What is a Goslyn™? The Goslyn™ Grease Recovery Device is an immiscible liquid separator designed for food processing & preparation, and other applications that generate Fats, Oils, Grease & Solids (FOGS). The patented operating technology of Goslyn™ separators virtually eliminate FOGS in waste water effluent. There are no moving parts to break and no messy, time-consuming grease traps to clean. Plus…it's small footprint makes it easy to install in even the smallest prep kitchens. Seeing the remarkable Goslyn™ Separator in action will provide you with a true sense of its compact “install anywhere” footprint, ingenious design and highly efficient operation.
