Hygienic Design for Compressed Air Applications

Clean Line CL03

The Clean Line valve system: more energy efficiency in production.

Rexroth Pneumatics offers a wide range of pneumatic components for the food industry

- Pneumatic valve system according to IP69K with an EHEDG certificate

- Compressed air preparation units and pneumatic cylinders made of stainless steel

- Complete pneumatic systems and stainless steel control cabinets

The stringent demands placed on equipment in the food and packaging industry necessitate components that fulfill specific requirements for hygienic design while ensuring process reliability. Rexroth Pneumatics provides pneumatic components for all areas of the food and packaging industry, even for wash-down and splash zone applications. The company has already set several milestones in the hygienic design of pneumatic valves, actuators, and compressed air preparation.

Pneumatic valve system according to IP69K with an EHEDG certificate

The Clean Line CL03 is the world's first pneumatic valve system designed in line with IP69K. It features a joint- and gap-free cover made of sturdy high-performance plastic that resists a wide range of chemicals. The system’s mechanical strength fulfills the highest demands while the direct connection to all common fieldbuses reduces wiring efforts. Its protection class makes it suitable for use in wash-down applications and allows it to be placed close to the actuators. This reduces tubing lengths, decreases dead volumes, and lowers compressed air consumption – a substantial contribution to more energy efficiency in modern systems.

Compressed air preparation units made of stainless steel

With the new maintenance unit MH1 with a hygienic design, Rexroth Pneumatics continues the consistent decentralization of pneumatics in the food sector. All components are made of corrosion-resistant stainless steel. Compressed air preparation directly in the food processing area considerably decreases tubing lengths and dead volumes, while improving energy efficiency. At the same time, the risk of contamination from non-food processing areas is eliminated. This allows users to create and maintain the highest air purity standards in the critical food processing areas.

Pneumatic cylinders – precise movements executed cleanly

Pneumatic actuators handle many tasks in food production – whether moving spools, lowering and raising filling nozzles, or portioning, Rexroth Pneumatics offers components that were specifically optimized for the requirements of the food processing sector. The acid-resistant steel of the ISO cylinder ICS-D1 is resistant to cleaning agents up to aggressive acids. This round cylinder with a hygienic design is particularly easy to clean.

Rexroth Pneumatics also combines hygienic design and enhanced performance data in the GPC Clean precision guide cylinder. The manufacturer consistently implements corrosion-resistant materials such as stainless steel and anodized aluminum in this guide unit, which has been specifically developed for the food sector. Designed according to hygienic principles, its surfaces do not contain any grooves or drill holes.
