Ensure sparkling, streak-free glassware and superior hygiene standards with the Smeg SPG405MAU Ecoline Professional Undercounter Glasswasher. Designed and manufactured in Italy by Smeg Professional, this premium compact glasswasher is purpose-built to meet the rigorous washing demands of bars, cafés, restaurants, bistros, and hotels. Note: The SPG405MAU is the official direct replacement for the popular legacy model UG405DMAUS.
Built with heavy-duty AISI 304 stainless steel and a double-skinned insulated door, the SPG405MAU accommodates 400mm x 400mm racks (plus an adapter for 17" x 14" baskets) with a generous 330mm door clearance. Equipped with Smeg’s advanced HTR (High Temperature Rinse) system—incorporating an atmospheric boiler and dedicated rinse booster pump—it guarantees a constant 85°C rinse temperature at uniform pressure, using just 2.3 litres of water per cycle. Featuring a soft-start wash pump to protect delicate stemware, electronic controls with 3 fast wash programs (starting at 90 seconds), integrated peristaltic chemical dosing pumps, and a 3-stage dynamic filtration drain system, it delivers rapid, spotless sanitisation.
