Above-Ground / Floor Standing Grease Traps

Our range of above ground grease traps are available for internal and external installations. They are sometimes known as under sink grease traps, as they can be installed underneath or adjacent to the contaminating sink or other equipment within the kitchen area. For larger units, known as floor standing grease traps , can be centrally located within a plant room to take the complete wastewater drainage line from the entire kitchen.

Above ground grease traps can come as passive manual traps, hydro-mechanical or fully automatic self-cleaning systems. They can be easily accessed and serviced by either an engineer from Aqua Mundus, or for lower maintenance units, by a member of your establishment. We would always recommend a planned preventative maintenance  program on all grease management solutions to make sure your system remians remains compliant at all times.

Commercial under sink grease traps are the most common above ground grease traps that are installed due to the vast product range and the easy location access. This is echoed further within an existing kitchen or whether the system is designed for a new build establishment.

SSGT Stainless Steel Passive Manual Grease TrapsSSGT Stainless Steel Grease Trap

These robust units use a patented FreshMesh filter that is designed to filter out solid waste efficiently. FreshMesh filtration is proven to be effective with a high percentage of FOG (fats, oil and grease) capture. There is also the additional option of using the “super fine” FreshMesh system that removes coffee grounds from wastewater.

The system uses its internal baffle walls to prevent FOG from flowing out to the drain line. These units are installed with a 10-year warranty. They can be used in a single sink or a multi-sink kitchen and can manage dishwasher outflow. They are space efficient, requiring a minimum area to install and operate. Due to their versatility, SSGTs are easy to retro-fit and use standard plumbing fittings.

The SSGT is built to deliver years of service as it is constructed from 304 stainless steel. They also have a quick release watertight lid for simple inspection and cleaning. A stainless steel grease trap works by accepting the sink discharge water that contains food debris and FOG. Once inside the grease trap the FOG separates from the solid waste and floats to the surface. There is the option of biological dosing which can reduce the maintenance frequency and also help with odours during cleaning.

The remaining food waste is collected in the FreshMesh basket that then needs to be manually emptied into the general food waste bin.
