Cooling Efficiency Shouldn't Come at Water's Expense.

Cooling approaches that keep PUE low tend to drive WUE higher — consuming thousands of gallons of water per day to do it. As AI workloads push capacity to grow 2–3× by 2030, forward-thinking operators are demanding solutions that don't force a choice between energy performance and water responsibility.

Today's Reality

High Cost. High Waste. Heavy Chemistry.

💧
High water consumption
Conventional towers run at CoC 3–4, requiring constant fresh water makeup
Significant treatment costs
Chemical purchasing, logistics, dosing maintenance, disposal, and discharge consent charges
⚗️
Discharged water containing heavy chemicals
Requiring wastewater treatment prior to discharge
With OC Water

Lower Use. Lower Cost. Zero Chemicals.

💧
Up to 30% water savings
Running at CoC 6–8× instead of 3–4× reduces blowdown and fresh water draw
Save on chemicals, water & discharge
Eliminate chemical purchasing costs, reduce water abstraction bills, and cut sewer discharge charges from authorities
Zero chemicals discharged
Mineral concentrate only at blowdown — nothing synthetic leaves the site

A Smarter Approach to Cooling Water

Three integrated layers that replace traditional chemical treatment with clean, intelligent water management.

1

Clean Make-Up Water

We begin with high-purity make-up water to remove the contaminants that compromise cooling performance, asset life, and water efficiency.

2

Sustained Water Quality

Our proprietary hardware preserves water quality throughout the system, supporting reliable cooling operations while minimizing scale, corrosion, and biofouling.

3

Intelligent Operational Insights

Continuous monitoring and AI-enabled predictive insights optimize water use, surface issues before they escalate, and deliver automated reporting across the cooling environment.

Proprietary Hardware. Intelligent Software. One Integrated Platform.

Water treatment system
OC Water treatment system — reverse osmosis and disinfection hardware

Chemistry-free treatment

Replaces biocides, scale inhibitors, and corrosion chemicals with physical treatment processes — nothing synthetic enters or leaves the cooling loop.

High-recovery filtration

Closed Circuit Reverse Osmosis delivers high-purity make-up water while on-site generated Hydrogen Peroxide and in-line UV enable cycle of concentration ratios of >8 without chemistry.

Retrofit-ready & modular

Installs alongside existing cooling towers — no rip-and-replace — and scales modularly from a single building to a hyperscale campus.

Protect uptime

Early risk detection and sensor drift alerts surface issues before they become failures — keeping cooling stable and predictable.

Integrate with existing systems

Connects with site SCADA, BMS, and operational data — no rip-and-replace required.

AI-driven digital twin

A reinforcement-learning model that improves over time, adapting to your specific site conditions and optimizing continuously.

Calculate the water saving for your site.

Select your city and enter your heat load. The model uses a physics-based heat balance with actual temperature profiles for your location — not a generic percentage estimate.

How it works

The OC Water system runs your cooling tower at a higher concentration ratio — reducing blowdown and fresh water draw. Savings are based on a physics-driven heat balance using typical temperature profiles for your chosen city.
