Background:
In bottled water manufacturing, product safety and purity depend on the quality of compressed air. Air that comes into direct contact with the product must meet strict oil-free standards, as even the smallest trace of oil could impact water quality and consumer confidence.

Challenge:
The customer required a compressed air solution that could:
Guarantee food-grade oil-free air to safeguard product quality.
Provide continuous and stable air supply to support multiple high-speed bottling lines.
Improve energy efficiency and lower operational costs compared with their existing system.
Help achieve international food safety certifications and regulatory compliance.
Enhance the workplace environment with lower noise and reduced maintenance demands.

Solution:
To address this challenge, the customer selected the DENAIR DVWW-90W oil-free screw air compressor. Featuring an all-stainless-steel air chamber and ceramic-coated rotors, the system guarantees 100% oil-free, medical-grade compressed air. With a capacity of 90 m3/min, it ensures continuous, stable supply for multiple high-speed bottling lines. The compressor's modular design allows seamless integration across different production lines, while its intelligent multi-unit control system automatically balances air pressure according to real-time demand. This combination provides both reliability and efficiency for large-scale production environments.

Results:
Since implementation, the DVWW-90W has delivered measurable improvements:
Enabled successful certification under the latest ISO 22000 food safety standards.
Improved energy efficiency, reducing operating costs and environmental impact.
Lowered maintenance expenses compared with previous systems.
Reduced noise levels, improving workplace conditions and supporting employee health.

Conclusion:
By adopting DENAIR's oil-free technology, the bottled water producer secured a solution that ensures product safety, enhances operational efficiency, and supports long-term sustainable growth. This case demonstrates DENAIR's commitment to helping global food and beverage manufacturers meet the highest standards of safety, reliability, and performance.
