A grease seprator is essential wherever grease-containing waste water is produced during the cleaning or processing of food.
It protects wastewater systems from blockages, prevents unpleasant odors and meets legal requirements in accordance with DIN 4040-100. Our grease separators offer you a reliable, maintenance-friendly solution – individually plannable, robust in design and ideal for long-term use in kitchens, businesses and food processing facilities.
With our combination of over 45 years of experience and innovative technologies, we offer you efficient, reliable and environmentally friendly separator systems for light liquids.
We help you find the right system for your requirements
– quickly and professionally.
A grease separator is always required when fatty wastewater is discharged into the public sewer system – for example, in commercial kitchens, restaurants, butcher shops, bakeries, canteens or food processing plants.
The legal basis for this is DIN 4040-100 in conjunction with the respective municipal drainage regulations.
The aim is to separate fats and oils from wastewater at source in order to prevent blockages, unpleasant odours and damage to the sewer system.
A grease separator reliably separates grease, oil and solids from wastewater before it is discharged into the public sewer system.
The cleaning process begins in the inlet filter:
Here, solids are mechanically separated from the wastewater by a screen and automatically transported to a collection tank by a screw conveyor.
The remaining fatty wastewater flows into the separation area, where separation takes place by means of gravity – fats and oils, being lighter components, rise to the surface.
To ensure that these remain fluid for disposal, the grease collection chamber is thermally insulated and equipped with an integrated heating system.
A grease drain tap allows liquid fats to be discharged fully automatically and without additional energy consumption into a separate collection tank. The purified wastewater leaves the system via a drain connection and can be fed directly into the public sewer system.
The grease separator system consists of a robust, rectangular stainless steel container (V4A, material 1.4571) with a conical grease collection chamber and meets the requirements of DIN EN 1825-1. The separate disposal of grease and sludge and the program-controlled fully automatic operation make the system particularly efficient, hygienic and low-maintenance. The separated residues can also be recycled in an environmentally friendly and resource-saving manner.
Do you have questions about design, equipment or regulations?
We provide personalised, solution-oriented advice.
Our grease separator system combines intelligent functions with robust construction. Every component is designed for durability, efficiency and ease of use – for reliable operation and maximum safety in everyday use.
Inlet filter can be connected as an option
The grease separator can be supplemented with an upstream inlet filter to effectively separate solids in advance.
Water- and odour-proof container lid
The lid is equipped with a seal and quick-release fasteners and ensures a secure, odour-proof closure of the system.
Grease layer thickness sight glass (Ø 100 mm)
A large sight glass allows easy visual inspection of the grease layer thickness in the collection area.
Temperature-controlled heating underneath the fat layer
An integrated heater with temperature sensor keeps the fat layer liquid, ensuring safe disposal.
Electrically controlled grease disposal
Disposal is fully automatic via an electrically driven butterfly valve connected to the collection container.
Collecting tank provided on site
The grease separator is prepared for connection to the collecting tank provided by the customer.
Filling level monitoring of the collection containers
Both grease and solids containers are monitored by sensors to provide timely warning of emptying.
Odour-free ventilation (DN 100)
The system has a central ventilation connection that enables effective and odor-free discharge of the process air.
Sampling device at the outlet
A sampling point is integrated at the outlet so that water samples can be taken for quality assurance purposes.
Control cabinet with plain text display and fully automatic operation
A compact control cabinet (approx. 500 × 500 mm) controls all processes, enables manual operation and displays faults in plain text.
Do you have questions about the function, maintenance or legal requirements of grease separators? You will find the most important answers in our FAQs – clearly laid out, easy to understand and practical.
What is a grease separator and what is it used for?
A grease separator separates fats, oils and solids from wastewater, preventing them from entering the sewer system – important, for example, in restaurants, food production or commercial kitchens.
Where is the use of a grease separator required by law?
Wherever fatty wastewater is produced – e.g. in restaurants, hotels, canteens, butchers, bakeries or food processing plants – local authorities require the use of a grease separator in accordance with DIN EN 1825.
How does a grease separator work?
It uses the principle of gravity: fats and oils, which are lighter than water, rise to the surface; solids sink to the bottom – the purified wastewater is then discharged into the sewer.
How often does a grease separator need to be emptied?
Emptying must be carried out regularly – daily, weekly or at least monthly, depending on usage. The exact intervals are regulated by municipal regulations or the operating log.
Who is authorised to perform maintenance and emptying?
Disposal is usually carried out by certified specialist companies or, with the appropriate expertise, can also be carried out by the customer themselves.
How do I find the right size for my grease separator?
The nominal size is calculated based on the amount of wastewater, type of use and local requirements – we are happy to assist you with the design in accordance with DIN EN 1825-2.
