As data centers adopt high-performance liquid cooling, water quality control has become critical. Many cooling systems now use Trichlorine (TCCA) dosing to maintain clean, bacteria-free water in the cooling loop.
To meet the chemical, mechanical, and installation demands of these systems, Stilonn Valves & Controls Pvt. Ltd. has engineered a specialized range of PN 16 Tri-Clamp End Butterfly Valves designed for Trichlorine Signature Applications in data centers.
These valves combine sanitary connection flexibility with industrial-grade pressure performance, making them ideal for next-generation cooling infrastructure.
Why Tri-Clamp Ends Are Preferred in Data Center Cooling
Tri-Clamp (TC) sanitary connections are increasingly favored in data center environments because they provide:
- Fast installation without threading or welding
- Leak-tight sealing suitable for treated water
- Superior corrosion resistance
- Smooth internal flow path reducing pressure loss
- Easy maintenance and replacement
Additionally, tri-clamp systems allow clean routing of pipes inside chilled water skids, CDUs, and rack-level cooling modules.
Trichlorine (TCCA) in Cooling Water — Why Special Valves Are Needed
Trichlorine-treated water helps:
- Control bacteria, algae, and biofilm
- Maintain coolant hygiene
- Protect heat exchangers and pipework
- Improve system uptime
However, TCCA introduces chemical stress on valve components. This requires careful selection of:
- Body materials
- Disc materials
- Seat elastomers (EPDM/Viton/PTFE)
- Shaft and sealing design
Stilonn designs each valve according to the chemical concentration and operating conditions of the customer’s application.
