Series AT represents decades of engineering excellence and is specifically designed for ease of access for maintenance, high durability, optimum efficiency and low power consumption. The AT is an induced draught unit available with special low noise fans and water noise absorbers for sensitive sites. The ULRA AT version combines all these features with AISI 316 stainless steel basin and AISI 304 stainless steel casing.Series LSTB is a traditional fan forced draught cooling tower, with inherently low noise centrifugal fans but can be fitted with additional attenuation if the application is hyper sensitive. This range of towers is ideally suited for indoor installation and applications which require extensive air inlet and outlet duct work.Series LPT is a variation on the LSTB and selected for applications which demand a low silhouette when placed behind a building parapet wall or screening. The LPT & LSTB product range is available in heavy galvanized (725 gm/m²) casing or AISI 304 or AISI 316 stainless Steel.
