Trapping grease and making it easy to stay in compliance

Traditional grease traps are a hassle to maintain. They must be emptied regularly, or else grease builds up to the extent that they no longer work properly. That can lead to on-premises sewage back-ups and excessive fats, oil and grease getting into the sewer system.

And if too much grease gets into the sewer system, sooner or later that can cause blockages and lead to costly, embarrassing fines for your food service establishment.

But traditional grease traps can be difficult to maintain. And in some circumstances, they can be difficult or costly to install.

Thermaco's innovative Big Dipper solves those problems. It has a compact footprint, operates automatically and is easy for your kitchen staff to empty — no pumper truck needed.

The Big Dipper series includes units that can handle single sources of grease, such as a three-compartment sink, or plumbed to handle all the grease produced in a kitchen. There are also systems to handle food solids separation.

Simple Installation

Big Dipper units can be installed on your kitchen floor, often underneath or next to the three-compartment sink. It's compact footprint and easy installation makes it fast and easy to implement; any licensed plumber can do it.

Easy Operation

Wastewater from the sink or other wastewater source flows through the unit automatically. Periodically, triggered either by a timer or a sensor, a skimmer wheel activates and pulls grease from the top of the wastewater and deposits it into a separate waste compartment.

Staff members do not have to open the unit to determine how thick the grease mat is or whether it needs to be emptied.

The isolated grease in the collector is simply emptied into a municipally approved waste container or disposed with other kitchen trash.

Compliance plus plumbing protection

Not only does the Big Dipper keep your kitchen compliant with sewer regulations, it also protects your plumbing. Because most of the fats, oil and grease are intercepted by the Big Dipper, they don't even flow through your internal wastewater lines. That helps protect those pipes from grease build-up, which can lead to blockages in your internal plumbing and costly repairs.

Some facilities with long wastewater lines will use a Big Dipper along with an exterior grease trap to minimize the wear and tear on their own plumbing.

Food particle interception

In addition to intercepting grease, Thermaco also offers products for separating small food particles (such as rice and coleslaw) from kitchen wastewater. These include in-line and flat strainer baskets, which are emptied by hand, and the Automatic Solids Transfer series of Big Dipper, which flushes incidental solids down the sewer line with the clean effluent.
