Screw Compressors - Boge

The three main sections of the BOGE screw compressor(electrics & drive, compressor, independent cooling unit) are strategically aligned in the main cooling air flow: for maximum efficiency and service life.

Efficiency made easy:
According to our engineers, the design of the BOGE screw compressor is very much based on the principles of nature. High outputs, effective oil separation, and an extremely long service life of the component parts ensure that energy consumption is optimized.

Warm air rises:
Our engineers harnessed this simple law of physics in order to make BOGE screw compressors even more efficient and to prolong their service life. Cooling air is taken in at the lowest point in the package by a separate cooling air fan and is drawn over the component parts upwards before leaving the compressor at the highest point – our so called chimney effect. This main cooling air flow is many times higher than the actual cooling air flow of the integrated motor fan. Due to chimney principle, the system keeps cooling even during load reversal.

Efficiency advantage:
The intake filter is positioned in the coolest part of the cooling airflow and takes in the air for compression at the lowest temperature. This results in an optimized volumetric efficiency and output from the compressor. The air/oil cooler, on the other hand, is positioned at the top of the compressor. The cooler is generously dimensioned and, in conjunction with the cooling airflow, provides for the lowest possible internal cabinet temperature as well as discharge compressed air temperature. When connected directly to ducting, the cooling air can be removed without any problems or recovered and easily redirected to supplement space heating.

Service life advantage:
Motor, switch cabinet and all electric components are positioned at the intake of the main cooling airflow and benefit from the coolest air. As a result these components do not overheat either in load or in idle mode which means their service life is extended considerably. There are no heat sinks within the cabinet in either operating mode.

Oil always flows to the lowest point:
Therefore our engineers have positioned the oil pre-separator horizontally at the lowest point of the system. Also due to rapid reduction of the compressed air speed after compression bulk oil ”rains” from the compressed air into the reservoir – a most efficient form of oil pre-separation.

Efficiency advantage:
The BOGE oil separation system is designed to minimize internal pressure losses and to ensure a residual oil content of 1-3 ppm in every operating phase. The horizontal combi-tank ensures a low foam level at load reversal virtually eliminating the risk of bulk oil reaching the separator cartridges.

Long-life service advantage:
BOGE oil separator cartridges have a long service life – not only as a result of the highly effective oil pre-separation but also because of the large safety distance between the oil surface and the separator that prevents the oil from migrating into the separator cartridge.

Everything is cutting edge:
The BOGE airend is the heart of the BOGE screw compressor. Engineered to exacting tolerances, the BOGE airend combines quality and efficiency with long service life making it one of the best of its kind and a sound, long-term investment for our customers.

Maximum reliability
BOGE airends are manufactured on state- of-the-art production lines and are examples of the finest German engineering. Lowest manufacturing tolerances combined with quality materials ensures the dependability of each airend. Computer controlled testing further ensures that every single airend meets our high quality standards. The longest possible service life is also assured thanks to generously dimensioned axial and radial bearings.

Maximum efficiency
The screw profile of the BOGE airend has been optimized using the latest technological advancements providing maximum efficiency over the entire service life. We calculate the best possible specific power characteristics of each airend to ensure the best output per kW or HP while ensuring the airend continuously operates at its optimal speed.

The BOGE control and monitoring concept is your key to more efficient operation. We have the optimal control system for every type of application: from monitoring central machine parameters to specific synchronization of up to 16 different compressors.

FOCUS
FOCUS is the latest state-of-the-art energy efficient controller to come from BOGE. A large-scale LC display clearly shows error and maintenance messages, operating states and all operating parameters. (Additionally the operating status of a frequency controlled compressor and/or the workload of fixed speed compressors are displayed).

TRINITY
With the trinity controller from BOGE you can control up to three compressors of equal or different size or implement an automatic base load switching control. The adjustable base load switching cycle enables a constant load operation of all the installed compressors. trinity can be installed into the compressor switch cabinet or provided as a separate wall mounting cabinet version.

AIRTELLIGENCE
Airtelligence is designed to control up to 16 compressors of different makes and sizes in a multi-compressor system. It operates by selecting the appropriate compressor combination to meet the compressed air demand and to proficiently configure your system to ensure best possible operating efficiency: load/idle run switch cycles are minimized and expensive idle run times virtually eliminated. airtelligence: For a cost-effective and safe operation!

AIRTELLIGENCE PROVIS
Seeing is believing: airtelligence PROVIS synchronizes up to 16 compressors and visualizes the central parameters. As a result energy costs can be closely monitored via an interface to a web server where you can view this data at anytime and anywhere around the world.

Energy costs need not go off course:
because BOGE’s energy efficiency solutions offer a number of options that save energy. It is calculated that energy costs account for around 75 percent of the lifetime costs of compressed air generation. This makes energy optimization essential for any compressed air user. Significant sustainable savings can be created by continually auditing and optimizing your installation. You should therefore rely on a partner who, as an energy expert, is ready and able to support you before and after your decision to purchase compressed air products.

Perfectly controlled output: BOGE frequency controlled screw compressors

When there is a fluctuating compressed air demand, the BOGE frequency controlled screw compressors works strictly in accordance with the compressed air demand by producing the exact volume of compressed air at the pressure required.
The volume flow is continually adjusted between 25 and 100 percent – correctly specified frequency controlled compressors should eliminate expensive idling times and even out air demand fluctuations. Energy costs can therefore be reduced considerably. When a frequency controlled compressor is used alongside a fixed speed compressor additional advantages can be achieved. The flexible speed adaptation of the airend also allows for pressure adaptation. Changing the pressure value of the frequency compressor automatically synchronizes the output quantity. A 190 psig machine can therefore be transformed into a 125 psig machine yielding a correspondingly higher output – without any expensive remodeling or design related modifications. All pressures and intermediate pressures are available with the best possible outputs. It takes little or no investment for a compressed air user to save as much as 30 percent of their compressed air related energy costs. Be sure to take advantage of BOGE’s energy efficiency solutions to save energy costs. Examples:

Leak detection
A single 1/4" diameter leaking hole causes losses of 122 cfm – this equates to several thousand dollars a year of energy costs. Comprehensive leak detection from BOGE will identify any leaks within your compressed air network.

Heat recovery
Most of the energy used to generate compressed air is rejected in the form of heat. This heat can be recovered: e.g. for space heating or for the heating of domestic water. Up to 85 percent of the input electrical energy can be recovered: Our energy experts will be pleased to advise you! AIReport Does your compressor station still meet your specific site requirements?
