Type 8880 – Modular Tank Pressure Controller
The Bürkert pressure control system for containers is ideal for maintaining a defined pressure in containers containing air, nitrogen or other gases to protect the product in closed processes and especially in hygienic applications. Application examples: Gassing (inerting with gas), control of fermentation processes, transport of special media (time-pressure filling, buffer container) and much more. Two control valves work in combination with a pressure transmitter in a closed control loop. The goal is to maintain a constant pressure in the containers during filling and emptying or during fermentation processes.
จุดเด่น (Product Highlights):
- Various variants available for different hygiene requirements (self-draining, CIP and SIP capable, electropolished surface, FDA, dead space reduced)
- Flexible for different process conditions
- Automatic stand-alone solution
- Permanent process monitoring
- Fast cleaning
