Improve cooling efficiency

CRB Water programs help data centers maintain uptime, improve cooling efficiency, and reduce resource waste by stabilizing water quality and preventing costly surprises.

Cooling Risk

Scale, corrosion, and biofilm in cooling towers reduce heat-transfer efficiency, increase water and energy use, damage critical equipment, and raise the risk of cooling disruption and downtime.

System Degradation

Corrosion caused by poor water chemistry can lead to pitting, leaks, shorter equipment life, and more frequent maintenance.

Resource Waste

Inefficient cycles of concentration and excessive blowdown increase makeup-water demand and operating costs, especially in water-stressed regions where every gallon counts.

Frequently Asked Questions

What parameters do your data center water monitoring and automation systems track?

Depending on the system configuration, CRB Water can monitor parameters such as conductivity, pH, ORP, chemical feed and inventory levels. Automated controls, alerts and trend reporting help identify changing conditions and support timely treatment adjustments.

How does water treatment impact data center cooling performance?

Water treatment directly affects heat transfer efficiency, system reliability, and energy use. Poor water quality can lead to scale, corrosion, and biofilm that reduce cooling performance and increase operational risk.

How much water does a data center use?

Water use varies widely based on facility size, climate, cooling technology and operating load. Facilities using evaporative cooling generally consume more onsite water than air-cooled or closed-loop alternatives. Optimizing cycles of concentration and blowdown can reduce unnecessary cooling-water use.

What types of data center cooling systems do you treat, and how do their water requirements differ?

CRB Water supports evaporative cooling towers, closed-loop chilled-water systems and applicable water systems associated with liquid cooling. Treatment requirements vary based on source-water quality, system materials, operating temperatures and equipment-manufacturer specifications.

What is WUE in data centers?

Water Use Effectiveness (WUE) measures how much water a data center uses relative to its IT energy consumption. Lower WUE values indicate more efficient water usage and improved sustainability performance.

How does an optimized water treatment program help improve data center WUE and PUE metrics?

Optimized cooling-water treatment can support WUE by allowing appropriate cycles of concentration and reducing unnecessary blowdown. Controlling scale, corrosion and biofilm also helps maintain heat-transfer efficiency, which can support energy performance. The effect on WUE and PUE depends on cooling design, climate and operating conditions. See the results in our data center water efficiency case study.

How is cooling tower water treated in data centers?

Cooling-tower programs typically combine scale and corrosion control, biological treatment, monitoring and automated chemical feed. The specific program depends on makeup-water quality, operating conditions and facility sustainability goals.

How quickly can CRB Water respond to urgent issues?

CRB Water prioritizes urgent system conditions through local field support, technical troubleshooting and dependable product delivery.

What’s involved in switching from our current vendor?

Our step-by-step changeover plan maps chemical inventories, transitions dosing safely, and stocks local supplies. That helps minimize downtime and disruption, while creating a smoother path to better results.

Do you provide reporting for sustainability and compliance audits?

Yes. CRB Water’s monitoring and reporting tools document water use, chemical feed, and discharge performance, giving you clear records to support compliance reviews and internal sustainability reporting.

Can your programs integrate with our existing monitoring systems?

In many cases, yes. We align with your current automation, controls, and reporting platforms, layering in data-driven treatment and lab audits to strengthen what you already have in place.
