Environ Engineering Company Offers Energy Efficient Aerator. It Has A Fabricated & Machined Base Frame For 5hp To 15hp Rating & For 20hp & Above Upto 50hp Heavy Ismb Beam Base Is Used. So Vibrations Are Lessened & Again The Base Is Machined On The Top Surface, So The Life Of The Gearbox Is Increased. The Cantilevered Load Reaction Is Passed Through Additional Bearings And Housing To Beam Base Bottom To Rcc Platform. So Gearbox Is Not At All Affected By Overhung Load. So Life Of The Gearbox Is Increased. The Floor / Base Support Area Is 100 Times More, So Possibility Of Vibrations Is Reduced Accordingly. Due To Conical Impeller And Solid Ms Shaft, Cg Lies Nearer To Center, So Less Impact Loading. The Impeller Is Machined At Centre For Its Concentric Running. Since The Shaft Is Fully Machined, No Possibility Of Voubling Of Shaft Concentric Running Of Impeller Is Ensured. Since Horizontal Foot Mounted Motor Is Used, The Conditions Are Not Seviour As Those Of Flange Mounted Motor. Maintenance Of The Gearbox Is Minimal & Handling Is Easier, As The Extra Bearings Are Provided To The Impeller Shaft. Spares Of The Worm Gearbox Are Easily Available At Comparative Lower Cost. Wetted Parts Are Frp Lined. Oxygen Transfer Test As Per International American Standard & Wrinklers Procedure Of All The Proto Type Aerators Upto 150hp Are Taken In Their Inhouse Oxygen Transfer Testing Facility Before Placing In The Market & Specially Designed Impeller Is Offered For Higher Water Depth Upto 6.0 Mtrs. Aeration Tanks. (Less Area For Aeration Tank Is Required, So Saving In Space).
