Rofett grease traps/separators are designed for underground fitment and installation into commercial premises producing wastewater containing fats, oils and grease. The Rofett require low maintenance and deliver long lasting performance making them an ideal choice to prevent damage to sewer pipes and wastewater treatment facilities.
Manufactured in accordance with EN 1825 Roto, grease separators are made from environmentally friendly material (polyethylene LLDPE). They are very durable, lightweight and resistant against various chemical substances used in kitchen.
Rofett Size Range
Eight models are available ranging from 500 ltr to 12,000 ltr: NG2, NG3, NG4, NG6, NG10, NG15, NG20 & NG25. All models have a large sealed lid allowing easy access for cleaning.
What size of grease trap do I need?
The size of grease trap is determined by number of meals or the maximum possible flow of contaminated water, type of pollution, effluent temperature and detergent use. You can calculate by the formula: NG = Qs * fd * ft * fr * fm
Underground grease separators should be located close to the building in areas where release of strong and aggressive odours will not pose a problem and where it is possible to access the separator with the disposal hose of the disposal truck. The inlet level must be located below the frost level. The grease separator has to be opened for emptying and cleaning and should be easily accessible for cleaning and maintenance.
Manufactured in polyethylene, which is 100% recyclable and ribbed for reinforcement. Roto supply the Rofett rotomoulded tanks in one piece with a large opening for ease of cleaning. The tanks have a 400mm to 600mm diameter plastic cover, depending on size, with a seal making them watertight. The Roto tank wall thickness ranges from 8-14mm to give the tank its stiffness.
