Characteristics and Construction

Rosenberg Radial Fans with free-running impeller type E/DKHR form a compact and constructively optimal fan unit by combining an external rotor motor and a backward-curved impeller.

During development of the backward curved impeller, Rosenberg attached great importance to high efficiency and at the same time a most optimal sound level.

Fans of this construction are designed for installation in appliances such as air handling units, hygienic units, clean room filter units and air conditioning units.

The fans are for clean air application and ventilation of non-aggressive vapors and fumes.

The standard execution is the construction:

• _KHR : Motorized impeller without inlet cone (inlet cone as an option)

Available on request:

• _KHM : Fan module

• Special solutions according to customer requirements (OEM)

E/DKHME/DKHR

Page 6: Backward Curved Motorized ImpellersH-series: The impellers with 6 backward curved blades are made of polyamid 6.6 with 30% fiber glass. The back plate of the impeller is galvanized

H-series:

The impellers with 6 backward curved blades are made of polyamid 6.6 with 30% fiber glass. The back plate of the impeller is galvanized steel. Aluminum impellers are available as an option.

W-series:The impellers with 8 backward curved blades are made of Aluminum sheet (AlMg3). Steel impellers with epoxy coating can also be supplied if requested.

The impellers are statically and dynamically balanced with external rotor motor according to quality level G2,5 DIN ISO 1940

The direction of rotation of the impeller viewed from the inlet side is clockwise. Wrong direction of rotation can overload the motor. It is essential to check the direction of rotation prior to operation

The inlet cones are made of galvanized steel They are fluidic optimized to supply a good airflow towards the impeller. The optimal immersion depth of the impeller is described .

Rosenberg external rotor motors are in protection class IP54.

The winding insulation corresponds to insulation Class F. Ball bearings, closed on both sides are used. Special grease lubrication provides maintenance-free operation, low-noise and extended life.

All motors are equipped with thermal contacts, wired in series. Thermal contacts are temperature dependent control elements, sensing the winding temperature of the motor These contacts protect the motor windings from overload, failure of a mains phase, locking of the motor and from too high temperatures of the medium to be ventilated.

In addition to the mounted thermal contacts we recommend the use of our motor protection control units.

Rosenberg also offers 5-step voltage controls, RTE and RTD types.By use of this controllers an additional motor protection switch is not required.

The nominal voltage given on the nameplate provides maximum allowable voltage tolerance of ± 10%.

Flying leads are standard.The connection ends are 10 cm (4 inches) dismantled and equipped with end splices. Standard cable length is 68 cm (27 inches) Special cable lengths are available on request.

For single phase operation, motors are available for 115V, 208/230V and 277V.All 230V motors could also be used at 1~230V, 50Hz.

For three phase operation, motors are available for 208V / 230V∆ // 460V Y.

575V and other special voltages are available on request.

Please reference 60Hz-curves:

- Standard three phase motor can be used at 460V (Star connection) and 230V (Delta connection). In Delta connection the motors are also suitable for 208V 3~ power supplies).- The performance curves show that the 230V∆ performance is a little less than the

460VY performance.The standard three phase motors could also be used at 400V Y, 50Hz.

Speed control can be provided for fans that demand optimal adjustment of the operation point. Speed control is obtained by “Voltage Control” and “Frequency Control”, as described below.

The speed control is provided by reduction of the terminal voltage. If the voltage will be reduced the speed of the motor decreases and the air volume flow sinks in proportion with the speed. The matching voltage controllers can be provided on request.

All voltage controllable fans for three-phase power supplies can also be speed controlled by frequency converter from 60Hz downwards. The speed control is realized by reduction of the power supply frequency. At higher frequencies than 60Hz the motor will be thermally overloaded.

With operation of the motors on a frequency controller the maximum speed of voltage increase of 500V /µs must not be exceeded. According to the frequency converter type and the length of the cable between motor and frequency converter additional components must be planned. Please refer to the operation manual of the frequency converter.

A simple volume flow determination and monitoring in an installed condition is possible with ring testing wire on the inlet cone. For this the manufacturer places the relevant gauging performance curves at one's disposal

The fans are constructed for installation within customer provided casing. We do not include guards of any kind as a part of our standard product offering. Please contact your Rosenberg representative for accessory information. Before initial operation all required protection components must be installed and connected. Adherence to all electrical and safety codes, including National Electric Codes (NEC), National Fire Protection Association (NFPA) standards and Occupational Safety and Health Act (OSHA) should be followed and are responsibility of the customer. All electrical connections should be performed only by qualified personnel.

Rosenberg radial fans with free running impeller are usable machines according to the EC Council Directive on Machinery. They are marked with a CE label and delivered with a declaration of conformity.

The dangers of the fan as well as necessary technical measures of safety are judged according to the VDMA standard sheet number 24167: Fans, demands of safety.The operation manual contains additional measures of safety to be realized on site to make the fan match the EC Council Directive on Machinery 98/37/EC.

Air Performance Curves

The air performance curves have been established using the inlet test method in the test chamber as shown below according to German standard DIN 24163. They are valid for air with a density with a temperature of 68°F. The performance curves were made in mounting position A (free inlet, free outlet) and show the pressure increase, available on inlet side, pfa as a function of the volume

of 0.075#/ft³

Installation in casings or air handling units

We recommend to use the installation ratio

Internal dimension of casing A>1.6

external dimension of impeller D

when installing a radial fan with free-running impeller into a casing. The following diagram shows installation losses with recommended and too small installation ratio.

1 Catalogue performance curve without casing: 100% nominal air performance

2 Performance curve with A/D = 1.6: 98% nominal air performance

3 Performance curve with A/D = 1.2: 92% nominal air performance

On the inlet side a minimum distance of 0.5 x D to adjoining parts has to be kept. So losses on pressure side must not be taken in consideration.

The expected sound pressure level on the outlet side can only be approximately determined as the ambient influences can lead to strong deviations.
