Next-generation dry claw vacuum technology delivering oil-free, contact-free operation at vacuum levels previously associated with oil-lubricated pumps. CompreVac supplies and supports the Elmo Rietschle C-VLU range for demanding industrial vacuum applications.
High-vacuum oil-free claw technology supplied and supported by CompreVac.
The C-VLU extends dry claw technology into vacuum levels previously associated with oil-lubricated machines. CompreVac provides C-VLU application engineering, equipment selection, replacement pumps, parts and service support.
The Elmo Rietschle C-VLU uses a patented dry claw air-end design to achieve significantly deeper vacuum than conventional claw technology.
Two precisely synchronized claw rotors rotate without contacting each other or the compression chamber. This eliminates oil from the process gas path while reducing mechanical wear inside the air end.
The result is a high-vacuum machine capable of serving applications that have traditionally relied on oil-lubricated rotary vane or other more maintenance-intensive vacuum technologies.
The VLU combines the cleanliness and low maintenance of dry claw technology with significantly deeper vacuum performance.
Designed to reach vacuum levels previously difficult to achieve with traditional dry claw technology.
No sealing oil is required in the compression chamber or process gas path.
Synchronized claw rotors operate without touching each other during compression.
Selected VLU configurations are suitable for humid and wet industrial processes.
The VLU platform scales from compact high-vacuum machines to high-capacity industrial claw vacuum pumps.
The compact C-VLU 62 brings high-vacuum dry claw technology to smaller industrial applications where clean operation and low routine maintenance are important.
The C-VLU 122 increases available suction capacity while retaining the dry, oil-free and contact-free operating principle of the VLU platform.
The C-VLU 301 combines substantially higher pumping capacity with high-vacuum dry claw performance for industrial packaging, processing, automation and centralized vacuum applications.
The C-VLU 401 and C-VLU 501 extend the platform into higher-capacity industrial vacuum duties while maintaining dry, contact-free compression and high continuous vacuum capability.
The VLU uses a patented claw air-end geometry engineered specifically to extend the operating range of dry claw technology. Synchronized rotors compress the process gas internally without rotor contact or oil in the compression chamber.
VLU technology is aimed at applications that need deep vacuum but also benefit from avoiding oil contamination and frequent routine maintenance.
High-vacuum packaging applications requiring clean, oil-free compression technology.
Industrial vacuum for wet and humid process conditions in beverage production.
Vacuum generation for processing, handling and production equipment.
Clean vacuum generation where oil contamination in the compression chamber is undesirable.
Deep vacuum for extrusion, degassing, recycling and production machinery.
High-performance oil-free vacuum for automated machinery and production systems.
The C-VLU represents a significant extension of traditional dry claw vacuum technology, combining high vacuum with an oil-free process gas path.
CompreVac supplies Elmo Rietschle VLU high vacuum pumps with application engineering, replacement equipment, system integration, parts and service support.
For a new installation, CompreVac can evaluate required pumping speed, operating vacuum, duty cycle, moisture loading, filtration, system losses and controls to determine whether VLU claw technology is appropriate for the process.
The C-VLU is a new generation of dry-running rotary claw vacuum pumps designed to reach substantially deeper vacuum than conventional claw technology.
Selected VLU models are designed for vacuum levels around 29 inHg. The published VLU literature identifies applications as low as approximately 30 mbar absolute.
Yes. The compression chamber operates without oil being used as the sealing or working fluid in the process gas path.
The patented VLU air end allows substantially deeper ultimate vacuum than conventional dry claw technology while maintaining contact-free, oil-free compression.
Yes. Elmo Rietschle identifies the VLU range as suitable for humid and wet processes, with configurations available for demanding applications.
The CompreVac range shown here includes the C-VLU 62, C-VLU 122, C-VLU 301, C-VLU 401 and C-VLU 501 high-vacuum claw pumps.
The published C-VLU 301 datasheet lists nominal suction capacities of 156 ACFM at 50 Hz and 188 ACFM at 60 Hz.
In some applications it may. The VLU's deeper dry-claw vacuum range means it can be considered for duties historically served by oil-lubricated technology. Final selection should be based on airflow, operating vacuum and process conditions.
The dry compression chamber does not require routine process oil changes or oil-separator replacement, and the contact-free claw mechanism reduces internal wear compared with contacting compression technologies.
Yes. CompreVac can review required pumping speed, vacuum level, operating cycle, humidity, filtration and system conditions to help select the appropriate VLU model.
Yes. CompreVac provides application support, replacement parts, troubleshooting, field service and workshop repair for industrial Elmo Rietschle vacuum equipment.
