Choosing the Right Trapzilla
®
for You
Step One: Determine Flow Rate
Trapzilla Grease Interceptors are rated according to the ASME
A112.14.3 standard to separate grease efficiently at or below a specific
flow rate. This sizing methodology uses the principle that the highest
potential flow rates in a kitchen come from impounded water flows
when full sinks are emptied. In order to determine the maximum
potential flow for your kitchen, each sink compartment connected to
the grease interceptor must be sized using the formula below.
However, it is important to note that it is extremely unlikely that every
sink will be emptied at the same time in a restaurant. A WERF Study indicated that the average restaurant rarely sees
flows higher than 5gpm and never exceeded 25gpm. While it is valuable to protect against overflows, it is important to
understand that restaurants rarely reach 1/3 of peak flow.
Step Four: Choose Additional Options
Options are available depending upon the type of installation. Additional extension collars may be necessary depending upon
pipe depth. Be sure to determine depth from ground to center of pipe to make sure you have the correct options specified.
Step Three: Determine
Installation Conditions
Trapzilla offers a variety of models designed to
meet your specific installation conditions. See pages
6-7 for additional information on these models.

Step Two: Determine if Additional
Grease Capacity is Needed
Should extra capacity be necessary to meet local
code or to decrease pumping frequency, a larger
unit may be selected or additional Trapzilla units
may be added.
Trapzilla Grease Interceptors not only meet, but
exceed the grease capacity required by the ASME
A112.14.3 Standard for Hydromechanical Grease
Interceptors. The unique design of Trapzilla
maintains a flat separation curve within the unit
until it reaches 100% capacity, so it has the same
separation efficiency from day one until it is full.
If additional capacity is needed to meet local code, Trapzilla units should be installed in parallel when possible using a
Trapzilla Flow Splitter for equal distribution of flow and maximize the unique storage capacity of the units.
Note: Always use next larger size unit than the calculated flow rating.
To minimize grease/detergent emulsification, plumbing dishwashers directly into the
sanitary sewer line is recommended. Consult local codes or a licensed plumber when
considering plumbing a dishwasher to a Trapzilla unit.
Thermaco recommends the use of the TSS Trapzilla Solids Seperator (in conjunction
with a downstream Trapzilla Grease Interceptor) when used in facilities where heavy
loadings of incidental solids content in the effluent flow.
*The PDI-G 101 standard for calculating flow rate assumes a sink will not be
filled to more than 75% of its volume.
**One gallon of water is 231 in
3
. In dividing by 231, the unit of measure is
converted from cubic inches to gallons.
***The PDI-G 101 and ASME A112.14.3 standards, by which hydromechanical
interceptors are certified, use a 2 minute drain to determine flow rate.

Trapzilla® units are tested to the third-party ASME A112.14.3
Standard and outperform other grease interceptors of like
flow rating, storing as much as 9X more grease than the
test requires!
