BAC Updates Adiabatic Products, Expands Support for NASRC

Baltimore, Maryland (U.S.)-based Baltimore Aircoil Company (BAC), which manufactures evaporative heat transfer and thermal storage products, is expanding its line of TrilliumSeries Adiabatic products.

BAC’s adiabatic condensers/gas coolers are often used in supermarket installations of transcritical CO2refrigeration systems.The expanded TrilliumSeries line includes fluid cooler models for low-charge refrigeration applications, and software enhancements for all models to optimize fan energy and water savings, according to the company’s website.

Users can thus “reduce peak and annual energy use by 44% versus traditional air-cooled products or reduce water use by 90% versus traditional evaporative products” and “save on refrigerant charge with coil volumes reduced up to 90% compared to traditional equipment,” said BAC.

The software enhancements promise users better controlduring night-time operation and during the winter, BACsaid. “The day/night mode allows enhanced fan control for sound-sensitive applications” while the individual digital fan control “allows for winter fan shutoff on units serving multiple refrigeration racks.”

In addition, artificial intelligence for fan control allows for optimized system energy efficiency “even when no external fan signal is provided,” said BAC.

EcoFlex Controls will also maximize the adiabatic pre-cooling effect and fluid cooling during wet operation, and minimize water consumption, “reducing the total cost of ownership for the owner,” BAC said.

TrilliumSeries Adiabatic Fluid Cooler models “reduce refrigerant charge and footprint compared to typical condenser systems, which are particularly important on systems using hydrocarbon refrigerants,” added BAC.

The units are available across the full range of sizes with low hydraulic-pressure-drop configurations, to minimize system energy usage.

BAC Upgrades in NASRC

In addition to their new line of products and software, BAC has extended its support for the North American Sustainable Refrigeration Council (NASRC), a California (U.S.)-based nonprofit promoting natural refrigerant use in the grocery sector.
