RoGra — compact grease separator for underground installation.
EN 1825-2 certified. Capacities from 1 to 4 L/s.
The RoGra is an HDPE grease separator for underground installation, EN 1825-2 certified. Its compact geometry suits sites with restrictions on excavation depth or width. Available from 1 to 4 L/s — ideal for restaurants, cafés, small community facilities and small-scale catering units.
Why the RoGra?
Where the kitchen or the outdoor area is tight on space, the RoGra offers a compact footprint without compromising the grease retention capacity required by law. With the grease chamber and settling chamber integrated into the same shell, it delivers legal compliance with a single unit and a single trench.
Rotationally moulded in HDPE, the RoGra does not corrode and stays watertight over the years. The DN600 cover with telescopic extension allows the access level to be matched to the paving finish, whether in a garden area, a car park or a pavement. Fast installation — direct pipe fitting, with no mandatory concrete surround.
