1/9

Quality feature no.1

Service friendly layout easy access

All BOGE S series screw compressorsutilise the same layout and design concept,harnessing the laws of physics.

The system has 3 clearly designatedsections.

The cool electrics and motor section,the service-friendly compressor sectionand the autonomous fan/cooler section.

Your benefits:Optimum ease of access to allcomponents nothing is obstructed.BOGE screw compressors need fewercomponents than conventional models;

this saves on service and spare partscosts and increases availability andoperating reliability. All maintenancework can be done quickly and fromone side, minimising maintenance costs.

Quality feature no. 2

Section 1:Electric and drive sectionDrive motor, switch cabinet and intake filterall sited in the cold cooling air intake area.

Your benefits:The motor and switch cabinet minimumIP 54 protection are continuously cooled.

This ensures the longest possible com-ponent life, which in turn increases theavailability of the compressor.By utilising the coolest possible intake air,BOGE ensures the highest possible free

air delivery for the user.

Section 2:The Compressor section

The compressor section is compact andeasily accessible. A horizontal oil separationvessel is at the lowest point, with a directlyflanged airend and multi-function intake

regulator mounted on top. A separatorhousing with final separator cartridge andminimum pressure valve complete thissection. The whole set is mounted on avibration damped sub-frame.

Your benefits:Direct flanging of the airend and oilseparator block eliminate the need forinterconnecting hoses.


Section 3:Cooling sectionAn autonomous fan/cooler assembly withorced air circulation sited at the top ofhe system in the cooling air exhaust is

coupled with a generously dimensionedafter-cooler assembly.

Your benefits:This is the only area where high cooling airemperatures occur. The chimney effect

designed into the system means that hotair automatically rises, leaving no hot spotsnside the package during standstill.The hot air can either be released directlynto the atmosphere or ducted away. Withhe ducting system, hot cooling air can be

exhausted to the outside in the summer orused for space heating in the winter.Thanks to a cleverly designed maintenancecover, the cooler can be easily cleanedwithout the need for dismantling.

Optimised cooling air circulationCooling air is drawn into the side of thecompressor and is exhausted upwards,utilising the laws of physics (hot air rises).

The cooling process actually causes aslight vacuum in the package, which sucks

the panels tightly against the frame.

Your benefits:The panels are sealed against the frame inoperation, which means that the optimumcooling air flow is guaranteed throughoutthe life of the compressor, ensuring aconsistently low compressed air dischargetemperature.Discharge duct work can easily be fittedto take away the hot cooling air. In winterthis can be utilised for room heating andin summer this can be ducted into the

atmosphere. Additionally, a super-silencinghood can be utilised to provide very lowsound pressure levels.


Innovative oil-separationThe cornerstone of the BOGE safety oilseparation system is the horizontallymounted oil separation vessel with thedirect flange mounted airend dischargelinked to the external spin-on final separatorcartridge.

Your benefits:A separation system with no pressurelosses which guarantees a very low residualoil content of only 1-3 mg/m3 in everyoperating mode. A spin-on separatorcartridge that lasts longer and reduces thedownstream treatment of compressed air.Both benefits prove the integrity of theBOGE oil separation design.

External oil separation cartridgeThe final oil separation cartridge ismounted on an external oil separator block.The spin-on cartridges can be quicklychanged without the need for special tools.The distance between the oil level in the

horizontal separator vessel and the spin-oncartridge, in combination with the intensiveoil pre-separation, guarantees minimumcontamination of the spin-on cartridgeesulting in a long service life.

Your benefits:Extended service life of cartridge

Very low residual oil content of only13 mg/m3

Reduced downtime due to easy changespin-on cartridge


Thermostatic oil control with integratedoil filter

The thermostatic oil control valve isinstalled in all BOGE screw compressorsand ensures optimum oil injectiontemperature, both in the start-up phaseand when the compressor is running.

The oil filter removes impurities from theoil ensuring long reliable service life.

Your benefits:Minimisation of condensation and dirt inthe oil means long intervals between oilchanges and maximised availability of thecompressor system.


5/9


Automatic GM drive systemPatent No. 44 13 422

All BOGE belt-driven screw compressorsretain constant belt tension in everyoperating phase, thanks to the patentedGM drive system, which automatically

compensates for the different forces ofmotor weight, start-up torque and runningtorque.

Your benefits:Maintenance free operation, with belt slip-page virtually eliminated, re-tensioning notrequired and little risk of dirt contamination.


Maintenance free multifunction intakeregulator

An ingenious BOGE development whichnot only hermetically seals as an intakeregulator but also allows a valve-less oilcircuit with no need for an oil stop valvenor a check valve. The BOGE multifunctionregulator design eliminates numeroushoses and connections found in conven-tional compressors.

Your benefits:Off load the BOGE system unloads toatmospheric pressure which means thatthere are energy cost savings in start up.

The multifunction regulator is intrinsicallysafe in operation which, means that in theevent of a breakdown it fails safe. Hermeticsealing ensures that there can be no oilvapour escape in blow down, which meansthat the compressor stays clean for years.

Electric motorBOGE only use standard high efficient,Class F insulated, IP 55 motors withgenuine power reserves.

Your benefits:High efficiency motors are more energyefficient which helps reduce power costs.Operating within power capabilities alsoprovides energy saving power costs.Running in the cool end of the packagealso increases operational reliability andavailability.


Air intake filterBOGE deliberately site the paper micro-filter cartridge air intake filter in the coolend of the compressor package. Thegenerously dimensioned housing helpsdampen intake noises. The filter cartridgeis re-usable and can easily be cleanedwithout any delay.

Your benefits:Optimised volumetric efficiencyby intaking the coolest airIntake noises virtually eliminated.Micro-filter protects the oil andairend from ingress of airborne dirt.


Internal pipingBOGE only use steel tubing with precisionhydraulic screw connections for all internaloil and air/oil pipes. There is only one hosein the entire system on the clean air side.

Your benefits:

No oil bearing hoses to deteriorate andfail or associated connections to leakproviding lifetime maintenance costreductionsInterior of system stays oil-free and clean.

Water coolingBOGE offers a water-cooled option above22 kW. In some ambient conditions watercooling could be the ideal option fordissipating heat and maintaining thecompressor efficiency.

Your benefits:Maintained efficiency in higher ambientconditions.


Proportional Control PROP-control(option)Proportional regulation controls the free airdelivery between 50 percent and 100percent at an absorbed power of between78 and 100 percent. A continuouslyworking throttle valve in the intake adjuststhe amount of intake air according to theactual demand.

Practical application casePROP-control prevents the compressorfrom cycling (switching on and off) wherethere is a fluctuating air demand. It workseconomically in the f.a.d. range between50 and 100 percent.

Frequency control F-control (option)

Frequency control regulates the f.a.d.between 25 and 100 percent with a powerconsumption between 28 and 103 percent.Output control is adjusted according to thecompressor speed.

Practical application case

F-control economically controls fluctuatingair demand in the case of reduced storagecapacity or a tight pressure band. It canbe used in a stand alone application or asthe peak load compressor in a multiplecompressor station.
