Frequently Asked Questions
What is the Vertiv Liebert PCW?
The Liebert PCW is a perimeter chilled-water precision cooling system for data centers, with capacities from about 11 to 220 kW per unit. It uses chilled water from a central plant, an optimized coil, and EC fans to deliver high efficiency and capacity per footprint while holding tight temperature and humidity tolerances.
When should I choose chilled-water over DX cooling?
Chilled-water cooling like the PCW is typically more efficient and scalable at larger capacities and is the right choice when you have or plan a central chilled-water plant. DX cooling suits smaller spaces without a chilled-water loop. Comp-Utility evaluates your size, growth, and existing infrastructure to recommend the right approach.
What is the benefit of high entering-water temperature?
Designing for higher entering-water temperatures lets the chilled-water plant use economization (free cooling) for more hours of the year, reducing mechanical cooling energy and improving PUE. The PCW supports this capability. Comp-Utility designs the system and setpoints to capture economization benefits where the climate allows.
How do I size chilled-water cooling for my data center?
Sizing is based on the IT heat load in kW, redundancy target, and growth, coordinated with the chilled-water plant capacity and flow. Comp-Utility calculates the heat load, recommends unit count and capacity for N+1 or greater redundancy, and designs the piping and airflow to deliver cooling where it is needed.
Can the PCW be deployed redundantly?
Yes. PCW units are deployed in N+1 or greater configurations so the space stays within tolerance during a unit failure or maintenance. Comp-Utility designs the cooling redundancy to match your tier and uptime goals and coordinates it with the chilled-water plant and power redundancy.
Is chilled-water cooling a good fit for Central Texas?
Yes. For larger Central Texas data centers, chilled-water systems like the PCW offer efficient, scalable cooling, and high entering-water-temperature designs can capture economization hours. Comp-Utility sizes the system for local peak conditions and designs for efficiency across the year.
Who installs and services the Liebert PCW in Central Texas?
Comp-Utility, a long-standing Vertiv distribution partner, specs, installs, commissions, and maintains the Liebert PCW across Central Texas, including preventative maintenance and 24/7 emergency response. Call (512) 346-0999 or email sales@comp-utility.com.
What maintenance does chilled-water cooling require?
Maintenance includes filter changes, coil cleaning, valve and actuator checks, EC fan inspection, condensate management, water quality and flow verification, and controls and setpoint checks. Coordinated chiller-plant maintenance is also important. Comp-Utility provides scheduled service to keep the system efficient and reliable.
