The type of grease interceptor needed will depend on the pipe diameter, maintenance requirements, waste water volume and available installation space. The larger the capacity of the trap the lower frequency of overall cleaning. The grease interceptor data sheets contain the information to help choose which best suit your needs. Be sure to note the diameter of the outlet pipe from the sink. The volumetric flow can also be determined by calculating the volume of water evacuation per minute. Just multiply the height x width x length in cm of the sink, the answer will correspond to the evacuation volume in cm3. Divide the result by 1000 to get the volume in liters. If you have 2 sinks connected to a single trap, you must add the total volume of both receptacles. The volume in liters divided into 1 minute provides the volumetric flow (L / min). The data sheet provides the recommendations for different volumetric flows. In reference to a house with a maximum of 5 residents, grease interceptor A is the best recommendation. For cafeterias and small restaurants we offer grease interceptor B. The larger sized grease interceptors are used mainly in food processing plants, condominium buildings and / or places where the diameter of the discharge tube is 3″ or 4”.
Once you have chosen the suitable drain, it’s important to specify the product code correctly. This is done as follows : Product Code – diameter pipe to feed – type of connection chosen – chosen material – desired finish – upper drain (if applicable) – type of grate (when applicable)
EXAMPLE 1
This information indicates the selection of the CI-145 drain for a 2” pipe, with embedded connection, aluminum lower plate and bronze upper drain with satin finish and C-121 (Grand Brilego) upper drain.
EXAMPLE 2
This information indicates the selection of the CI-141 drain for a 4” pipe, with embedded connection, aluminum body and grate, enameled finish with ¾ (75%) grate and ¼ (25%) open corner.
