PRODUCT DESCRIPTION

The rotary Screw air compressors from NEC are the backbone of various industrial applications.
The range of NEC rotary screw air compressors comes with high end designs , advanced features and technologies that offers cost effective , long lasting , reliable and premium compressed air solutions suitable for light to heavy duty altogether industrial applications. Like wise other products also .

All Our NEC Products are one of our best sellers . In addition of Good efficiency , affordability , premium quality and Customers rating products . Especially NEC designs and manufactures engineered to deliver maximum uptime and reliability with superior safety norms . The oil Compressors guarantee low energy losses and low air outlet temperatures while ensuring high reliability . Generally good quality products.

Further more NEC comes with Uptime Assurance which is all about giving customers peace of mind . By offering industries leading warranty , which warrants that its product and the components for its products will perform the purpose and function for which they are designed and intended for the periods of time indicated when used, serviced and maintained in accordance with NEC instruction and specification . Altogether good warranty Compressors .

BENEFITS

Benefits following , NEC Screw air compressors Rotary positive displacement machines , capable of high speed operation over a wide range of operating pressures and flow rates at high efficiencies. In addition screw air compressors are no valves or other mechanical forces that can cause unbalance . In fact this allows a compressor to operate at high speed while combining a large flow rate with small exterior dimensions .

Main advantage of using a rotary screw air compressor is that it can supply compressed air continuously . Also with minimum fluctuation in delivery pressure and generate less heat than standard air compressors . Which causes energy efficiency and also performance .

ADVANTAGES

  • Convenient and safe as they deliver air continuously for the required purposes and the causes of any accident are minimal.
  • Function at extreme temperatures from high to low temperatures and at any form of energy or temperatures.
  • Lower maintenance costs.
  • Long lasting as they have little or no capacity reduction.
  • These compressors are designed to run tools that generate more power than standard equipment.
  • Low noise output machine.
  • Minimum oil carryovers as low as three ppm in oil lubricated machine.
  • Following profile

PROFILE

  • Profile following
  • Consists of several segments of different shapes.
  • Large positive displacement increases the air’s pressure by reducing its volume.
  • A strong female rotor helps in tapping more air and reducing space continuously.
  • A short sealing line maintains a seal over the entire contact length, eliminating the need for a sealing strip.
  • Better clearance distribution.

PRINCIPLE

Especially the Screw air compressors uses a rotary type positive displacement mechanism. The screw element consists of two rotors similar to a helix, each with a different shape and also number of grooves teeth. Firstly Atmospheric air is sucked into this screw element and Secondly the air progresses along with the rotors , Finally it gets compressed air . In Addition main characteristic is a male and a female rotor element that brings the air to trap and release when air required .

  • Oil lubricated Screw type air compressor, the male rotor is driven by the motor or engine, and the female rotor is driven by the male rotor, or actually by the thin film of oil that’s between them.
  • Oil free Screw type air compressor a set of gears control the timing between the male and female rotor. There is no oil to seal the chamber.

WORKING PROCESS

The basic principle of a rotary type screw air compressor is that the male and female rotors spin in opposite directions. The prime mover turns the rotor of the air end in a rotary screw air compressor. This develops a vacuum which results in surrounding air being driven into the air ends through the air filter. As the rotors turn progressively, the air gets trapped in the spaces between the two screws (rotors).

Although Air is taken from the atmosphere into the rotary screw compressor through the air intake system. Firstly , it passes through a filter that helps in removing suspended particles from it. Secondly, the filtered air goes in the air end , the heart of the rotary screw air compressor. Another end here the air is trapped within the spaces between the two rotors with lobes that mesh with each other. Altogether as the rotors turn, they progressively compress the trapped pockets of the air, discharging the compressed air at the outlet of the air end .

NEC’s are good examples of best-in-class rotary screw electric air compressor technology, an ideal footprint for industrial applications. Further more application below as follows .

Industries like food, beverage, and textile use rotary screw air compressors for their operations. The rotary screw air compressors are used in various applications like food processing plants, breweries, etc. Food and beverage companies rely on rotary screw air compressors to keep their finished products fresh. Textile companies make use of these compressors for drying purposes. In addition farms commonly use them to run sprayers that work on liquids like insecticides , liquid fertilizers , etc., easily carried by compressed air. Above all noted are related to the Screw compressors .

AIR DRYER

Further we bring forth for our clients a wide collection of Air Dryer . Generally these Air Dryer manufactured at our state-of-the-art infrastructure facility. Especially Latest machines and advanced technology employed by our experienced professionals following standards and norms of the industry.

Basically Compressed air systems could be best sources for energy savings. On the supply side where air is compressed, it is vital to utilize the right combination of compressors, air receivers as well as air dryers. Using industry standard accessories will enable the system to run more efficiently and effectively.An air dryer is an integral part in the air treatment system. Selecting the relevant air dryer as well as compressed air filter is very critical.

NEC compressors air dryers are supreme quality treatment products that will considerably improve your entire air compressor system. Our extensive knowledge and expertise in this field is a key factor to the success of your compressed air system similarly . Air Dryer is most important for the pneumatic solution . Mainly Pre filters and following filters like After filter and Micro filters further to clear dust particles from the compressed air. Moreover Auto drain valve clean the moisture in the Air receiver . Further continuous stage of process make air purify . Consequently process will happen.
