Pre-assembled doors are designed to be installed and functional within minutes.

The Cool Shield Single Sliding Door system is highly functional and cost-efficient for aisles up to 50” wide. Both the doors and frame have the sturdiness to stand up to years of functional service.  The simple and efficient design has few parts and requires minimal maintenance for low cost of ownership. The adjustable hydraulic self-closing mechanism ensures doors close after aisle entry to prevent air leakage.  A magnetic hold open feature allows equipment to be brought into the aisles.

Cool Shield Single Sliding Doors work great for narrow aisles and single row aisles next to a wall. An optional side light frame can be added to span distances greater than 50”.  Doors arrive fully assembled for quick and on-site installation. The Cool Shield door frames, like all Cool Shield extrusions, feature a combination of threaded and slotted channels for multiple mounting and sealing options. Doors are pre-assembled at our factory to minimize labor required for the onsite installation.

    • Sliding doors in aisle containment refer to a type of door system used in data centers or server rooms to enclose hot or cold aisles.
    • The primary purpose of sliding doors in aisle containment is to optimize airflow management and improve energy efficiency within the data center.
    • These doors are designed to seal off the aisles completely, preventing air leakage and mixing between hot and cold zones.
    • Sliding doors typically have a modular construction, allowing them to be easily installed or removed as per the requirements of the data center.
    • They are often made of sturdy materials such as steel or aluminum to provide durability and security.
    • Sliding doors may feature transparent panels, allowing visibility into the aisle while maintaining the seal and ensuring easy monitoring of equipment.
    • The doors are equipped with smooth sliding mechanisms, enabling easy access to the aisles when necessary for maintenance or equipment installation.
    • The use of sliding doors in aisle containment helps to maintain proper temperature and humidity levels, promoting optimal equipment performance and reducing the risk of overheating.
    • By segregating hot and cold aisles, sliding doors aid in efficient cooling and reduce the workload on HVAC systems, resulting in energy savings.
    • These doors can be integrated with environmental monitoring systems and automated controls to enhance the overall efficiency and effectiveness of the data center’s cooling infrastructure.
