Protect your plumbing process with this Thermaco Big Dipper W-250-AST 73 lb. automatic grease trap with advanced maintenance assistant! This helpful tool is often used in various commercial food service operations and works with cooking or prep sinks, pot sinks, and commercial dishwashers. By filtering wastewater from your attached sink or dishwasher, this machine isolates solids and grease, protecting your plumbing. The fully automatic self-cleaning cycle removes grease and oil from tanks without operator assistance, which reduces the time you spend cleaning the machine and prevents backup. Plus, with the advanced maintenance assistant feature, this model automatically empties and pushes small food particles downstream. This hygienic system reduces exposure to grease, food waste, and fats, by ensuring only 1 minute a day is spent emptying the grease collector.

For efficient operation, this grease trap is capable of skimming up to 9 lb. per hour. The skimming process makes removing and recycling grease quick and easy. With the integrated digital control and interface, you can easily control time and select a skim setting to meet the needs of your establishment. The compact footprint in combination with a 25 GPM flow rate and 73 lb. grease retention capacity make this unit ideal for any kitchen, and especially for under-sink installation. This unit also features Advanced Odor Protection to keep odors from escaping the tank, providing a more hygienic solution than other types of grease traps. It is constructed of corrosion-resistant materials to withstand frequent use, and boasts a durable and sanitary stainless steel exterior. This unit requires a 115V electrical connection.
