Modern data centers demand highly efficient and reliable cooling strategies. AI workloads and high‑density compute racks drive unprecedented thermal output. Hartell delivers purpose‑engineered pumps for data center cooling systems, and specialty condensate pumps for data center thermal management. It supports the unique environmental, reliability, and uptime requirements of today’s digital infrastructure, for long term pump solutions.

 

Data center cooling pumps remove condensate from cooling coils in CRAC and CRAH units. These data center cooling pumps protect servers, GPUs, and storage from moisture and overflow risk.

Hartell designs condensate pumps for demanding plenum spaces and high temperature environments.

Hartell pumps offer adiabatic, evaporation, and hybrid systems in both standard and AI data centers.

Which Hartell Pumps Serve Data Center Cooling Systems?

Below are key Hartell pump families used in CRAC, air handlers, and data center coolers.

 

KL‑1DG Low Profile Condensate Pump

  • Compact, low profile design for tight plenum spaces in CRAC units.
  • Max head: 5.5 m (18 ft) for reliable condensate lift. 
  • Reservoir: 1.0 L (0.26 gal) for steady flow control. 
  • Flow rate: 208 L/h (55 gal/h) for continuous duty operation. 
  • Available in 115 V, 230 V, and 277 V versions. 
  • Plenum‑rated to 100 °C (212 °F), UL 2043 and UL 60335 compliant. 

A3X High Temperature Condensate Pump

  • For larger CRAC units and air evaporation cooling cabinets. 
  • Max head: 7.3 m (24 ft) supports flexible routing to drains.
  • Reservoir: 3.8 L (1.0 gal) suits higher condensate volumes.
  • Flow rate: 1 330 L/h (351 gal/h) for high capacity systems. 
  • Voltage options: 115 V, 230 V, 277 V. 
  • Plenum‑rated and approved for high temperature environments. 

A5X High Head Condensate Pump

  • For long runs or high vertical lifts in dense white spaces.
  • Max head: 14.6 m (48 ft) for flexible plant layouts. 
  • Reservoir: 3.8 L (1.0 gal) delivers stable pump cycles. 
  • Flow rate: 2 080 L/h (550 gal/h) for large CRAC banks. 
  • Voltage options: 115 V, 230 V, 277 V. 
  • Plenum‑rated to 100 °C (212 °F) for hot aisles and ducts. 

How Do Hartell Pumps Support Data Center Cooling Design?

Technical designers face higher rack power densities and strict uptime targets. AI racks can reach 40 kW per rack, more than double standard racks.

Hartell condensate pumps help by:

  • Managing higher condensate loads from efficient coils and adiabatic systems. 
  • Supporting plenum installation to simplify drainage routes and cabinet design. 
  • Withstanding high air temperatures up to 100 °C (212 °F). 
  • Helping protect PUE and WUE through reliable condensate removal. 

As liquid and immersion cooling grow, condensate still forms in many hybrid systems.
Hartell monitors these shifts and adapts pump technology for future architectures.
