Kaeser has announced the launch of its electric portable compressor range. The new Mobilair electric portable compressors deliver zero emissions and substantial savings in operating costs – wherever a power supply is available.
The new electric portable compressors from Kaeser, are powered by motors rated at 15–25 kW, and form part of the highly successful family of Mobilair M27, M31 and M50 compressors. From large building projects to city-centre sites or indoor operations – emission-free electric-powered portable compressors are exceptionally quiet and are significantly easier on the wallet than diesel units.
These machines are ideal for environmentally sensitive areas such as clean air zones or building sites near hospitals. They are also perfect for tunnel construction or as bridge compressors for industrial stations. On large construction projects, where power hook-ups are usually available, the electric compressors make even more sense, as electricity is generally much cheaper than diesel fuel. Another advantage: electric compressors cost far less to maintain.
Power consumption is kept to a minimum thanks to the inclusion of IE3 premium efficiency motors, which meet the IP55 enclosure and Class F insulation standards, as well as comply with and exceed prevailing Australian GEMS regulations for 3 phase electric motors.
The Mobilair electric portable compressors are equipped as standard with the advanced Sigma Control Smart controller and Kaeser`s patented anti-frost control. The Sigma control smart makes set-up and operation – such as pressure adjustments – quick and simple with an easy-to-read colour display and the anti-frost control protects tools from frost and corrosion.
The models are available with a choice of a rotational moulded polyethylene or metal enclosure and in both road-going and stationary versions. Flow rates range between 2 and 5 m³/min for pressures from 7 to 14 bar.
Kaeser has also introduced its latest generation M57 Utility portable compressor. Compact, convenient and cost-effective the M57 Utility is now configured for even greater flexibility thanks to a number of new design features. The latest generation M57 Utility retains all of the original series popular features, including its compact size – crucial for truck-mounting, upward expelling exhaust gas outlet and all-round intelligent design.
The unit is configured as standard for an impressive temperature range from -10°C to +50°C, whilst a version designed for even lower ambient temperatures is offered with pre-warming of the motor cooling water.
In addition to the proven and renowned 7-bar version, which up until now delivered 5.4 m³/min, a new model with a flow rate of 4.7 m³/min at 10 bar maximum pressure is now available and ideal for applications such as sand-blasting.
With the intelligent Sigma control smart (SCM) controller fitted as standard, pressure can be reduced down to 5 bar in precise 0.1 bar increments for perfect adjustment to on-site conditions. The appropriate pressure setting helps protect, for example hammer drills that operate at 6 bar for optimum performance, from wear. The colour display provides a convenient overview of all operating parameters, alarm notifications and upcoming required maintenance. Motor start-up is made easy with just the push of a button.
The service-friendliness of the Mobilair series has always been a key characteristic of all models in the range and this has never been truer than with the compact M57 Utility. The unit is designed in such a way that all maintenance points are easily accessible from the cargo bed side once the panels have been removed. Fuelling is performed from the front side. Operating fluids and liquids can be easily drained via externally mounted service connections without having to hoist up or lift the compressor unit.Also the low-positioned compressed air take-off taps and the metal cover protected operating panel. This attention to detail makes operation especially easy, particularly when the unit is installed on a lorry cargo bed. For even higher compressed air quality requirements, the M57 Utility can be optionally equipped with a compressed air aftercooler.
The Mobilair M 57 Utility portable compressor from Kaeser is available in two pressure stages 7 bar (5.4 m3/min) and 10 bar (4.7 m3/min).
