CHW CRAC Cooling Systems

Chilled Water Precision Cooling for Data Centres & Industrial Facilities

Chilled Water CRAC systems (CHW CRAC) are commonly used in large commercial buildings, enterprise data centres and industrial facilities where central cooling plants already exist.

These systems use chilled water supplied from central chillers to regulate temperatures in server rooms and electrical infrastructure environments.

Facilities across Brisbane, Sydney and Melbourne often rely on chilled water precision cooling to support critical infrastructure.

What Is a CHW CRAC System?

A CHW CRAC system uses chilled water supplied from central plant chillers to cool air within server rooms and data centres.

Instead of using refrigerant compressors within the CRAC unit, the chilled water absorbs heat from the environment before returning to the cooling plant.

This approach is particularly effective in large facilities with existing chilled water infrastructure.

Advantages of CHW CRAC Systems

CHW systems provide several advantages in large environments.

Benefits include:

• very high cooling capacity
• efficient cooling for large buildings
• integration with existing chilled water plants
• stable temperature control for IT environments
• scalable infrastructure for expanding facilities

These systems are commonly used in enterprise infrastructure environments.

Disadvantages of CHW Systems

However, these systems also have limitations.

Potential drawbacks include:

• dependence on central cooling plant infrastructure
• higher installation complexity
• large mechanical plant requirements

CHW systems are generally not ideal for smaller server rooms.

Industrial & Mining Applications

Chilled water CRAC systems are frequently used in industrial and mining infrastructure.

Applications include:

• mining operations control centres
• industrial process control rooms
• large manufacturing plants
• telecommunications infrastructure hubs
• data processing facilities

These environments rely on stable cooling infrastructure to protect control systems and communications equipment.
