Data Center Cooling
Efficient Pump Solutions for High-Density Data Centers
As data centers move toward higher rack densities, liquid cooling is becoming essential for reliable performance, lower energy use, and long-term equipment uptime.
Tark Thermal Solutions provides advanced pump technologies for coolant distribution units (CDUs), economizer systems, rear-door heat exchangers, and immersion cooling. Our solutions support 50-200 kW Data Center Racks, with scalable options for even larger systems.
Our Solutions and Applications
Cooling Applications We Support
Coolant Distribution Units
CDUs regulate and distribute coolant between facility water loops and IT equipment cooling loops. Pump performance directly affects coolant flow, pressure stability, and temperature control across the rack or row.
Tark Thermal Solutions offers high-efficiency pump solutions for direct-to-chip CDUs, supporting consistent flow, compact integration and reliable operation in water-based cooling systems.
Rear-Door Heat Exchangers
Rear-door heat exchangers remove heat from server exhaust air before it returns to the room. These systems require reliable coolant circulation to maintain stable heat transfer and reduce the load on room-level cooling infrastructure.
Our pump solutions support compact, high-density designs where space, flow control and long service life are important.
Economizer Cooling Systems
Economizer systems use favorable outdoor conditions to reduce mechanical cooling demand. Pumps help circulate coolant through air-side or water-side economizer loops, enabling free cooling when environmental conditions allow.
Efficient pump selection can reduce energy consumption and improve overall cooling system performance.
Immersion Cooling
Immersion cooling submerges electronics in dielectric fluid to transfer heat directly from high-power components. These systems require controlled fluid movement to maintain thermal uniformity and protect sensitive electronics.
Tark Thermal Solutions supports immersion cooling systems with compact, efficient pump technologies designed for continuous operation in demanding thermal environments.
Our Pump Technologies for Data Centers
Centrifugal pumps
Centrifugal pumps are designed to move high volumes of coolant in low-to-medium pressure applications. They are well suited for CDUs, economizer systems, and other cooling loops where stable, continuous flow is required.
Key benefits include energy efficiency, flexible integration, and cost-effective operation across a range of liquid cooling architectures.
Wet-Rotor Pumps
Wet-rotor pumps combine the pump and motor in a compact, sealed design. The coolant surrounds the rotor, helping reduce mechanical complexity, operating noise, and maintenance requirements.
These pumps are ideal for compact CDUs and liquid cooling systems where quiet operation, reliability, and efficient integration are important.
Regenerative Turbine Pumps
Regenerative turbine pumps are used when higher pressure is required at lower flow rates. They are suitable for dense cooling loops, long fluid paths, and applications that require precise pressure control.
Tark Thermal Solutions RT Series regenerative turbine pumps support demanding cooling systems with operating pressure capabilities up to 600 PSI and construction designed for high-pressure reliability.
Brushless DC Pumps
Brushless DC pumps provide efficient motor operation, precise speed control, and long service life. Variable speed control helps match coolant flow to system demand, improving energy use and thermal response.
The LogiCool™ TCDU Series supports water-based direct-to-chip cooling with flow rates from 10–60 GPM / 38–225 LPM and pressure capabilities up to 33 PSI / 2.25 bar.
