Automatic
Grease and Oils Removal System removes free-
floating grease & oils from kitchen drain water
flows. As most food service facility managers
already know, grease buildup within a buildingʼs
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.
The 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 and/or eliminate pumping and
disposal costs associated with conventional grease traps or interceptors. The recovered grease
& oils are virtually water-free so local rendering companies or recyclers can collect it.
The Big Dipper system is an automatic, self-cleaning device. As greasy kitchen effluent drains
from kitchen fixtures, the unit traps the grease & oils. These separate from the effluent and rise
to the surface of the stainless steel tank. The unit automatically skims the trapped grease & oils
at least once per day and transfers the grease & oils to a collection container. A timer controls
the self cleaning operation, activating the skimming wheel at the proper time. Only the “cleaned”
water exits the unit and flows into the facility drain lines. The Big Dipper IS automatic systems
operate most efficiently when servicing single fixtures such as a 1 to 3-compartment sink or a
pre-rinse station.
The Big Dipper systemʼs stainless steel construction and compact footprint allows installation
directly at the source, where grease problems originate. The system design also allows easy
maintenance and operation by non-skilled personnel and requires only a minimal amount of daily
and weekly maintenance to maintain peak operating performance.
The Big Dipper system design allows for maximum installation flexibility. Reversing the system
operation is a simple as rotating the cover assembly of the unit.
