Cold Aisle Containment
Deliver conditioned air directly to rack inlets with minimal bypass.
Overview
Cold Aisle Containment encloses the cold aisle so conditioned air is delivered to rack inlets without mixing with hot exhaust. It suits both raised-floor and overhead-air environments and is often the most practical option for retrofits.
Applications
- Raised-floor cooling designs
- Overhead air distribution
- Live retrofit projects
- Phased white-space expansion
System configurations
- Full-height and rack-top containment
- Floor-supported and rack-supported
- Strut-supported structures
- Fixed or removable ceiling panels
- Sliding, swing, and automatic doors
Materials & products
- Aluminium and MS framing
- Polycarbonate glazing
- Powder-coated and galvanised finishes
- Brush and EPDM sealing components
Key benefits
- Reduced bypass airflow
- Reduced hot and cold air mixing
- Temperature stability across the aisle
- Improved cooling performance
- Retrofit flexibility and scalability
DC Space scope of work
- Rack layout and airflow assessment
- Design and shop drawings
- Fabrication and finishing
- Installation, sealing, and testing
- Documentation and handover
Coordination with other services

- Trays, busways, and services above racks
HAC or CAC selection depends on cooling design, return-air path, rack density, room layout, ceiling height, fire strategy, existing site conditions, and expansion plans. DC Space reviews these factors before recommending a system.
