A. The oxygen transfer values given above is obtained in
standard conditions defined as
pure water, in absence of oxygen
at 20 C with atmospheric pressure
in optimum tank geometry and mixing conditions.
Due to the many facts that influence this test kindly refer to our
office for proper sizing of aerator
and tank for single applications.
B. Within the operation range of workin~ suggested for each power I oxygen transfer efficiency Kg °iKWH remain constant.
Power absorbed and hen~ total O transfer can be varied usually with OL special type of baseplate.
C. Rotor is made of carbon steel sheet I it is sand blasted to
SA 2.5 then coated by epoxy laver of 200 micron thickness.
Rotor: Rotor is in fiberglass of monolithic construction, corrosion resistant internally reinforced with a steel structure and completely filed with closed cell polyurethane foam. Rotor is floating and this neutralizes downwards-dynamic thrust. In this way a longer life is assured for gearbox bearings, Corrosion in any type of effluent also visually not exist ant and no maintenance over the years is required. The inclination of the blades (integral part of the rotor) and rotor-curved profile optimize the pumping rate as well as oxygen transfer.
Motor: First class make, LP 55 protected motor for continuous outdoor operation is fitted. It can be suited to any local electric feed characteristics (voltage, cps) and for any type of environments.
Dual polarity as continuons variable speed motors is available on option.
Gearbox: First class make, precision built gearboxes to suit any particular requirement of the customer are available. Special care is being taken on the service factor, bearing life, materials etc. to ensure a trouble free, and long lasting life to cope with rotor characteristics.
Oxygen transfer efficiency: giants. It constituted galleggiantir The oxygen transfer values given in the data sheet is obtained, 6 standard conditions defined as pure water, in absence of oxygen, at 200 C with atmospheric pressure in optimum tank geometry and mixing conditions. Due to the many facts that in fluency this test kindly refer to our office for proper sizing of aerator and tank for single applications.
Power absorbed variation: Within the operation range of working, suggested for each power, oxygen transfer efficiency Kg 02/ KWH remains constant. Power absorbed and hence'total02 transfer can be varied Wally with our special type of base plate and/or with telescoping gearbox, option
Low speed aerator on pontoon: available for varying level applications. It features amply oversized and adjustable floats (in fiberglass on option) and of all steelwork. orrosion resistant surface finish is standard (hot dip galvanized in option). Special water level COM pensation devices are available to keeps the aerator in operation, tensioned with water level changing.
