Liquid and Air Cooling Solutions for Data Centers
Historically speaking data centers have primarily used air cooling architectures. The advent of large language models has forced computational needs to exponentially increase. This densification raises the thermal load from chips and electronics, making liquid cooling a more reasonable choice versus air cooling. Keeping power quality in check is also critical to avoid damaging expensive electrical components utilizing the same local utility service.
VIDAR combines a high efficiency motor with embedded variable-speed intelligence and ultra-low harmonics performance up to 75HP, delivering a compact, efficient motor-drive solution for high-power data center cooling systems.
In Row CDUs and FDUs
In row coolant or facility distribution units sit away from server racks in either the "white space" or "grey space". Their purpose is to decouple the secondary chilled water loop from the tertiary one feeding server racks. These modular heat exchanging pump packages continue to demand more cooling capacity in a small form factor.
VIDAR provides OEMs the opportunity to save precious space with an integrated ultra-low harmonic motor package, available now up to 75HP.
Pair VIDAR with Johnson Pump's compact, sealed Combibloc family to accelerate engineering. One supplier can support hydraulic selection, motor sizing, and variable-speed integration.
Cooling Tower or Evaporative Condenser Fans
Cooling tower fans pull ambient air upwards over rows of water droplets. By doing so molecules with higher thermal energy evaporate while the cooler liquid falls into the basin. This cooler basin water heads to the chiller before returning back to the tower's spray nozzles.
As the enthalpy of outdoor air changes, so can VIDAR's speed to optimize approach temperatures and system efficiency. In addition, the IP55 motor, IP66 electronics, and coated surfaces prevent scaling or fouling of the internal components.
Dry Coolers/Condenser Fans/Air Cooled Heat Exchangers
Dry coolers, condenser fans, fin fans, and air cooled heat exchangers are names of the same type of equipment. A fan pulls ambient air over a heat exchanging coil carrying high energy refrigerant or process fluid, "soaking up" heat energy along the way.
VIDAR is best suited for fin fans and air cooled heat exchangers as they tend to be much larger than dry coolers and condenser fans. Operators may use digital inputs to program up to 15 set speeds akin to "stages" or use analog inputs to control speed to a process variable like temperature.
Condenser Water and Chilled Water Pumps
Condenser water pumps are responsible for transferring the condensed water sitting in a cooling tower's basin to a chiller. Inside the chiller this water flows into a heat exchanger where it absorbs some of the counterflowing refrigerant's heat energy.
Chilled water pumps simply take water or a water glycol mixture from the chiller's opposite heat exchanger and deliver it to end users such as evaporator coils in air handling units.
Using VIDAR here means less complexity for operators, project engineers, electrical engineers, and others. What would be several components placed around the facility is now all on one baseplate (pump, motor and VFD). In addition, VIDAR can alarm for dry running events.
