Water-Efficient Adiabatic Heat Rejection with Low Charge Ammonia DX Refrigeration for Desert Cold Storage

• Water-efficient adiabatic heat rejection solution designed for desert climates.

• Energy-efficient DX performance with ADXi-enabled optimized superheat control.

• Reduced ammonia charge, increasing operational safety.

• Maximized freezer space and rooftop service access with evaporators located outside the storage area.

• Uniform airflow distribution through custom supply diffusers.

Grupo Bafar, a leader in food manufacturing in Mexico, expanded its operations in the U.S. with a new cold storage facility in El Paso,Texas. RSCS partnered with Colmac Coil to engineer a refrigeration system that minimized water use, reduced ammonia charge, maximized interior freezer space, and maintained high efficiency in a desert climate. The solution combined a water-efficient adiabatic condenser with a recirculated water design with A+Series® A+P Insulated Penthouse Air Coolers to enable a high-efficiency, low-charge ammonia DX system, while ADXi controls optimized performance and reliability. All refrigerant-bearing components were located outside human-occupied spaces and serviceable from the roof.
