Gusmer Enterprises Cellu-Stack ® Housings

Gusmer Enterprises also offers a complete line of Cellu-Stack filter housings designed as a cost-effective system for high capacity liquid filtration applications. The versatile sanitary housing line accommodates either 12” or 16” diameter Cellu- Stack filter cartridges with the effective filtration surface area ranging from 17.7 ft 2 - 160.0 ft 2 . All housings are available in 1, 2, 3, or 4-cartridge versions, which can be modified with the use of Cellu-Stack adapters to accept fewer cartridges for partial batch runs or other applications requiring fewer cartridges. ASME code housings are also available if required. Cellu-Stack Application Notes: • Place a quick acting check valve at the housing outlet to avoid integrity breaches that can be caused by backpressure • Double check that all cartridge gaskets are in place and in good condition to ensure optimal sealing • If filter life is not fully exhausted by a single filtration, DO NOT remove used filters from the housing for storage between uses. Instead, used filters can be stored IN the housing by following these steps: - Shut Down: After completion of the filtration cycle, sanitize the filters with the same method used to prepare the filters (i.e. steam or hot water flush)
