  Hybrid Permanent Magnet (HPM) Motor

  • High efficiency (95%) at all speeds and loads.

  • Unlimited Number of stop/starts per hour

  • Reduced maintenance costs.

  • Close coupled to the air end. No gear / belt drive losses, no couplings to fail.

  • No motor bearings: motor rotor is supported by extended air end shaft.

  • Field replaceable stator windings.

   

  Proven Ingersoll Rand air end

  • Features to provide long and reliable life:

  • Duplex tapered roller bearings for thrust loads on non drive end

  • Roller bearings on input end.

  • Bearing oil dams. Provides oil at bearings to provide lubrication during start up.

  • Triple lip shaft seal.

   

  Intellisys controller

  • User friendly LCD display

  • Monitoring and control of machine functions and operating parameters

  • Variable speed capacity control with short cycle stop/start operation at low demands.

  • Supports a remote pressure sensor (optional) for optimum system pressure control and energy savings.

  • A range of communications features for remote operation and monitoring

  • Built in energy saving audit tool to record power saved.

   

  Coolant system

  • Coolant Conditioner controls coolant temperature.

  • Large capacity oil coolers. Fully rated for 46^o C ambient operation.

  • Thermostatic oil control valve. Ensures the compressor runs at the right temperature.

  • Spin on type oil filter for easy maintenance. Removes particles to 5 micron.

  • Filter condition monitored by Intellisys

  • Oil Separator system. Multi stage, separator tank and element.

   

  Aftercooler

  • Air Cooled Radiator type.

  • Rated at 10 ^o C approach temperature for moisture removal .

   

  High efficiency cooling blower

  • Centrifugal type provides even spread of cooling air through the enclosure.

  • Variable speed operation based on machine temperature to minimize energy costs (90 kW and above and all 2 stage machines).

   

  Ingersoll Rand Ultracoolant.

  • Ultracoolant is not just a compressor oil. Ultracoolant is an engineered synthetic coolant specifically designed to help rotary screw compressors maintain peak performance at a range of operating temperatures.

  • Non-varnishing

  • Non foaming

  • High thermal conductivity: Ultracoolant absorbs more heat than other oils and will not varnish when heated.

  • Long Life – 8000 hours.

  • High Flash point

  • Biodegradable

  • Excellent cooling
