The Big Dipper®


The Thermaco, Inc. Big Dipper® Automatic Grease and Oils Removal System removes up to 98% of free-floating (non-emulsified) grease & oils from kitchen drain water flows. Grease build-up within a building's plumbing drainage system is a major cause of problems due to drain line blockages. These problems jeopardize normal operations as well as create health and safety hazards within the facility itself. Proper installation of a Big Dipper® System can reduce or eliminate grease problems. Use of the Big Dipper® assures minimization and/or elimination of costly sewer surcharges and fines through efficient separation and removal of free-floating grease & oils. In addition, the Big Dipper® also helps reduce or eliminate pumping and disposal costs associated with conventional grease traps or interceptors. The recovered grease & oils are substantially water-free and are suitable for recycling by local rendering and/or biodiesel companies.
