ULVAC CR Series Multi-Stage Roots-Type Dry Vacuum Pump

The ULVAC CR Series is an air-cooled multi-stage Roots-type dry vacuum pump developed for general industrial applications. Thanks to its oil-free pump body and non-contact rotor-cylinder design, it provides long-lasting, stable, and clean vacuum performance. With low operating costs, easy installation, and maintenance advantages, it offers a reliable solution especially for evacuating clean gases and processes containing water vapor.

Key Features

• Low operating costs thanks to air-cooled design
• Structure that does not require cooling water or nitrogen gas
• Efficient operation with low energy consumption
• Capability to pump water vapor with gas ballast system
• Clean and reliable vacuum environment thanks to its oil-free pump body
• Compact, lightweight, and easy-to-install design
• Structure compliant with international standards such as CE and cTUVus

Application Areas

CR Series dry vacuum pumps are used in applications involving clean gas and medium-level process requirements:

• Sputtering and evaporation systems
• Vacuum drying systems
• Freeze drying applications
• Industrial furnaces and process equipment
• Vacuum packaging and gas filling systems
• Laboratory and analytical instruments
• Vacuum applications for clean gases (air, inert gases)

Technical Advantages

The CR Series offers a wide pumping capacity range with CR16B, CR30B, CR60B, and CR300B models. Thanks to its simple and reliable design, it provides long-term operation with low maintenance requirements. It delivers stable performance especially in processes containing water vapor through its gas ballast feature, increasing efficiency in industrial production lines. Its compact structure and low energy consumption reduce total operating costs.
