Dallas Water-Cooled Chiller Plant & Cooling Tower Service | 24/7 Repair, Maintenance & Installs

How a Chiller Plant Works: Chilled & Condenser Water Loops

Chiller Types (Centrifugal, Screw, Scroll)

Your chiller is the heart of your cooling system. Centrifugal chillers work great for large buildings. Screw chillers handle variable loads well. Scroll chillers fit smaller applications. Each type has its place in Dallas commercial HVAC systems.

Condenser Water Loop & Cooling Towers (CTI Best Practices)

The condenser water loop carries heat from your chiller to the cooling towers. Here, fans and water evaporation reject that heat to the atmosphere. Proper cooling tower water treatment prevents scale and bacteria growth. Following CTI best practices ensures optimal performance.

Chilled Water Loop, Fan Coils & Air Handlers

Cold water from your chiller flows through the chilled water loop to fan coils and air handlers throughout your building. This loop needs the right flow rates and temperatures to keep spaces comfortable.

Pumps & VFDs (ABB, Danfoss, Yaskawa)

Pumps from Bell & Gossett, Armstrong, and Grundfos keep water moving. Variable Frequency Drives (VFDs) from ABB, Danfoss, and Yaskawa adjust pump speeds to save energy and match your cooling needs.

Heat Exchangers (Plate & Frame, Shell-and-Tube)

Heat exchangers transfer thermal energy between fluids. Plate and frame units offer easy maintenance. Shell-and-tube designs handle higher pressures. Both need regular cleaning for peak efficiency.

BAS & Controls (Johnson Controls, Siemens, Honeywell, Trane, Niagara N4 | BACnet/Modbus)

Building Automation Systems (BAS) from Johnson Controls, Siemens, Honeywell, Trane, and Niagara N4 monitor and control your entire system. Using BACnet and Modbus protocols, these systems optimize performance and alert you to problems.

Water-Cooled vs Air-Cooled for North Texas: Efficiency, Water Use, Footprint

Energy Efficiency & Lifecycle Cost in North Texas Climate

In Dallas's hot summers, water-cooled systems typically use 20-30% less energy than air-cooled units. Lower operating costs often offset higher initial investment within 3-5 years.

Water Use, Drift Control & Evaporation Considerations

Yes, water-cooled systems use water. But with proper drift eliminators and conductivity controllers managing blowdown, water waste stays minimal. Modern systems meet strict Dallas water conservation standards.

Noise, Footprint & Rooftop vs. Mechanical Room

Water-cooled chillers run quieter than air-cooled units. They fit in mechanical rooms, freeing up valuable roof space. This matters for Dallas high-rises and data centers.

When Air-Cooled May Be a Better Fit

Smaller loads under 150 tons or facilities with limited water access might benefit from air-cooled systems. We'll help you choose what's right for your specific needs.
