AHT Cooling USA has locations on four continents. It provides refrigeration solutions to major retailers everywhere. (Think large coolers holding food and drinks in your grocery stores and gas stations.) Cullum was hired by general contractor Charles Blanchard Construction Corp. to provide the air conditioning for the new 150,000 square foot manufacturing and warehouse facility located in Palmetto Commerce Park in Ladson. The original scope of work encompassed heating and air with seven rooftop units and an energy recovery ventilator (ERV) and associated duct work. Once on site, a change was issued to include a makeup air unit that supplies 100% outside air to the assembly line and a large propane exhaust system. Hard work and dedication pay off on this cool conquest.
