Busch Vacuum Solutions has announced the release of the COBRA NC 2500 C, now available in an air-cooled configuration. Billed as the world’s largest dry and air-cooled vacuum pump, this development responds to growing industrial demand for more sustainable and efficient vacuum technologies.
Developed and manufactured in Switzerland, the COBRA NC 2500 C integrates a closed-loop radiator cooling system that eliminates dependence on external water cooling. “This enhancement brings numerous operational and environmental advantages for industries that rely on high-performance vacuum technology, such as resource savings, flexibility in setup, and reduced operating costs,” according to Busch’s official release on July 9, 2025.
By removing the need for external water cooling, Busch positions its latest vacuum pump as a solution tailored for industries aiming to reduce resource consumption while maintaining performance.
Focus on Sustainability and Efficiency
Traditional large-scale vacuum pumps often require either oil lubrication or external water supplies to handle heat dissipation. These setups typically increase operational costs and facility complexity, particularly in regions where water quality or availability is limited. Busch’s air-cooled COBRA NC 2500 C aims to address both challenges.
The pump’s system incorporates an electric water pump, a closed cooling liquid circuit, an air/water radiator, and two high-efficiency electric fans. Together, these components form a self-sufficient cooling mechanism that not only saves water but also reduces the infrastructure demands of industrial facilities.
“This radiator, along with the two electric fans, functions as a heat exchanger,” the release details. The design reduces the dependency on municipal or facility water supplies, offering particular value in industries that already operate with closed-loop systems or in regions facing water scarcity.
For many sectors, including semiconductors, glass bottle manufacturing, and metal can production, efficient vacuum systems are critical. Busch’s new offering caters to these needs while aligning with rising sustainability targets set by governments and corporate ESG commitments.

Industry Context: Demand for Water-Free Cooling
The vacuum pump industry has been steadily moving towards dry and air-cooled systems as regulatory and environmental pressures intensify. Water conservation is a mounting concern, especially in areas dealing with drought or aging industrial infrastructure.
According to the International Energy Agency’s 2024 report on industrial water use, manufacturing and processing industries account for over 20% of global freshwater withdrawals. Technologies that reduce or eliminate water use in industrial applications are therefore gaining increased attention.
The COBRA NC 2500 C fits into this broader shift by not only offering water savings but also minimizing maintenance needs. Maintenance is limited to periodic coolant changes for the radiator and routine oil changes for gear units and bearings.
Applications Across Key Industries
The COBRA NC 2500 C is engineered for a wide range of applications. These include:
- Carbon capture systems
- Central vacuum systems for semiconductor manufacturing
- Tobacco production
- Glass bottle and metal can manufacturing
- Vacuum cooling
- Biogas processing
The breadth of application indicates Busch’s intent to position the COBRA NC 2500 C as a cross-industry solution, rather than a niche product.
