Data Center Cooling

Fluid Water Systems (FWS) and Technology Cooling Systems (TCS) keep data centers running by delivering precise coolant flow across heat exchangers, pumps, and distribution networks. High pressures, water-glycol and refrigerant chemistries, continuous cycling, and numerous connection points demand advanced sealing performance. Garlock provides engineered solutions that prevent leaks, protect uptime, and ensure reliable cooling under critical conditions.

Garlock MULTI-SWELL™ Style 3760 creates its own compressive load when exposed to water, maintaining a tight seal in low-load flanges where rubber or fiber gaskets may crush or weep over time.

MULTI-SWELL™ Style 3760 Pipe Flange Gaskets

Data centers rely on steel and HDPE liquid-cooling distribution loops to transport water-glycol or refrigerant-based coolants between chillers, coolant distribution units (CDUs), and heat-exchange equipment. Even small leaks can disrupt IT operations and facility uptime. Garlock MULTI-SWELL™ Style 3760 creates its own compressive load when exposed to water, maintaining a tight seal in low-load flanges where rubber or fiber gaskets may crush or weep over time. Recognized by the Plastic Pipe Institute for use with HDPE flanges, MULTI-SWELL™ helps ensure cooling system integrity.

Data Center Power Generation

For the critical power systems that sustain data center operations, Garlock provides sealing integrity you can trust. We leverage our industrial engineering heritage to deliver robust components capable of surviving the extreme heat, harsh chemicals, pressure, and vibration of power generation infrastructure. Our portfolio of heavy-duty gaskets and expansion joints effectively isolates exhaust and fuel systems from failure, ensuring that when the grid goes down, your facility remains operational. From diesel generators to gas turbines, Garlock safeguards the continuity of your power supply.

THERMa-PUR® Extreme Heat Pipe Flange Gaskets

Data centers depend on highly reliable on-site power generation and backup systems to maintain uptime during peak demand and grid disruptions. These systems operate under extreme heat, pressure, and thermal cycling, where conventional graphite materials can oxidize, stick, or degrade over time. Garlock THERMa-PUR is a hydrophobic, oxidation-resistant gasket material engineered for temperatures up to 1,000°C (1,832°F), maintaining seal integrity in high-temperature exhaust, turbine, and generator applications. With excellent torque retention and non-sticking performance, THERMa-PUR helps reduce leakage, maintenance time, and risk in critical data center power infrastructure.
