Drying Solutions

Frequently referred to as Industry’s ‘Fourth Utility’, there is no question that compressed air is extremely versatile and widely used. In fact it is absolutely necessary for many industrial processes such as powering instrumentation, control units, hand tools as well as to drive processes in thousands of applications.

However it does have its problems, particularly when inappropriately used.

Compressed air - the downside

Compressed air is expensive to produce. It can be as much as 30% of a total sites electricity usage. It can also be very wasteful, and as little as 8-10% of the electricity used is converted into usable energy. In addition, many systems waste around 30% of their compressed air through leaks, poor maintenance, poor control and often poor application planning.

Huge savings can be achieved by avoiding the inappropriate use of compressed air. Too often it is considered and regarded as a ‘free resource’ by companies totally unaware of the real cost to the business.

Of all applications with compressed air, drying is the least efficient. Apart from the energy consumption and the cost of filtering oil and condensate, the maintenance costs for a continuous operating compressor can increase considerably.

An optimized system should guarantee an efficient blowing capacity at a minimal cost and with a minimal environmental effect.You will be able to work more competitively with fewer production stops and a higher efficiency.

Advantages of an airknive system compared to a compressed air system

Airknive drying system

Compressed air

  • Low energy consumption

  • Safe: Pressure lower than 0.25 bar
  • Limited noise level
  • Little maintenance necessary
  • Efficient for large pieces
  • Production of large air volumes
  • High energy consumption
  • Pollution risk of components due to oil in the compressed air
  • May be dangerous due to the high pressure
  • High noise level
  • Extensive maintenance
  • Inefficient for large pieces
  • Insufficient for the production of large air volumes
