Screw Air Compressor Series With Frequency Control

Product Details:

The SF series models in Screw Compressor are available in the following pressure ranges: 8 bar, 10 bar and 13 bar. Due to their continual flow regulation ranging from 25% to 100% they cover free air delivery in the range of 45 kW and 110 kW.

The SF series models have a frequency converter and separate control integrated into the switch cabinet in a space saving manner. The efficient control of the compressor is a standard feature in the SF series. The current operating conditions of the machine are displayed clearly and precisely in the LCD display.

SF series screw compressors can be ideally integrated into any existing compressed air station.

Screw Air Compressor With Vfd - Sdf (45Kw - 110Kw)

THE COMPLETE SOLUTION...SDF series frequency controlled compressed air stations with integral dryer Screw compressor (S) with integral dryer (D) plus frequency control (F).

The SDF series combines the many features of the SD range with all the energy saving benefits of frequency control.

• Integral dryer with integral frequency convertor provides a complete solution at a very competitive price
• Space-saving design
  - reduced footprint
  - costs for installation of separate dryer and convertor eliminated
• Dryer module is simply dropped into the top of the compressor package
  - fast and easy access
• Cyclone separator with condensate drain fitted before the dryer as standard
  - bulk condensate eliminated before dryer
• Dryer fitted with electronically operated, level-controlled condensate drain as standard
  - loss free removal of condensate
• High availability of the compressor
  - in the unlikely event of a dryer malfunction a simple bypass ensures continual availability of the compressor

ENERGY SAVING ...Tighter/reduced system pressure virtually eliminates off load running, in turn reduces start-up current peaks, and contributes to potential energy savings of up to 40 %

REFRIGERANT COMPRESSED AIR DRYERS...The frame mounted refrigerant dryer has a pressure dew point of +3°C (DIN ISO 7183) and simply drops into the top of the screw compressor cabinet enabling simple maintenance or removal if ever necessary.

EFFECTIVE FAD: 62 - 650CFM
PRESSURE RANGE: 8 - 13Bar

S-crompressor With Vfdew Air C - Slf (30Kw - 200Kw)

SAVING ENERGY & SPACE...HIGH OUTPUT WITH TOTAL CONTROL (SLF/SLDF SERIES 30KW - 200KW) Adjusting the motor speed to fulfil the varying free air delivery requirements is the most efficient operating method when the system has considerable fluctuations, limited air receiver capacity or when the compressor is operating as peak load compressor

REFRIGERANT COMPRESSED AIR DRYERS...The frame mounted refrigerant dryer has a pressure dew point of +3°C (DIN ISO 7183) and simply drops into the top of the screw compressor cabinet enabling simple maintenance or removal if ever necessary.

ENERGY SAVING...Tighter/reduced system pressure virtually eliminates off load running, in turn reduces start-up current peaks, and contributes to potential energy savings of up to 40 %

ADVANTAGES OF FREQUENCY CONTROL...

• Smooth starting and stopping within seconds
• Continuous volume flow control from 25 to 100%
• Flexible adaptation of free air delivery
• Reduced costs for wearing parts and maintenance
• No start-up current peaks (energy saving!)
• Constant net pressure +/- 0.1 bar (energy saving!)
• Almost no idle operation (energy saving!)

SLF/SLDF SERIES...

• Matches demand perfectly
• Controls pressure precisely
• Optional radial fan or super-silencing for significant sound pressure reduction
• Option with integral refrigerant dryer: the ultimate energy saving, space saving solution

The BOGE SLF/SLDF series combines a direct coupled drive system with frequency control to provide the ultimate compressor for pressure control under variable output requirements.
In this direct coupled series the frequency convertor assures the smoothest possible transition from 25-100% to maintain pressure and output perfectly.

An energy efficient RATIO control is also a standard feature of the SLF/SLDF series. The respective operating conditions are clearly and precisely visible via an LCD display.

The SLF series operates the airend within its optimum range and by changing the speed of both motor and rotor the compressed air output adapts to the actual demand. Expensive idling times and motor switches are avoided. At the same time a tighter pressure band can be set, also helping to save energy.

SPECIAL FEATURES.

• By adjusting the airend speed utilising frequency regulation not only adjusts the output (FAD) but can also adjust the pressure (bar).
• The SLF series compressors can therefore operate at 8, 10 or 13 bar pressures.

EFFECTIVE FAD: 37 - 1225CFM
PRESSURE RANGE: 8 - 13Bar

Product Details:

THE IDEAL OPERATING MODE...The frequency controlled CLF series automatically adjusts to the air demand whilst controlling the pressure perfectly. In the event of a change of the pressure value, the output automatically adjusts. For example a 13 bar machine regulated to an 8 bar yields a correspondingly higher output–without any expensive remodelling or design related modifications.

THIS IS AS EFFICIENT AS IT GETS (CF SERIES 15KW - 22KW)...With these frequency controlled compressors you can rest assure that lower compressed air demand translates into reduced energy consumption with the frequency inverter continuously adjusting the volume flow to the actual demand. This leads to minimised idling times and pressure fluctuations. Soft starting also avoids undue wear and tear and prolongs the service life of the compressor.

MAXIMUM EFFICIENCY...The BOGE C series up to 22 kW is characterised by its industry leading specific power ratios – for efficient compressed air supply.

FREQUENCY CONTROL...The optional frequency converter (CLF-/CLDF series) ensures a continuous volume fl ow between 25 and 100 percent. This allows adaptation to the momentary demand of the compressed air system. Soft starting also avoids undue wear and tear and prolongs the service life of the compressor.

REFRIGERANT DRYER...The CDF series include an integrated refrigerant dryer for extremely high compressed air quality.

CONTROL...The compressor is controlled by the FOCUS control system which includes an integrated effi ciency display as well as additional monitoring and control options. FOCUS is programmed as a changeover switch and can control up to three machines.

ECONOMICAL DUE TO FLEXIBILITY...By adjusting the airend speed utilising frequency regulation not only adjusts the output (FAD) but can also adjust the pressure (bar). The CLF machines can therefore operate at 8, 10 or 13 bar pressure without compromising free air delivered. To regulate a normal 13 bar compressor to 8 bar reduces the pressure but the output remains at the 13 bar design figure. The direct driven CLF, utilises frequency regulation in order to maximise FAD output whether at 8, 10 or 13 bar!

CLF SERIES...Direct coupled, reduces transmission losses to a minimum. The BOGE CLF series combines a direct coupled drive system with frequency control to provide the ultimate compressor for pressure control under variable output requirements.

The CLF series operates the airend within its optimum range and by changing the speed of both motor and rotor the compressed air output adapts to the actual demand. Expensive idling times and motor switches are avoided. At the same time a tighter pressure band can be set, also helping to save energy.
