Oil-free compressor SCROLLI 2 in a container: Oil-free compressed air for dental technology

A dental technology company was faced with a special problem: a milling machine needed to be supplied with high-quality, oil-free compressed air, but there was not enough space in the company building for a conventional compressor station. The solution was a customized container solution with the SCC SCROLLI 2 oil-free compressor.

Problem: lack of space and high quality requirements

The dental technology company needed a reliable compressed air supply with special quality requirements to operate its milling system. The only available installation site was in the company’s garden and was difficult to access. The specific requirements included

• 100% oil-free compressed air in accordance with ISO 8573-1 class 0 for the dental sector
• Pressure dew point of at least +3 °C to prevent the formation of condensation
• Space-saving installation due to the available space
• Maintenance-friendly solution despite difficult-to-access installation

Oil-free compressed air is essential in the dental sector, as oil contamination can impair the precision of milling processes and jeopardize the durability of dental restorations.

Solution: SCROLLI 2 oil-free compressor in customized container

The solution was developed in collaboration with Kronwald Druckluft- und Kompressortechnik GmbH from Bremen, a company specializing in compressed air technology and compressor systems

SCROLLI 2 oil-free compressor:

• 2.2 kW output at 0.24 m³/min flow rate (8 bar)
• Oil-free scroll technology with ISO 8573-1 Class 0 certification
• Compact dimensions of 750 x 635 x 852 mm with a weight of only 150 kg
• Low noise emissions of only 49 dB(A), ideal for residential areas

Container solution:

• On-site assembly of the container by Kronwald Bremen
• Integrated compressed air treatment with dryer and filter systems
• Weather protection for all components
• Accessibility for maintenance work despite garden installation

The scroll technology of the oil-free compressor offers particular advantages: By dispensing with intake control, every compressor revolution is dedicated to generating compressed air, ensuring maximum energy efficiency with no idle times.

Result: Optimum compressed air supply with added value

The implemented solution offers the customer the following advantages:

Operational safety

• Reliable 24/7 availability of the compressed air supply
• Modular design with automatic redundancy for multiple scroll units
• Intelligent multi-level SCC control for optimum operating mode

Quality assurance:

• 100% oil-free compressed air protects dental materials and milling tools
• Constant pressure dew point of +3 °C prevents condensation

Space-saving and easy to maintain:

• Compact footprint thanks to container design
• Protected outdoor installation
• Easy accessibility for service work
• Minimal vibrations thanks to scroll technology

Energy efficiency:

• No idling costs due to continuous compressed air generation
• Optimized power adjustment through multilevel control

Q&A: Frequently asked questions about the solution

Why is oil-free compressed air indispensable in the dental sector?
Oil contamination can impair the adhesive bonding of composites and ceramics and prevent precise retention patterns during preparation. In addition, oil and moisture promote the proliferation of bacteria in the system.

What are the advantages of a container solution?
Containers offer weather protection for all components, allow flexible installation even in areas that are difficult to access and still guarantee a maintenance-friendly solution thanks to integrated access options.

How energy-efficient is scroll technology?
With oil-free compressors, every revolution is used to generate compressed air – without idling times and therefore without idling costs. The multilevel control also optimizes energy consumption.

Are scroll compressors high-maintenance?
Scroll compressors have low wear due to contact-free compression. The modular design also allows continued operation with other modules during maintenance work.
