ALMiG Screw Compressors
ALMiG Lento Series
The ALMiG LENTO Series is an intelligently designed, oil-free, rotary screw air compressor package. The compressor package includes the rotary screw compressor, TEFC VSD main drive motor, filters, liquid cooler, stainless steel piping and water tank, cooling fan and controls for up to 145 psig air pressure. All ALMiG's rotary screw compressors are designed to maintain full compressor output during continuous operation without affecting the compressor life.
The ALMiG LENTO Series is designed and certified to meet the requirements of acc. CLASS 0 oil free air. High quality, 100% oil-free compressed air is required not only in the pharmaceuticals, food, electrical engineering and medical sectors; it is also used wherever top quality products are produced. Water, the most natural of all raw materials, is used in the compression process as a coolant instead of oil. This results in Class 0 air: clean and environmentally friendly compressed air that is completely oil-free. Using water also causes the air end temperatures to be extremely low. The ALMiG LENTO Series compressor also comes with an internal refrigerated air dryer that is perfectly matched to the compressor's output.

Details
-
1. Air end
- Single-stage, water-injected screw
- Water injected air end with high operation security and long rotor life time
- Male and female rotor without synchronous gear
- VSD direct power transmission of the electric motor to the air end with a 1:1 direct coupling
- Electrical drive through variable speed controlled VSD asynchronous motor with enclosure TEFC / IP 55, isolating class H, small size and high efficiency of 90 - 96% over the entire speed range.
- Water and dust proof.
- Integrated refrigeration dryer for compressed air cooling and for continuous fresh water production for internal water circuit supply. Thus, the required circulating water is produced by the machine itself and no external supply is needed.
- Air drying and cooling through integrated refrigeration dryer (pressure dew point 37 to 46 °F)
- For optimal biological and chemical water quality
- Closed water circuit without expensive water purification. No external water supply is necessary the machine will operate autonomous!
- Multistage separation for dry compressed air
- Efficient power transmission
- Energy savings!
- Reliable and almost maintenance free
- The ALMiG variable speed drive optimizes the operation of the compressor compared to a fixed speed compressor. Your process is protected from damage and downtime, and you will benefit from reduced installation, energy and maintenance costs.
- ALMiG microcontrollers contain a lot features as standard without any price adder. With the integrated sequencer for controlling up to 8 compressors no matter which brand they ready for lead/lag operation. Furthermore the system is ready for connection to a factory wide data bus.
