The Cooling Challenge in Data Centers

Data centers are the backbone of the digital economy, housing servers that demand uninterrupted uptime and stable thermal control. Cooling systems—chillers, condensers, heat exchangers, and immersion cooling units—operate around the clock, often under extreme loads.

The biggest risks? Fouling, corrosion, and scaling in cooling equipment. These issues reduce efficiency, raise energy costs, and increase the likelihood of unplanned outages. With Data Centers Coatings from Curran International, operators can protect critical infrastructure, reduce maintenance cycles, and optimize cooling performance.

Curran International’s Solutions for Data Centers

Thin-Film Anti-Foul Coatings
Curran’s ultra-thin, hydrophobic coatings (typically under 25 microns) reduce surface energy, making it harder for deposits, particulates, or biofilm to stick to heat transfer surfaces. This ensures heat exchangers, chillers, and immersion cooling equipment remain efficient longer—helping stabilize power usage effectiveness (PUE).

High-Performance Epoxies & Fluoropolymers
Curran applies durable epoxy systems (Curran 1000/1200/1500) and fluoropolymer coatings (PFA, PTFE, ETFE) for components exposed to harsh cleaning, water treatment chemicals, or aggressive fluids. These coatings maintain long-term corrosion resistance without compromising hygiene or efficiency.

Tube Liners for Critical Equipment
In cases where condenser or chiller tubes show corrosion, Curran installs hydraulically expanded, full-length alloy liners in situ. This restores performance without the cost and downtime of full retubing—ideal for mission-critical data center cooling assets.

Comprehensive Surface Preparation
Using dry grit blasting, Curran achieves NACE 1 “white metal” cleanliness before coating. This ensures maximum adhesion and long-lasting coating performance—even in aged equipment.

Benefits of Data Centers Coatings

  • Improved Cooling Efficiency
    Coated surfaces resist fouling and scaling, maintaining heat transfer efficiency and reducing compressor or pump loads.
  • Reduced Energy Consumption
    Cleaner exchangers mean lower PUE and trimmed operational costs—a critical KPI for modern data centers.
  • Extended Asset Life
    Corrosion protection adds years of reliability to condensers, chillers, and cooling loops.
  • Lower Maintenance Costs
    Less fouling means fewer cleanings, less downtime, and more predictable O&M budgets.
  • Operational Resilience
    Reliable cooling ensures servers remain within optimal temperature ranges, preventing outages or throttling.

Typical Applications in Data Centers

  • Immersion Cooling Systems – Thin-film coatings prevent fouling in liquid cooling loops.
  • Chiller & Condenser Exchangers – Coated for long-term performance against scaling and corrosion.
  • Plate-and-Frame Heat Exchangers – Enhanced release surfaces reduce cleaning cycles.
  • Cooling Towers & Water Boxes – Epoxy and fluoropolymer coatings extend service life in high-moisture environments.
