air circulation systems can achieve up to 70 per cent energy savings .
The internal bearings within WEG ’ s W22 Smoke Extraction motors correspond with the C4 code . Selecting the appropriate C code for bearings is crucial for both the bearing and the machine ’ s performance — the code encompasses all pertinent bearing characteristics including material , lubrication and internal bearing clearance . C4 means the W22 Smoke Extraction motors ’ internal bearings can maintain these characteristics for up to two hours , at temperatures of up to 400 degrees Celsius .
Additionally , high-temperature grease is essential for optimal bearing performance . Mobil Polyrex™ EM Series greases are specially crafted for electric motor bearings , employing advanced thickener formulation and proprietary manufacturing techniques to enhance bearing longevity and protection , particularly for ball or roller bearings operating at elevated temperatures .
This specialisation is paramount in ensuring the safety of occupants and minimising property damage in the event of an emergency . Such a capability is achieved through
The WEG W22 Smoke Extraction motors are meticulously designed to operate flawlessly even in the most challenging conditions , such as during a fire emergency .
rigorous testing and adherence to the highest industry standards , earning the W22 Smoke Extraction motors the coveted Applus + approval from laboratories in Spain .
In the event of a fire the motors must continue running for at least two hours to allow evacuation and firefighting operations .
The motor boasts a Premium Efficiency ( IE3 ) rating , signifying exceptional energy performance . It features advanced cooling methods including two types of enclosures , Totally Enclosed , Air Over ( TEAO ) or Totally Enclosed , Fan Cooled ( TEFC ).
The motors have various mounting options with foot mounted and pad mounted being the most common . Operating at a wide range of outputs ( 0.18 to 900 kW ) and offering various pole configurations ( 2 to 8 ), it adapts to diverse industrial needs .
“ The W22 Smoke Extraction motor ’ s capacity to withstand extreme temperatures , coupled with the WISE ® insulation system , allows for reliable performance even under demanding conditions ,” said Anil Kumar . “ Furthermore , its compatibility with frequency inverters promotes substantial energy savings , making it a sustainable choice for ventilation and circulation systems . This is particularly significant in a development as expansive and multifaceted as Dubai Hills Estate , where safety is paramount .”
