Digester equpiment Gas treatment Gas storage Gas flare Gravel filter GRF The gravel filter enables the coarse filtration of the biogas by passing through a gravel layer. Foreign particles, foam and condensate are removed and channelled to a drainage point. The filter can be easily accessed through a screwed cover for cleaning. Contamination can be easily removed without the need for opening the cover by rinsing with water. The gravel filter is available for various volume flow rates and pressures. As an option we provide accessories i.e., gravel removal flange or differential pressure gauge. Highlights Options • Simple, maintenance free design • Gravel removal opening through screwed flange • Low pressure loss • Equipped with pressure gauges • Easy access through screwed cover for differential pressure indication • Automatic removal from condensate water • Rinse system with ball valve and spray nozzle • Inlet and outlet connections for pressure gauges • Manufactured entirely from 1.4571 stainless steel • Made in Austria Gravel filter GRF technical data Model Height Connections in Nm ³/h in mm in mm DN 80 480 1,460 50 GRF 150 150 480 1,460 65 GRF 250 250 480 1,460 80 GRF 80 Flowrate Diameter GRF 350 350 640 1,460 100 GRF 500 500 800 1,460 125 GRF 750 750 955 1,500 150 GRF 1000 1,000 1,270 1,500 200 GRF 1400 1,400 1,270 1,600 250 ennox biogas technology GmbH Neulandstr. 36, A-6971 – Hard, Austria T: + 43 55 74 / 66 4 88 F: + 43 55 74 / 66 4 88 - 100 www.ennox.at welcome@ennox.at Version 26.04.12 E
