SPIRAC (USA) INC.

SPIRAC is a global engineering company headquartered in Alpharetta, Georgia, with over 40 years of experience designing and manufacturing shaftless spiral conveying and headworks equipment for municipal wastewater and industrial facilities. The company operates from offices spanning six continents and maintains a team of over 100 professionals. SPIRAC's core technology is shaftless spiral conveying — the SPIROLINE horizontal and inclined conveyor and the SPIROLIFT vertical conveyor handle sludge, screenings, and other difficult materials using spirals cold-formed from high-tensile micro-alloy steel (HTMAS) riding on SPX Duraflo liners. On the screening side, their lineup covers coarse through fine applications: the RAKEGUARD raked bar screen, MULTIGUARD multi-raked bar screen, BANDGUARD centre flow band screen, FINEGUARD moving fine screen, SPIROGUARD shaftless spiral screen, and DRUMGUARD drum screen, with the SPIROGUARD CSO handling combined sewer overflows. Screenings handling includes the SPIROPRESS dewaterer, SPIROPAC heavy-duty shaftless screw press, and SPIROWASH washer in both Compact/High Flow and Hi-Impact configurations. Grit processing is served by the SANDSEP classifier, SPIROSEP vortex separator, SANDWASH grit washer, and grit chambers. The COMBIGUARD packaged headworks system integrates screening, washing, compaction, and transport into a single unit. For biosolids, SPIRAC provides sliding frame silos, live bottom bunkers, truck receival systems, and SPIROTAINER containerized transport. Industrial markets include food waste, pulp and paper, slaughterhouse rendering, and winery operations.
