Pecan orchards, dairy farms, vineyards and chile fields share the Mesilla Valley along NM 28, and every one of them produces something that has to be cooled before it ships. Around Hatch the chile crop is irrigated from wells and from ditches fed by the Rio Grande, Caballo Lake and Elephant Butte Reservoir, and the product leaves by truck on I-25. We build the cold storage that sits between the grower and the highway: coolers, freezers, blast chill rooms and refrigerated dock buildings, delivered as cold storage construction on a single contract.
A cold building is mostly insulation, vapor control and refrigeration, and it fails slowly when any of them is wrong. The common failures are frost heave under a freezer slab, wet insulation that loses its value, and ice at the dock door. We design against each one before the first footing is poured: underslab heat or ventilation under freezers, a continuous vapor barrier, insulated metal panels with sealed joints, and dock seals with vestibules at every door.
Heat makes cold storage an equipment-load problem in this desert. June highs average 96.2 degrees Fahrenheit, and a refrigerated dock that opens to that air several hundred times a day gives the compressors a heavy load. The building envelope, door cycle time and the way trucks are staged all affect the refrigeration bill, and we plan them together.
The structure starts below grade. A freezer slab needs insulation under the concrete and a way to keep the soil beneath it from freezing, either with heated glycol loops or with ventilated sleeves, and that decision comes before the foundation drawings. Above the slab, a panel system provides the thermal envelope, and the roof is detailed for water shedding and for the extra weight of refrigeration equipment.
The machine room, evaporators, racking and sprinkler system are specified alongside the building. Freezers often use dry or pre-action sprinklers so water is not standing in pipes that could freeze, and the machine room needs ventilation and leak detection. If you already own a building and want to add a cold dock, our refrigerated dock retrofits cut a new opening, add a vestibule and extend the refrigeration without taking the whole building out of service.
The dock is where a cold building loses most of its energy. We design vestibules, air curtains and insulated dock doors, and we place the dock on the side of the building that gets the least afternoon sun when the site allows. Truck staging is just as important. A trailer waiting with its refrigeration unit running at the dock produces noise, exhaust and a heat load that the layout should account for.
Spring afternoons in Las Cruces can be windy with blowing dust, so air intakes for condensers and machine rooms are protected and filtered. Arroyos around the area carry water after heavy thunderstorms, and a cold building with a low floor and a big impervious roof needs a drainage plan that moves water away from the dock apron. We grade the site and size the detention area for that burst, not for an average day.
NM 28 runs the length of the Mesilla Valley past farmland, dairy farms, vineyards and pecan orchards, and the communities on it, such as Chamberino, La Mesa and Vado, are close to I-10 through the connecting state roads. Hatch sits off I-25 and is served by the Southwestern Railroad. The result is a region where produce and nut handlers want storage near the field but with fast access to the interstate.
Processors are the other major buyer. Plants that clean, pack and portion product need cooler space inside or next to the plant, which we design together with the food and beverage processing plant. Distributors that hold product for days instead of hours look at distribution centers with cooler or freezer zones built into the warehouse.
The 2021 New Mexico Commercial Energy Conservation Code adopts the 2021 International Energy Conservation Code as amended and has applied to new permits since July 30, 2024. Refrigerated spaces have their own envelope requirements, and the panel insulation, air leakage and refrigeration equipment efficiency are reviewed in the energy compliance path. Electrical work follows the 2020 New Mexico Electrical Code.
Refrigeration systems that use ammonia above federal threshold quantities fall under process safety management rules, with documentation, training and inspection requirements that begin at design. We help owners decide early whether an ammonia, CO2 or halocarbon system fits the building, because that choice affects the machine room design, the permit path and the operating plan.
Cold storage rarely stands alone. Owners in the cold storage and refrigerated business and in food and beverage usually need truck courts, trailer plug-ins, an emergency generator pad and fire water as well. We bundle those into the same contract so the refrigeration load, electrical service and civil work are all designed for the same operating day.
We also build phased cold space: a shell sized for the final capacity, with refrigeration for the first phase and room reserved for the second. That keeps the first capital outlay low and avoids opening up the building later.
Give us the product, temperature range and pallet count, and we will outline a building, a refrigeration approach and a schedule. Call or use the form.
Yes, unless the soil is protected another way. Freezer temperatures can freeze the soil beneath the slab and push it upward, a condition called frost heave that cracks floors and racking foundations. Heated glycol loops or ventilated conduits keep the subgrade above freezing, and we size them for the freezer setpoint.
It makes it more expensive to run, and design can offset some of it. Reflective roofing, deeper insulation, sealed docks with vestibules and a well-placed condenser yard all reduce the load. The upfront cost is real, but the operating savings usually justify it.
It depends on size, staffing and local rules. Ammonia is efficient for large systems but triggers safety management rules above threshold quantities. CO2 and halocarbon systems are common for smaller or mid-sized rooms. We lay out the machine room and the permit path for each option so the decision is made with facts.
The refrigeration equipment and panels are the long-lead items, often several months. We order panels and compressors during permit review and schedule the slab and underslab work to be ready when they arrive. A mid-sized cooler can take much of a year from design to commissioning.
