VSD OIL FREE ROTARY SCREW COMPRESSOR 250 KW 340 HP (OGWD-250VP)

WHY OIL FREE AIR

Compared with the oil lubricated compressors, EUROAIR oil free air compressors offer you benefits of lower consts and environmental compliance. But above all, only oil free compressors eliminate the risk to your business of oil contamination.

Eliminating Risk

We developed our oil free compressors especially for applications demanding the highest level air purity. Whether your activities are in pharmaceutical production, food & beverage processing, semi-con & electronics, no oil means no  risk of contamination, no risk of damaged or unsafe products.

Lower cost of ownership

EUROAIR revolutionary oil free technology reduces expenditures in three ways: by avoiding expensive filter replacements, cutting maintenance costs, and avoiding the costs of extra energy needed to compensate pressured drop in filters. These costs, although not apparent at the time of purchase, become significant and contribute substantially to the total cost of ownership.

Direct Energy Savings of 15% to 35%

  • World renowned frequency inverter is housed that brings an unprecedented level of energy savings;
  • Advanced Vector Control with dedicated motor has attained the industry’s best control capabilities;
  • Low load operation of a VSD compressor does not result in energy losses;
  • Load/no load transition losses are eliminated;
  • The precise pressure control of the VSD compressor allows for a tighter and often lower discharge working pressure, resulting in reduced energy consumption.
  • The soft rise in motor starting current from zero to full load without any damaging current peaks leads to an almost unlimited motor starting frequency (number of possible motor starts per time period without overheating). The continuously variable acceleration and deceleration reduces dynamic loading of moving parts.

VSD Application Microprocessor Based Touch Screen Control Panel

The simple-to-use automatic electric control panel continuously monitors and displays overall system performance status (including varyling frequency, speed and shaft power) with pro-active service indications, alarms for malfunctions and safety shutdowns. Advanced remote control as option.

 

Advanced Variable Speed Drive System

  • Built-in PID functionality
  • Limitation of operating time at low speed
  • PTC probe management
  • Auto-restart function with configurable response time
  • Underload and overload detection
  • Low-flow detection
  • Sleep/wake function
  • Power used, power-on time and motor run time

High Efficiency Inverter Duty Motor

Special attention is given to the electric motor, which is specifically designed for VSD operation (inverter duty motor). Bearings are protected against induced bearing currents and both motor and frequency inverter are perfectly tuned to obtain the best efficiency over the entire speed range.
