cost estimates for procedures necessary to bring the facility into compliance will also be offered. Upon completion of the test procedure, a Certificate of Conformance and supporting test report will be submitted to the client.

Typical Test and Procedures per ISO Requirements

  • Cleanliness levels per ISO and Federal Standard 209
  • Particle size and quantity count
  • Temperature control range test
  • Humidity control range test
  • Filter pressure drop measurements
  • Air flow quantity measurements
  • Air flow velocity measurements
  • Noise level checks
  • Light level checks
