Computer Room Air Conditioning Systems (CRAC Units) – Precision Control for Data Center Environments

Professional cooling solutions specifically designed for server rooms and data centers, ensuring stable temperature and humidity control and protecting digital infrastructure around the clock.

Systems are considered CRAC Units (Computer Room Air Conditioning) the standard solution for cooling server rooms and data centers, fundamentally different from conventional air conditioning systems in terms of precision control, high reliability, and continuous response to fluctuating thermal loads.

Who is this service for?

CRAC solutions are specifically developed for:

Server Rooms

server room inside a hospital or government facility

Data Centers

Telecommunications and Network Rooms

Banks and Financial Institutions

Hospitals and Government Entities

UPS Room

These systems are designed to simultaneously control:

Temperature with high precision

To maintain a stable temperature within the recommended range for server rooms without fluctuations that could affect equipment performance.

Humidity Level

Controlling humidity within safe limits to prevent condensation or static electricity that could damage servers.

Uniform Air Distribution Within the Room

Directing cold air evenly to server inlets to ensure uniform cooling and prevent the formation of hot spots.

In alignment with the operational requirements of servers and sensitive network systems, following best practices adopted by leading global companies such as Trane, Carrier, and SKM.

How do CRAC unit systems operate inside server rooms?

The CRAC Unit (Computer Room Air Conditioning) is a precision cooling system specifically designed to handle high and continuous thermal loads generated by servers and networking equipment, while maintaining a stable operating environment without sudden fluctuations.

It operates on the principle of continuous and precise cooling, rather than the intermittent operation commonly used in conventional air conditioning systems.

Operating Mechanism (Simplified Engineering Approach)

Hot Air Return

Hot air discharged from the servers is drawn through dedicated return inlets, typically from the upper or rear sections of the server room.

Air Treatment Inside the CRAC Unit

Lowering the air temperature, controlling humidity levels, and filtering the air from fine particles

Cold Air Redistribution

Cold air is recirculated in a controlled and uniform manner through raised floors or dedicated distribution ducts.

Continuous Control and Immediate Response

CRAC systems rely on precise sensors that continuously monitor temperature and humidity around the clock, automatically adjusting performance as needed.

Why is this system different?

According to the standards of leading global companies such as Trane and Carrier, CRAC systems are characterized by:

Higher control precision than commercial air conditioning systems
Capability to operate 24/7 without interruption
تصميم مخصص للتعامل مع Heat Density العالية
Protection of sensitive equipment from condensation or excessive dryness

United’s Methodology in Designing and Implementing Computer Room Air Conditioning (CRAC Units)

At United HVAC, CRAC systems are not treated as standalone units, but as integrated engineering solutions that begin with load analysis and conclude with fully documented, commission-ready handover.
We follow a clear execution methodology tailored to server room and data center projects, where precision, reliability, and operational continuity are critical factors.

Engineering Analysis of Thermal Loads

Assessment of heat density generated by servers and equipment.
Analysis of load distribution within the room (Static / Dynamic Load).
Consideration of future expansions and redundancy requirements.

Cooling System and Air Distribution Design

Selection of the appropriate system type (CRAC / CRAH / integration with a raised floor).
Designing airflow paths to prevent hot spots.
Setting temperature and humidity control setpoints in accordance with operational standards.

Equipment Selection and Technical Specifications

Selection of approved CRAC units based on the project capacity.
Defining the control type, efficiency level, and continuous operation requirements.
Aligning specifications with the consultant’s and owner’s requirements.

Engineering Execution and Installation

Execution strictly in accordance with approved drawings, without temporary solutions.
Precise adjustment of air paths and connections.
Full coordination with electrical systems and monitoring systems.

Testing, Commissioning, and Handover

Testing & Commissioning تحت الأحمال التشغيلية.
Adjusting temperature and humidity control settings.
Providing clear technical and operational reports to the owner.

Why is this methodology important for the client?

Facilitating solution approval by the consultant or technical management
Reducing long-term operational risks
Ensuring the stability of the critical server room environment

Why do clients trust us in implementing CRAC unit systems?

We don’t sell just a unit, but a fully integrated AC system built for long-term efficiency

Experience in Critical Environments

Implementation of CRAC systems for facilities operating 24/7, with a clear understanding of continuity requirements and zero-tolerance for downtime.

Commitment to Standards and Regulatory Requirements

Application of the Saudi Building Code, regulatory authority requirements, and approved data center standards.

Clear Execution Methodology

Design, implementation, and testing of systems according to approved procedures that ensure performance compliance prior to handover.

Focus on Operational Stability

Engineered solutions that ensure consistent performance, ease of operation and maintenance, even as loads vary over time.
