Cooling, Water and Mechanical Yards for Horizon City, Texas Data Centers

Heat leaves a data center through its mechanical yard, so the yard is where a desert site wins or loses. At 4,026 feet of elevation, Horizon City receives just 9.00 inches of precipitation in a year, which is desert country where water is scarce and the air is thin. We build mission-critical shells and the cooling plants, pipe racks, tanks and equipment pads that serve them, and we choose the cooling method with the water supply in view from the first sketch.

Air cooled chillers need little or no water but draw more power and need more land. Systems that reject heat through evaporation use less power but need a reliable supply and a plan for treatment and discharge. Neither choice is correct everywhere. We price both against the parcel, the utility rates and the water available, and we show the owner what each costs to build and to run.

The sections below explain the site factors, the schedule, the permits, who uses the space, the area, the scope and our method for turnover.

At 4,026 feet, air has less density, and fans and air cooled coils move less heat than their sea level ratings suggest. We ask manufacturers for performance at the site altitude, and we size the yard for the derated figure. Summer peaks are the design condition, and the plant must still hold temperature on the hottest afternoon.

Dust is the other desert factor. Wind carries fine particles that foul coils and filters, so we specify coil coatings, filtration and washdown access, and we lay out the yard so that maintenance crews can reach each unit. Our chiller and cooling plant pads work includes foundations, isolation and the pipe supports.

Mechanical yards sit on the critical path because chillers, pumps and piping have long lead times. We release orders early, pour pads while the shell goes up and place equipment as soon as the pads have cured. Pipe pressure tests and flushing follow, and then controls are loaded and checked.

Construction must also fit the heat. Concrete placed in summer needs early morning pours, shading and curing measures, and we plan the calendar around those limits.

Delivery coordination covers more than trucks. Utility shutdowns for tie-ins, water connections and inspection visits all need dates, and we put them on one calendar that the owner and every trade partner can read. When a date moves, the calendar shows what moves with it.

A cooling plant that uses water brings questions about supply, backflow protection, treatment chemicals and discharge. We ask the water provider about capacity and metering and ask the local authority about discharge limits, then reflect the answers in the design. The building department reviews the construction permit, and we submit the mechanical, electrical and structural sets together when the design is complete.

Land use also needs checking. Under a 1994 state law, the Colonia Act, parcels smaller than 10 acres cannot be sold for homes, which holds back small lot development to the east. It does not govern a commercial data center directly, but it shows why we confirm lot size, ownership history and zoning before a buyer commits to a parcel.

A 40,000 square foot Hospitals of Providence campus, developed jointly with the micro hospital firm Emerus, includes an emergency room, an inpatient wing, laboratory work and diagnostic imaging. Such a facility depends on imaging archives and clinical systems, and it is a model of the enterprise tenant who wants computing space nearby.

The city also names Wal-Mart as its retail center, with new shops and eateries opening along the main thoroughfare. Retail operations need payment networks and inventory systems that cannot fail. We build edge data centers for these needs.

FM 1281 is the road that carries the name Horizon Boulevard, and the old town grew up near its crossing with Kenazo Street. Trucks follow that road toward Interstate 10, and we plan crane and truck access for it. We also coordinate with El Paso suppliers, and we compare long haul routes with those for projects in Odessa and Midland.

A site near the original town core has existing streets and utilities, while land farther out may need road work and extended lines. We price that difference up front, because the cost of bringing power, water and fiber to a remote pad can exceed the cost of the pad.

Our scope covers site grading, the shell, the equipment pads, chilled water or condenser water piping, pump rooms, tanks if the design needs them, and the electrical feeds for each unit. We also install containment for any fluids, drainage for washdown and screens that control noise toward neighbors.

The cooling water supply and reuse lines package is the part owners ask about most. It includes the connection to the supply, the metering, the treatment skid and the lines that return or reuse water where the design permits.

A central utility plant is the building type that carries the cooling story, but it serves data halls, colocation suites and enterprise rooms alike. We design the plant with space for added chillers, so the owner can add capacity as the load grows without shutting the facility. Pipe stubs, valved connections and spare pump bays are placed during the first phase, and the structural design allows for the later equipment.

The enterprise and financial institution page describes the redundancy levels that such owners usually choose for their cooling.

We treat commissioning as the end of the construction schedule, not a separate event. Each piece of equipment is started, tested and documented in sequence, and the pieces are then tested together under load. Cooling is proved with load banks that make heat, and the controls are watched as conditions change.

At turnover the owner receives test records, drawings that match the field, operating manuals and trained staff. Our integrated systems commissioning scope sets the levels of testing in writing before the first start.

Share the megawatts of heat to be rejected, the parcel and the water options you have. We will compare cooling methods and give you a yard layout and a commissioning plan.

Is air cooling or water cooling better in Horizon City?

It depends on power cost, water supply and land. Air cooled systems save water but use more power and space. We compare both for your parcel and load and show the build and operating costs.

Does the altitude change equipment selection?

Yes. At about 4,026 feet, air is thinner, so fans and coils move less heat. We obtain derated ratings from manufacturers and size the yard to them.

How is cooling tested before turnover?

We run each unit, then the full plant, against a load bank that creates heat equal to the design load. Temperatures, flows and alarms are recorded and reviewed with the owner.

What do you need to start a water supply discussion?

The peak and average demand, the cooling method and the parcel location. With those, the water provider can say whether capacity exists and what the connection will cost.
