Protect Your Recipe and Your Budget: The New DSG Series Oil-Free Screw Compressor for the Food & Beverage Industry

In food and beverage processing, every detail counts. Compressed air comes into direct contact with products, packaging, and cleanroom environments. A single oil or particulate contamination incident can destroy product batches, trigger costly recalls, and harm brand reputation—all while rising energy prices squeeze operating margins.

The Solution: The new DSG series from KAESER. In this blog post, we explain how it provides food-safe, oil-free compressed air certified for rigorous food contact standards while lowering specific power consumption across the entire operating range.

Energy costs account for more than 70 percent of a compressor's total lifecycle expenses. To stay competitive in modern production environments, operators must focus on reducing running costs. The new DSG series has been specifically designed to elevate energy efficiency to a new level and significantly lower electricity bills.

• More Air per Kilowatt: Up to 10–13% higher volume flow and a 7–10% reduction in specific power consumption compared to previous models.
• Premium Efficiency: IE5 Permanent Magnet / Synchronous Reluctance drive options paired with sustainable water-jacket cooling deliver an extra 2% efficiency boost over oil-jacket designs.

A large portion of the electrical energy supplied to a compressor is converted into heat. In many facilities, this waste heat vanishes uncaptured into the surrounding air. In times of rising energy prices and strict sustainability goals, this represents a missed opportunity. The DSG series enables you to harness this thermal energy and reuse it efficiently across your plant.

• Free Hot Water: Integrated heat recovery options capture over 90% of electrical input energy as usable hot water.
• Process Reuse: Ideal for Clean-In-Place (CIP) washdowns, thermal sanitization, and boiler feed water pre-heating.

Food processing plants — such as industrial bakeries, mills, or powder processing sites—are among the most demanding operating environments for industrial equipment. Fine dust and flour particles in ambient air quickly clog heat exchangers, driving up maintenance overhead and reducing output. The DSG series overcomes these harsh conditions through an optimized cooling and maintenance design.

• Beat Dust-Driven Losses: Dust and flour particles in processing plants clog heat exchangers, reducing delivery volume by up to 5%. Easily accessible cooler layouts make routine cleaning fast, straightforward, and painless.
• High-Ambient Operation: Standard operating capabilities up to 45°C–55°C ambient temperatures keep production running reliably during hot summer months and inside warm plant environments.

When it comes to protecting consumers and safeguarding brand reputation, there is no room for compromise. Every component that comes into direct or indirect contact with ingredients must meet rigorous safety standards. The DSG series establishes new benchmarks in hygiene and material requirements, ensuring continuous process reliability from the ground up.

• FDA & EU Certified: Air-contact components feature FDA, EC 1935/2004, and EU 10/2011 compliant coatings and fiber-free dampeners.
• Lifetime Zero-Oil: The patented KAESER Sealing Air System (KSAS) reliably prevents gear oil leakage over time, complemented by extended food-grade lubricant change intervals of up to 18,000 operating hours.

Existing processing facilities rarely offer unlimited floor space for expansion. When modernizing or expanding production capacity, plant engineers often face the challenge of integrating higher-performing machinery within an existing footprint. This is where the compact design of the DSG series excels, allowing older units to be replaced seamlessly with future-ready technology.

• 8–9% Smaller Footprint: Scaled specifically for direct replacement of older competitor or legacy air units in high-density processing environments.
• Expand Capacity, Not Footprint: Increase compressed air capacity (+10–13% flow) without surrendering valuable floor space needed for processing or packaging lines.

Conclusion: With the new DSG series, KAESER unites maximum process reliability and uncompromised food safety with dramatically reduced operating costs. It is the ideal solution for plant operators looking to boost efficiency while maintaining the highest hygiene standards.
