MULTI-GAS MONITOR DETECTS in OXYGEN-DEPLETED AREAS
that can solve many gas detection challenges of mining and confined space work. The durable detector doesn’t

require oxygen to detect gas, so it is always reliable when oxygen levels are low. It detects and warns against hazardous levels of combustible gases (LEL), hydrogen sulphide (H₂S), carbon monoxide (CO) & oxygen (O₂). It has a two-month continuous run time without recharging, so it can keep working when users depend on it most. The extended battery life comes from the use of low power photometric infrared technology for LEL measurement. The detector’s LEL sensor is immune to catalytic poisons and it fails to safe.
ulti Gas Clip Infrared is a technologically advanced, portable multi gas detector
sometimes they may forget to do so. The Multi Gas Clip Infrared helps solve this problem. Its extremely long battery life means the system can go a full two months without a charge, even without ever having to be turned off. If users shut down the detector nightly the battery can last up to four months. Instead of draining the battery with
archaic pellistor technology, it uses an IR source. This conserves power, so the battery lasts and lasts and lasts. The detector also eliminates the

need to frequently calibrate portable gas detectors. It can go 12 months without being calibrated. That saves time and increases efficiency. l

BALL MILL MOTOR for IRON ORE MINING
expedited it to an iron ore mine. It took only three weeks before the unit was commissioned on site. The customer had ordered a same-

size replacement of the original motor with identical electrical properties: 6,750kW nominal output and 6,600V nominal voltage. Few (if any)
enzel Elektromotoren has quickly adapted and tested a stock motor for a ball mill and
manufacturers keep motors of this size in stock. That is why such units are usually manufactured to order and typically take several months to be delivered. Menzel was able to flexibly fulfill
this order thanks to an exceptionally extensive and very varied range of stock motors. A star-connection 11kV motor was rewired for 6.6 kV delta connection. Adapter base plates were adjusted for the existing bore hole pattern at the installation site. The motor has been especially tailored to the mill application to ensure maximum availability. It is extremely robust and withstands dust and vibration over the longterm. In another recent case study,
Menzel supplied a three-phase squirrel cage motor for a mine operator in Burkina Faso.

period as low as possible, the mine operator turned to Menzel to obtain a dimensionally and electrically absolutely interchangeable motor for the old machine on site. All connection dimensions, even the connection cables, met the requirements and enabled an easy assembly.
Based in Berlin, Menzel has been
manufacturing and distributing electric motors for more than 90 years. The company specialises in the delivery of large electric motors, including special models, within the shortest possible time. The product range comprises high and low voltage motors, DC motors, transformers, and frequency inverters. l
