3PL refrigerated distribution centers, grocery distribution warehouses, and cold-chain fulfillment buildings across Texas. Mixed cooler/freezer envelope distribution with ASRS and BMS integration.
A refrigerated warehouse is a different building from a blast freezer or a dedicated cold storage facility. The temperature mix is wider — a typical 3PL refrigerated distribution center has dock loading at ambient, a cooler envelope around 35°F for produce and dairy, a freezer envelope at -10°F to -20°F for frozen goods, and a dry-storage section at ambient. Each temperature zone has different electrical requirements: ampacity adjustments for cold-room conductors, vapor-tight luminaires sized for the zone, condensation-tolerant device boxes in transition spaces.
We deliver electrical scope for refrigerated warehouses across the spectrum: 3PL cold-chain distribution buildings, grocery distribution centers, e-commerce cold-chain fulfillment, and meat/produce processing facilities with attached refrigerated storage. The work spans new construction, retrofit of existing dry warehouses into refrigerated facilities, and capacity expansion within operating buildings.
Branch panelboards and distribution rated for each temperature zone. NEC 310.15(B) ampacity adjustments applied to conductors in cold rooms. Sealed device boxes and vapor-tight conduit fittings at zone transitions to prevent condensation migration.
Refrigeration plant MCC, VFD installations on screw compressor leads, evaporative condenser fan motor power, and evaporator unit power inside the refrigerated envelope. Plant sizing typically 500–3,000 tons for refrigerated warehouse applications.
Power distribution for refrigerated ASRS, conveyor systems extending into cold zones, and pick-to-light or voice-pick stations. VFDs on conveyor drives rated for cold ambient. MCC location decisions that balance accessibility with thermal exposure.
Refrigerated trailer plug-in receptacles at dock positions, typically 480V 3-phase 30A. Metering at each plug position for cold-chain billing. Dock leveler, restraint, and dock light power scope coordinated with refrigeration of the loading bay.
Vapor-tight LED luminaires rated for sub-freezing ambient operation, networked controls with occupancy sensing, and emergency lighting fixtures rated for cold-temperature start. Lux levels per IES warehouse and refrigerated storage recommendations.
Refrigeration plant controls (Logix, Danfoss AK-SM, CPC) tied to facility BMS. HVAC controls for ambient zones, dock door interlocks, and lighting control. Demand-response capability for facilities participating in utility incentive programs.
Texas is one of the largest US cold-chain markets, driven by Houston port volume, DFW national 3PL distribution position, San Antonio Mexico-border cold-chain traffic, and grocery distribution serving the Texas Triangle. New construction has been steady across the major metros, with operators including Lineage Logistics, Americold, United States Cold Storage, NewCold, and the grocery retailer captive distribution networks.
Most of our refrigerated warehouse work falls between 80,000 SF and 500,000 SF, with refrigeration loads from 500 tons to 5,000+ tons. We work outside that range when the project complexity or owner relationship justifies it.
Yes. Dry-to-refrigerated conversions require substantial electrical scope: refrigeration plant power, cold-room distribution, ampacity adjustments on conductors that move into cold zones, and frequently service-entrance upsizing to support the refrigeration load. We’ve done conversions where existing building bones are reused and where the electrical scope effectively rebuilds the distribution from the service entrance forward.
Yes. The refrigeration mechanical contractor designs and installs the refrigeration plant and refrigerant piping. Our electrical scope supports their plant: power to compressors, evaporative condensers, and refrigerant pumps; control wiring for refrigeration logic interfaces; and refrigerant detection wiring required for ammonia and CO2 systems. We coordinate scope splits and integration testing through preconstruction.
