Computer Room Air Conditioning (CRAC)

Precision Cooling for High-Availability IT Facilities

At Layer 1 Technologies, we design and implement advanced precision cooling systems (CRAC) for data centers and IT rooms where reliability and efficiency are critical. Our solutions ensure constant temperature and humidity control, optimized airflow, and high energy efficiency. With top-tier equipment and smart controls, we deliver stable environmental conditions, low PUE, and reliable 24/7 operation.

Computer Room Air Conditioning (CRAC)

CRAC precision cooling unit for high-availability data center environments

Technical Scope

  • Thermal study and design of cooling architecture based on IT load density and room layout.
  • Selection and supply of CRAC, in-row, and in-room cooling systems according to operational and energy requirements.
  • Installation and full commissioning of cooling units, including air distribution and flow balancing.
  • Integration with DCIM or BMS systems for continuous environmental monitoring and alarm management.
  • Implementation of hot aisle / cold aisle containment systems to enhance airflow efficiency.
  • Deployment of precision components such as inverter compressors, EC fans, and free cooling systems.
  • Preventive maintenance and technical support with SLA options and spare parts availability.

Frequently Asked Questions - FAQ

What makes a CRAC system different from a conventional air conditioner?

CRAC systems are purpose-built for data centers and IT environments, offering precise, continuous control of temperature and humidity — not just general space cooling. They maintain stable environmental conditions and protect sensitive IT equipment from overheating.

They are designed to:

  • Operate 24/7 with high reliability and redundancy (N+1, 2N).
  • Deliver directed airflow to IT equipment (underfloor or in-row) rather than general room cooling.
  • Integrate with DCIM/BMS systems for real-time performance monitoring and automated control.

Our Approach

At Layer 1 Technologies, we view cooling as a core element of data center reliability. Each design begins with an in-depth analysis of thermal load, energy consumption, and operational goals. Our team provides a complete solution — from air distribution and containment to energy optimization — achieving superior PUE performance.
We work closely with clients to ensure that each CRAC system is fully aligned with their technical and operational requirements, from initial study to commissioning and support.

Ensure stable operation and maximum uptime with a precision CRAC cooling system designed for your facility’s needs.
