Screw compressor 30 kW: Redundant solution for food production

In food production, every minute of downtime counts. SCC air compressors has already successfully solved this problem in previous food applications in France (with the company Feuillette). Based on this experience, a concept was developed for the German customer in close cooperation with Kronwald Druckluft- und Kompressorentechnik GmbH – our premium partner from Bremen – that completely redefines redundancy, efficiency and maintainability.

The challenge: Dependence on two machines in full operation

A leading food company in Germany was facing a classic production bottleneck. Two older screw compressors – one with a fixed speed, one speed-controlled – were running continuously at full load to meet the demand for compressed air from the modern production plant. The consequences were clearly noticeable: hardly any reserves in the event of breakdowns, considerable operating noise that put a strain on the staff and, above all, production downtime was unavoidable during scheduled maintenance. This is not a viable scenario in the food industry, as downtime means lost production and potentially critical supply chain disruptions.

The solution: Two STORM 30 screw compressors in intelligent alternating operation

The answer to these requirements was clear: a switch to two STORM 30 screw compressors from SCC air compressors. The concept is for the two machines to share the compressed air requirements, not compete with each other. In normal operation, only one STORM 30 runs with a capacity utilization of around 60-80 %; the second machine is in standby mode, fully available. The compressors change roles every twelve hours – this results in balanced wear and maximum service life for both machines.

The highlight: maintenance work can now be carried out during production. While one compressor is being serviced, the other continues to run without interruption. This redundancy has significantly increased production reliability – an improvement of 50% to 100% availability is a measurable strength for the customer.

One of the most persistent problems was also eliminated: the new system is noticeably quieter in operation. The 30 kW STORM with its noise level of 65 ±3 dB makes a considerable difference – especially because only one machine is running under load. A noticeable gain in working comfort for the staff.

When designing this compressor system, it was clear from the outset that compressed air hygiene was non-negotiable. The German food processing company therefore opted for SCC-FOOD – the food-compatible oil from SCC air compressors. This oil is specially formulated for applications where potential product contact can occur. It meets the high standards of the food industry and gives the company the certainty that the highest compressed air quality is guaranteed.

The use of Kronwald as the implementing partner – an experienced specialist in compressor technology – ensured not only a technically optimal installation, but also the smooth coordination of all components. The result is a system that works reliably and is easy to maintain from day one.

Efficient food production: alternating operation and low energy consumption

The alternating operation concept brings additional benefits beyond pure redundancy. If only one STORM 30 is running at 60-80 % continuous load – instead of two older machines at full load – energy consumption is demonstrably reduced. The STORM makes optimum use of its efficient, direct-drive compressor, which permanently reduces operating costs. For the customer, this means long-term cost-effectiveness without compromising on performance or reliability.

The large compressor stage of the STORM 30 with its slow operating speed also contributes to the longer service life of all components. The high separation efficiency of the integrated oil separation system – combined with the SCC-FOOD oil – guarantees that the amount of residual oil in the compressed air remains minimal. This achieves a double effect: optimum air quality and reduced environmental impact.

Frequently asked questions about redundancy solutions in the food industry

Why is redundancy crucial for compressor systems in the food industry?

Food companies work under strict regulatory requirements and must ensure continuous production. A compressor failure not only means downtime, but potentially spoiled goods, delivery commitments at risk and costly upheaval. Redundant systems with alternating operation eliminate this risk. With two independently operating units – one of which is always available on standby – a safety fallback level is created that is indispensable for professional operations.

How does speed-controlled operation support energy efficiency and wear protection?

With the STORM 30, the speed control (VSD technology) ensures that the machine always adapts its output precisely to the current compressed air requirement. In alternating operation with a partner machine in standby mode, this means: The running compressor almost never requires its maximum output. At 60-80 % utilization, the motor works much more efficiently, generates less heat, reduces wear and tear and lowers power consumption many times over compared to a machine that is constantly running at full load.

What role does food-grade oil play in applications with potential product contact?

Food-grade oils such as SCC-FOOD are specially developed to leave no harmful residues in the event of direct or indirect contact with food. They meet strict food law standards and often also the requirements of certification programs (e.g. Food Safety Compliance). Their use not only signals technical expertise, but also responsibility. For food companies, this is a fundamental sign of trust.

Summary: Food production without compromise

Switching to two STORM 30 screw compressors has meant a qualitative leap for this German food processing company. Higher production reliability, lower operating costs, maintainable without production downtime and absolutely quiet – these are the tangible results. The alternating operation concept is not just a technical solution, but a business model for modern, sophisticated production.

SCC air compressors and its partner Kronwald Druckluft- und Kompressorentechnik have thus proven that a well thought-out compressor system – based on proven screw compressor technology and specialized industry knowledge – can significantly increase efficiency and reliability in the food industry.
