ALMiG

The ALMiG FLEX is a single-stage rotary screw compressor with oil injection technology, variable speed operation, standard low-sound enclosure, AIR CONTROL 3 microprocessor, totally-enclosed TEFC motor with reduced voltage starting and efficient 1:1 (no gear!) transmission. Maximum operating pressure is 190 psig. The compressor is designed for indoor and outdoor installation and carries a optional 5 year warranty.

Compared to a ALMiG VARIABLE the FLEX series comes with a reduced footprint and extremly low sound level for installations with limited space availability. The units are made for 460V and 230V operation.

Cooling Sysem: Air Cooled

• Unit manufactured in accordance with ASME, OHSA and CE standards
• Compact build for installation near walls; operation and servicing from one side
• Ready for connection and operation, fitted with all the required cooling, control and monitoring equipment
• Vibration-isolated, fluid-tight base frame for foundation-free installation
• Compressor assembly isolated from the base frame in terms of vibration
• Sound-insulated with dirt-repelling lining and cooling air control system for extremely low noise level
• In the housing integrated electrical control cabinet.
• VSD drive
  
• Colours light grey (RAL 7035) and sky-blue (RAL 5015)

The compressor is equipped with the following features:

• Electrical drive through variable speed controlled VSD asynchronous motor with enclosure TEFC / IP 55, isolating class H, small size and high efficiency of 92 - 95% over the entire speed range. Water and dust proof.
• VSD direct power transmission of the electric motor to the air end by means of a flexible clutch
• ALMIG intake regulator with intake filter for safe, fully unloaded start-up and efficient and economical operation
• Oil-injection-cooled compressor stage featuring high operational reliability
• Oil separator reservoir with great oil surface for optimum pre-separation; Oil drain through ball valve; generously dimensioned filler opening
• Oil separator cartridge for high compressed air quality with low residual oil content
• Oil and compressed air cooling through large-area cellular radiator for low compressed air outlet temperature; easy to clean
• Radial ventilator for optimum cooling and extremely low noise level
• Separate cooling air ventilator drive is reducing main motor load
  
• The main switch also performs the function of an emergency stop switch according to electrical standards

ALMIG variable speed technology

ALMiG was one of the first manufacturers introducing the variable speed technology to the market in 1999.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.

Protection from damage and downtime

Soft starts and stops protect your equipment. Reduced start currents result in smaller fuses, cables and energy bills. Controlled stops eliminate the risk of water hammer and other costly damage.

A built-in shaft power monitor and a unique Load Curve Protection function protect your process by immediately detecting any situation that could cause inefficiency or damage. Early warnings and safety stops allow preventive action.

Energy savings and optimized operation

The ALMiG variable speed drive regulates flow and pressure by continuously adapting motor speed. No energy is wasted and there is no unnecessary equipment wear.

Simplified maintenance

Should a drive problem occur a full status report will be generated. You can quickly identify the cause and take corrective measures. Maintenance is simplified thanks to a minimum of accessible mechanical parts and fold-out power modules.

ALMIG USA Corporation – Quality Assurance

All ALMiG products are tested in the United States prior to shipment to ensure high quality and reliability. The unit comes with a free optional 5 – year warranty program for coolers, motor, air end and controller
