CRS CEILING SYSTEMS

CRS manufactures, supplies and installs strut-framed metal pan ceiling systems for data centres, designed to deliver optimal operational flexibility and containment efficiency, and engineered to support other requirements, including cable management and fire suppression.

All ceiling tiles are manufactured from high-quality galvanneal sheet, preventing any risk of zinc whisker contamination, and ceiling tiles are finished by powder coating to specific colour requirements.

We deliver additional value through the customisation of ceiling tiles to include penetrations for mounting of other services, and can supply an extensive range of customised tiles for installation in specific locations across complete data centre areas, including cut-outs for recessed luminaires, which can deliver superior illumination results.

Penetrations for mounting a range of environmental BMS sensors can also be provided, reducing upfront procurement and installation costs, and providing an aesthetically superior solution.

Provided relevant information can be secured prior to final manufacture, we are happy to provide penetrations, and will take the lead in coordinating with other trades to confirm required sizes and location details.

CRS CEILING SYSTEMS KEY FEATURES & BENEFITS

  • No turnbuckle or reverse threaded rod sections are required.
  • Indexing notches located at fixed intervals on main grid extrusions for accurate location of connection brackets.
  • Grid extrusion incorporates an underside channel for the insertion of fastening nuts which provide exceptional pull out resistance and connection reliability for robust fixing to the ceiling.
  • Attachment of preassembled ceiling sections to threaded rods simplified with innovative bracket design that hooks onto rod spindle, ie no fiddly connection to turnbuckles.
  • Fasteners do not leave permanent paint damage to underside of channel improving aesthetics over life-cycle of ceiling.
  • Design allows for seamless integration around standard penetrations.
  • CRS Ceiling Systems are the optimal choice for applications where complex and concentrated overhead services are required including lighting, cable trays, fibre duct, fire protection, and power busways.
  • CRS ceiling systems allow for extremely rapid installation times providing extensive cost benefits over the more traditional & cumbersome structural ceiling systems.

CRS Data Centre Ceiling Features

Airflow Management & Aisle Containment

Air flow delivery from or return to the plenum space can be provisioned for by the use of grilles that can be readily installed in the ceiling grid where required for instance above hot aisles. Air grilles with adjustable opposed blade dampers are also available for applications where modulation of return air flow is required.

CRS Data Centre Ceiling Tile Details

CRS ceiling tiles are made from a single formed metal sheet to an engineered profile that enhances seal integrity and ready access removal. All ceiling tiles are manufactured from electro gal or equivalent sheet metal guaranteeing inherent corrosion resistance and prevention of zinc whiskers. Available in a range of nominal pan sizes such as 1200 x 600mm to suit all common grid configurations. CRS also provide a range of base sheet metal thickness including 0.7mm, 0.9mm and 1.2mm with powder coated finish to align with applicable differential pressures. Perimeter seals can also be provided where extremely high containment integrity is required.

Joint Sealing

CRS ceiling systems are sealed against air leakage into the ceiling plenum using a purpose designed self-adhesive foam seal strip. The foam strip is applied on all perimeter sides of the ceiling tile to ensure it seals effectively into the ceiling grid. Tape will overlap sufficiently at ends so that adequate seal density is achieved in corners.

Dacta Centre Ceiling Trimming Detail

To ensure the effectiveness of the ceiling across the full installation area, grid framing and ceiling tiles can be readily adpated as necessary to ensure the ceiling containment plane is preserved. Careful design consideration has been given to real world data centre applications and as such the CRS ceiling design allows for seamless integration around standard penetrations for the following;
• Environmental sensors
• Annunciators
• Fire detection & suppression
systems
• Cable trays & managers
• Light fittings etc
