BOGE has recently enhanced the popular small C series range of Screw Compressors up to 15 kW. The compact C 10 LDR to C 20 LDR are now available even quieter than ever before thanks to the introduction of the new super silencer hood, making this range ideal for point of use applications.

The BOGE C series Screw Compressors are already very quiet in operation emitting very low sound pressure levels. However, where an even quieter operation is required such as at point of use, BOGE has now introduced a sound insulation hood as an optional extra. This hood encloses the screw compressor creating a virtually silent operation at just 61 dB(A).

The BOGE C 10 LDR to C 20 LDR, Directly Coupled Screw Compressors are mounted on a Horizontal Compressed Air Receiver with a Refrigerant Air Dryer providing a complete Compressed Air Centre.

Part of the popular BOGE C series range of Screw Compressors, the C LDR range have proven to be the clear choice for small industrial users that require a reliable and efficient source of compressed air in a compact design. The C series compressors are space saving and extremely efficient generating High Free Air deliveries in continuous operation.

For Maximum Operating Dependability and Efficiency all essential components are integrated into the compact module, eliminating the need for pipework and reducing flow losses.

Additionally, from the summer of 2011 all BOGE screw compressors now come equipped with the Premium Efficiency Class IE 3 Motor, a requirement that does not come into force until 2015.

The directly coupled C series models up to 15 kW are highly efficient and extremely quiet in operation requiring only a minimum footprint. Available in the standard pressure of 8 and 10 bar. Output capacities range from 1.060 - 2.280 m³/min and motor power 7.5 to 15 kW.

BOGE recently launched the BC series converters that cost effectively assists the end user in efficiently producing absolutely oil free compressed air to Class 0 (ISO 8573-0) quality.

In industries such as; the PET sector, the food and drinks sector and the pharmaceutical and chemical sector, generating absolutely oil free compressed air is paramount. The ideal way to generate oil free compressed air is to use an oil free compressor. However, this can be an expensive option and quite often only feasible for large compressed air users. BOGE has recently launched the BC series converters which provide the ideal solution for efficiently and cost effectively generating absolutely oil free compressed air!

The BOGE BC Converter is installed directly downstream from the compressor and has been designed to make downstream oil penetration impossible.
Due to the innovative catalyst system, the BOGE Converter only produces ultra clean condensate and absolutely oil free compressed air according to quality Class 0 (ISO 8573-0).

The BOGE Converter catalyst system ensures the long hydrocarbon chains of the residual oil contained in the compressed air are split up into carbon dioxide and water - substances which are naturally present in the atmosphere. The catalyst material is stored as granulated and compact bulk material in a receiver and compressed air circulates around it. Simultaneously, both oil droplets and oil vapours are cracked which means that both compressed air and any resultant condensate are absolutely oil free.

The advantage for the end user is a cost effective solution to generating oil free compressed air with both purchase and operating costs lower in comparison to running an oil free compressor with a traditional treatment system.

The BOGE BC converters are very energy efficient operating with an extremely low energy consumption level between 0.01 to 0.005 kWh/Nm³. Additionally with no filter pressure loss either, operating pressure can be optimised.

With a service life up to 20,000 operating hours, maintenance requirements are kept to an absolute minimum. Additionally, because the converter does not require filtration, subsequent element changes are eliminated.

The BOGE BC Converters are available in 13 models.

BOGE has just announced the launch of their second generation SO series oil free screw compressors. The second generation models set new standards in the 110 to 255 kW performance class boasting higher efficiency, reduced sound pressure levels and a new service friendly layout. BOGE oil free screw compressors have long since proved their importance to compressed air users in critical applications such as pharmaceuticals, food and semi conductor industries or wherever absolutely oil free compressed air generation is prerequisite.

On-going product development has now led to the launch of the second generation air or water cooled SO series oil free screw compressors.

The cooling air flow of the SO -2 models has been substantially optimised. Intake air is drawn from the coolest area to help increase the free air delivery and additionally the minimisation of internal pressure losses has led to greater efficiency both which help to improve specific power consumption.

The SO -2 models are now equipped with a combined sound and pulsation absorber. An intelligent design and the use of powerful absorbing materials means the entire range operates with significantly improved sound pressure levels making the new SO series quieter in operation than ever before.

A further technical improvement is the addition of a condensate separator in the intercooler between the first and second stage airends. This improved separation means absolutely safe operation for the second stage in applications where there are low ambient temperatures or in situations where there is high humidity.

Improved access to the more intensive maintenance components has also been an important part of the SO enhancement; for example the oil cooler has been relocated from under the airend and is now located in the area beneath the intercooler and after-cooler.
The BOGE SO -2 series has been re-engineered to produce oil free compressed air at the highest level of efficiency and safety and the 8 models and 16 variations ensures there is a version to meet all requirements from 110 to 355 kW

Compressed air is widely used throughout industry, so much so that it is often regarded as the fourth utility. However, unlike electricity, gas and water, it is unique in that it is generated onsite rather than being delivered by an external service provider. Ultimately, this creates a situation where the quality of compressed air and the costs associated with its generation and subsequent use are solely in the hands of the user, including the level of contamination removal.

With companies across industry coming under increasing pressure to minimise costs, a reduction in both energy consumption, through lower compressed air usage, and effective, planned maintenance can play a vital role in protecting operating margins

To realise the full capacity of a modern industrial plant, compressed air quality must be kept consistent using correctly specified, installed and maintained filtration technologies to remove oil and water, airborne particulate, rust and pipescale, micro organisms and oil vapour.

Filter elements form the heart of every compressed air system. However, by their very nature, the filter element and housing restrict the flow of compressed air, thus reducing the available system pressure downstream and affecting the energy consumption of the filter. This system pressure reduction, often known as pressure loss, is typically measured between the inlet and outlet of the purification equipment, and recorded as a pressure drop or differential pressure.

As compressors generally require large amounts of electrical energy to produce a volume of compressed air at a given pressure, these pressure losses will be converted directly into energy losses and consequently to operational costs for the user

Regardless of which materials are employed, the filter media in coalescing and dust removal filters is constantly bombarded by high velocity dirt particles, while also having to withstand extremes of pressure, temperature and a variable air demand throughout their operating life. In addition, coalescing filters also have to contend with being submersed in acidic condensate, including oil and chemical additives from compressor lubricants, as well as hot water

Considering the importance of system performance and reliability, it is important to analyse the cost of filter element replacement against the cost of not replacing them, taking into account the risk of damaged equipment, increased downtime, emergency repair costs and contaminated or faulty product batches. What sometimes seems like a cost saving in the short term can turn out to be a costly mistake. Ultimately then, the sole reason to change filter elements must always be to maintain air quality and therefore it is always wise to follow the manufacturer's recommendations if this is to be achieved. Why compromise air quality for the cost of a filter element?

In order to offer the highest level of energy efficiency right from the start, all BOGE screw compressors will be equipped with the "Premium Efficiency" class IE3 electrical motors from the summer of 2011.

The International Electrotechnical Commission (IEC) has recently introduced the new standard EN IEC 60034-30 to harmonise international motor efficiencies. This standard divides motors into three efficiency classes - IE1 to IE3 - and regulates the various energy standards for electrical motors across the world. From June 2011, all new motors within the EU must as least meet the efficiency requirements of class IE2.

From January 2015 it will be mandatory within the EU that all new compressors are equipped with the premium efficiency class IE3 motors. Realising the benefits of this class BOGE has decided from the summer of 2011 to equip all BOGE screw compressors - and a large proportion of BOGE piston compressors - with IE3 motors as standard.

The real incentive is that higher efficiency motors save money. It has been commented that the purchase price of an electric motor is normally less than the cost of its electrical consumption over 30 days. When compressor life-cycle costs are calculated over 10 years the huge benefits and savings are clear to see.

Current EFF ClassificationNew IE Classification

EFF3 - Low Efficiency Level ----------- No Comparative IE Standard

EFF2 - Improved Efficiency Level ----- New IE1 level

EFF1 - High Efficiency Level ----------- New IE2 level

No comparative EFF standard --------- New IE3 Premium Efficiency Level

Energy Efficiency has been a core mission of BOGE for many years already and the decision to meet the 2015 IEC standards in 2011 not only provides customers with the highest efficiency motors and best possible energy savings but also the confidence that BOGE remains at the cutting edge in compressed air generation.

BOGE recently announced the launch of the S 40-2 BLUEKAT, an Oil-Lubricated Screw Compressor with a built in Converter that cost effectively produces Absolutely Oil Free Compressed Air for the small to medium sized compressed air user.

The ideal way to generate oil free compressed air is to invest in an Oil Free Compressor. However, the investment cost involved in this technology means that this is usually the route for the larger installations. BOGE recently developed BLUEKAT to offer a cost effective solution for the small to medium sized oil free compressed air user.

BLUEKAT is an Oil-Lubricated Screw Compressor with a built in Converter that completely removes Residual Oil Aerosols contained in the compressed air and breaks the hydrocarbon chain into carbon dioxide and water. The residual compressed air produced meets the quality requirements of ISO 8573-1 Class 1 but more importantly it has been tested and certified to meet the exacting requirements of Class 0.

A further benefit of the BOGE BLUEKAT is that traditional Condensate Treatment and disposal is eliminated, any residual condensate is clean water.
Irrespective of the intake air quality, the operating principle of the Integrated Converter is absolutely safe and a cost-effective alternative to traditional Oil-Free generation - tested and certified.

Available in the standard pressure of 8, 10 and 13 bar. Output capacities range from 3.71 - 5.01 m³/min and motor power 30 kW.

BOGE has recently extended the popular C series range of screw compressors up to 22 kW. The C 15 to C 30 provide a quiet, compact and efficient compressed air solution to the medium sized compressed air user, setting new industry standards in specific power and sound pressure levels.

The extended BOGE C series range has been engineered to generate high free air deliveries in continuous operation and in an incomparably efficient manner.

For maximum operating dependability and efficiency all essential components have been integrated into the compact module. This serves to eliminate pipework and to reduce flow losses.

BOGE has set new industry standards with these C series models in terms of low sound pressure levels - from 63-69 dB(A) - making them very quiet in operation as well as offering increased compressed air outputs.

The new models are also very energy efficient with the specific real demand for energy ranging from just 7.08 – 7.16 kW/m³/min (according to ISO1217AnexC/PN2 CPT2).

Due to its compact design space requirements are kept to a minimum. An installation surface of less than 1 square metre is sufficient.

For the ultimate energy efficient solution a heat recovery system can be added to the new C series models as an option. Up to 94% of the input electrical energy is dissipated through the cooling medium (air or water) and can be recovered for space heating or pre-heating domestic water.

The belt driven C series models up to 22 kW are highly efficient and extremely quiet in operation requiring only a minimum footprint. Available in the standard pressure of 8, 10 and 13 bar. Output capacities range from 1.36 – 3.62 m³/min and motor power 11 to 22 kW. The new range is also available with an integrated refrigerant dryer.

BOGE has just announced that their established range of oil free screw compressors now meets the API 619:2004 standard.

The BOGE SO series has long since been a popular choice for those sensitive applications where absolutely oil free compressed air is demanded such as in the chemical and pharmaceutical, food and drinks and semiconductor industries.

The petrochemical and gas industries can now also be assured that the BOGE API-SO series not only provides highly efficient and reliable oil free compressed air, but also meet the API 619:2004 standard.

The API-SO series from BOGE incorporates the same sophisticated design features of the standard SO series which ensure clean and efficient compressed air.

A two-stage BOGE airend is used which ensures very low specific power consumption. The shafts are sealed by a combination of special sealing rings and a two-stage labyrinth vented to atmosphere leading to optimum operational reliability.

Like all of the BOGE oil-free screw compressors, the API-SO series is divided into three clearly divided sections. The component parts are intelligently positioned along the cooling air flow for increased service life and prompt availability of compressed air. Control electronics, electrical components and motor are located in the coolest part of the machine.

Both airend stages are easily accessible. Because a separate air fan is fitted as standard an optional cowl cooler can be mounted directly on the compressor. As the discharge air is cooled, no additional discharge ducting is required which means the compressor can be installed according to individual requirements.

The API-SO series models are available either air- or water- cooled. There are 13 models and 31 variants available in the BOGE API-SO range of oil free direct driven screw compressors.

The API-SO series is available in the standard pressure of 8 and 10 bar. Output capacities range from 5.25 – 51.4 m³/min, motor power 45 kW to 355 kW.
