SIDE CHANNEL BLOWERS - Seko

1 side CHANNEL BLOWERS innovation > technology > futureSide CHANNEL BLOWERS2water and industry > side CHANNEL blowersOperating principleThe side CHANNEL blower or exhauster increases the pressure of the aspirated gas by the creation, in the peripheral toroidal CHANNEL , of a series of vortex caused by the centrifugal thrust of the the impeller is rotating, the vanes force the gas forward and, because of the centrifugal thrust, outwards, producing a helical motion. During this motion, the gas is recompressed repeatedly with a conseguent linear pressure increase along the length of the and advantagesThe side CHANNEL blower are suitable for all those applications requiring considerably higher pressuers than that which can be achieved using centrifugal fans. side CHANNEL exhausters are used in all those applications requiring an operating vacuum higher than the achievable by a fan, but not as high as to require the use of a vacuum rotating parts are not in contact with the casing.

2 There is thereforeno friction during operation and thus no internal lubrification is necessary. The gas moving through the machine therefore remains uncontaminated and completely oil-free. The other main advantages of using side CHANNEL machines are: easy installation low noise level non vibration and therefore complete dynamic stability pulsation free discharge minimal maintenanceAccessoriesA complete range of accessories is available for all machines:cartridge type filters for BLOWERS / in-line filters for exhausters / flexible hoses / non return valves / pressure relief valves for BLOWERS / vacuum relief valve s for exhausters / pressure and vacuum gauges / acoustic principle Casing and impellers are made of aluminium alloy. The standard machines for air are manufacturated in the so-called CLOSE COUPLED versione; a flange mounted electric motor is bolted to the machine casing. The impeller, which is dynamically balanced, is fitted directly onto the motor shaft extension.

3 The two-pole electric motors, designed for continuous operation, are available in three phase for allthe powers shownin the catalogue and in single phase up to 2,2 kW. They are manufactured according to IEC Specifications with the following standard features: - for machines with BLxxx010/020 suffix degree of protection: - IP55 insulation class: - F for powers up to 3 kW - H for powers 4 kW and above line voltage:- three phase motors, at 50 Hz 230 V / 400 V for powers up to 3 kW 400 V / 690 V for powers 4 kW- three phase motors, at 60 Hz 265 V / 460 V for powers up to 3,6 kW 460 V / 795 V for powers 4,8 kW- single phase motors, at 50 Hz 230 VFor 50 Hz supply, the allowed voltage variation is 10% according to IEC 38 60 Hz supply, as well as for motors specifically requested, for any other voltage at 50 Hz or at 60 Hz, a 5% tolerance on supply voltage is allowed, in accordance with IEC 34 Specification.

For the handling of gases other than air, steam, indistrial gases and mixture of explosive gases, special gas tight units can be manufactured. In case of corrosive gases, all the internal parts can be treated or lined with protecting coatings.~240~275 side CHANNEL BLOWERS3innovation > technology > futureBLOWERS ingle StageSingle ChannelSingle ImpellerBLOWERD ouble StageDouble ChannelDouble ImpellerBLOWERD ouble StageDouble ChannelSingle ImpellerFlow rates refer to air at the suction conditions of 20 C and 1013 mbar available upon requestTOLERANCE ON FLOW RATE VALUES: 10%[ ] BL040 THREE PHASES MOTOR: 0,9 KW - SINGLE PHASE MOTOR: 0,8 KW[ ] BL420 THREE PHASES MOTOR: 1,6 KW - SINGLE PHASE MOTOR.

10 There has been increased interest in fine pore diffusion of air as a competitive system due to its high Oxygen Transfer Efficiency (OTE). Smaller bubbles result in more bubble surface area per unit volume and greater aeration systems can be classified into three categories:- Porous (Fine Bubble) Diffusers: Concept of the fine bubble corresponds to the size of 1- 3 mm. These diffusers come in various shapes and sizes, such as discs, tubes, domes, and Nonporous (Coarse Bubble) Diffusers: These are in the form of perforated piping, spargers etc. The bubble size of these diffusers is larger than the porous diffusers (larger than 10 mm), thus lowering the Other Diffusion Devices: Jet aerators, aspirators, and U of the Diffused Aeration SytemThe performance of diffused aeration systems under normal operating conditions is directly related to the following parameters:- Wastewater characteristics,- Process type and flow regime,- Loading conditions,- Basin geometry,- Diffuser type, size, shape, density, and airflow rate,- Mixed liquor dissolved oxygen control and air supply flexibility,- Mechanical integrity of the system,- Operator expertise,- Fouling,- The quality of the preventive operation and maintenance per diffuser [Nm /h]45670 Oxygen Transfer Efficiency [%]102030406 diffusers/m 1 diffuser/m 505 m4 m3 m6 mSeko sends the equipments which are bought by you and thus usage period of the products will be started.
