UNO-ME

Unobox-ME Exhaust fans for higher operating temperatures

·    Motor outside the air stream
·    high air stream temperatures possible
·    with integrated emergency switch
·    Motor protection by thermal contacts
·    integreated drip pan
·    condensate drain in scope of delivery (supplied loose)

_____________________________________________________________________________________________________

Description:

The Rosenberg Unoboxes-ME are designed to handle air volumes with higher temperatures. Typical applications are to exhaust kitchens, production shops and other areas where polluted air has to be exhausted.

Note for use in kitchen exhaust:
The  Unobox-ME  is  suitable  for  use  in kitchen exhaust according to VDI 2052.  A removable door maintanance, an integreated  drip  pan  with  condensate  drain  connection  and  the  special  sealing  lips  are also part of the delivery standard such as the outside of the air stream arranged engine.
In the kitchen exhaust must be used a insulating connection (Type: DS).

Application areas:
Garage / Bars / Skyscrapers / Hotels / Industrial buildings / Playschool / Parking facilities / Nursing homes / Schools / Sports halls /  Supermarkets /  Workshops / Residential houses / Fitness centers / Inflatables / Kitchens / Bakeries

Reference to Directives:
 Declaration of incorporation and operating instruction are according to Machinery Directive 2006/42/EC, CE identification in accordance to EMC-Directive 2014/30/EU, Low Voltage Directive 2014/35/EU and the Ecodesign-Directive 2009/125/EC.

Casing:

The  housing  supporting  frames are double chamber aluminum profiles with corners made of plastic and double skinned (20mm) galvanized steel panels insulated with non-inflammable, noise and temperature insulating fibreglass mats. Outlet and side panel can be changed. The base plat is designed as an integreated drip tray.

_____________________________________________________________________________________________________

Impellers:

The  impellers  together  with  the  hubs are balanced dynamically at two levels according to quality levels G2.5 to DIN 1940.


The fans are equipped with high efficiency backward curved centrifugal impellers made of aluminum.
The complete motor-impeller assembly can be removed.

_____________________________________________________________________________________________________

Motor and motor protection:

All Rosenberg fans are  equipped with  direct driven  external rotor motors.  All our fans have motor protection  through thermal contacts in the motor windings as standard. The motors apply to protection class IP44/IP54.


The drive has due to an external rotor motor a space saving, compact and attractive design. The motor is fitted within the impeller, which enables the best possible cooling. For this reason  a  100%  variable speed control can be guaranteed. V-belts, additional tension bars and motor mounting devices are  not necessary.  Only well-dimensions ball-bearings,  fitted on both sides and  life  time  greased are  used.
Both ball-bearing seats are  ground to high  precision in one work process to eliminate  any  vibrations.
External rotor motors have extremely low starting currents.  The windings  comply to  isolation class F.
In addition the windings have a standard moisture impregnation.

Electrical connection:

Standard variant:
By default pre-mounted on the front side of the housing repair switch. The supply of power is thus made ​​to the isolator.

Installation:

Direction of rotation:
Direction of rotation is clockwise, viewed from the inlet side.

WARNING: Counter-clockwise operation will cause overload damage to the motor!

Important notes:

Air performance curves:

The performance curves for these fan types have been measured in mounting position A (free inlet; free outlet) and indicate the pressure increase ∆pfa as a function of the air flow.

Noise levels:
The  bordered  values printed in the performance curve diagrams show the "A"  weighted  LWA6  sound power level (fan outlet. Determination of "A" weighted LWA5 sound power level at fan inlet:

LWA5 [dB(A)] = LWA6 [dB(A)] - 4 dB

The "A" weighted sond pressure level LpA at a distance of 1 metre is calculated approximately by deducting 7 dB(A) from the "A" weighted sound power level. It is important to note that the reflection and room characteristic as well as natural  frequencies influence the sound pressure levels a different way. The relative octave sound power level LWArel at octave medium frequency you can find on the table on each fan type page.

Classification of the fan series:
NRVU    = Non Residential Ventilation Units
UVU    = Unidirectional Ventilation Units

Erp-Information:
Rosenberg fans have a spezfic (pressure-) ratio < 1,05 (pressure < 5000 Pa).

Service life:
For maximum service life of Rosenberg products please beware of the maintenance hints on the manual for each product type.

Recycling and disposal:
For recycling and disposal of Rosenberg products comply with applicable locally requirements and regulations.

Unoboxes-ME Exhaust fans for higher operating temperatures

The  housing  supporting  frames  are double chamber aluminium profiles with corners made of plastic and double skinned (20mm) galvanized steel panels insulated with non-inflammable,  noise and temperature insulating fiberglass mats. One side of the casing is open as standard. The integrated drip tray in the bottom plate of the Unobox-ME also use in the kitchen exhaust area is possible, the drainage plug is supplied loose. The accumulated fat in the exhaust air is passed through special sealing lips of the inside of the housing into the tub and can be discharged via the condensate drain.

The impellers together with the hubs are balanced dynamically at two levels according to quality levels G2.5 to DIN 1940. The fans are equipped with high efficiency backward curved centrifugal impellers made of aluminium. The complete motor-impeller assembly can be removed.

The motor is out of the air stream. For this reason a 100% variable speed control can be guaranteed. Only well-dimensions ball-bearings, fitted on both sides and life time greased are used. Both ball-bearing seats are ground to high precision in one work process to eliminate any vibrations. External rotor motors have extremely low starting current. The windings comply to isolation class F. In addition the windings have a standard moisture impregnation.
