Innovative Air and Gas Compression Solutions by RIEM ITALY: Pioneering Efficiency and Reliability

By Germana Falcone

In the realm of industrial air and gas compression, RIEM ITALY emerges as a front-runner, showcasing over four decades of expertise in compressor component manufacturing, maintenance, and service. Specializing in rotary screw compressors for a broad spectrum of industrial sectors including Food, Chemical, Petrochemical, Pharmaceutical, Steel, and Automotive, RIEM ITALY’s offerings are not just products but embodiments of innovation and technical proficiency.

The Essence of RIEM ITALY’s Screw Compressors

At the core of RIEM ITALY’s product line are the oil-free and lubricated rotary screw compressors, critical in diverse industrial applications. These compressors are classified into single-stage, suitable for low-pressure output up to 3.5 bar, and two-stage versions, capable of delivering pressure up to 10 bar. A distinguishing feature of these machines is their ‘oil-free’ or ‘dry’ nature, meaning there’s no lubrication within the compression chamber, ensuring purity and quality of the compressed air – crucial for many industrial processes.

The construction of these compressors involves a cast iron casing with either water or oil cooling systems, depending on the machine type. Inside the cylinder (casing), the compression screws rotate, ingeniously designed to intake atmospheric air and compress it to the desired pressure.

Innovation in Lubrication and Coating

While the compression chamber remains oil-free, RIEM ITALY does not overlook the need for lubrication in other critical areas, like the timing gears outside the compression chamber. These are meticulously circulated using a gear oil pump, showcasing RIEM ITALY’s attention to every functional detail.

What truly sets RIEM ITALY apart is its patented treatment of compression screws. The screws are coated with a fluoropolymer-based layer, boasting anti-adherent properties, significantly enhancing performance and longevity. This entire rebuilding process is under stringent quality control, concluding with a certified functional performance test. This certification is not just a proof of quality but a testament to the exceptional craftsmanship and technical innovation that RIEM ITALY offers.

Energy Efficiency: A Cornerstone of RIEM ITALY’s Technology

A vital aspect of RIEM ITALY’s compressors is their energy efficiency. The relationship between specific energy consumption (KW) and output (MC) is key. RIEM ITALY’s compressors are designed to optimize this ratio, ensuring high efficiency. Instrumental findings suggest that this efficiency decreases with increased operating hours and modes, highlighting the importance of regular monitoring for optimum energy use.


RIEM ITALY stands not just as a supplier but as a partner in industrial efficiency and reliability. Their commitment to quality, innovation, and energy efficiency in air and gas compression solutions propels them forward, making them a true “Made in Italy” hallmark in the global industry. As industries evolve and seek more sustainable, efficient, and reliable compression solutions, RIEM ITALY’s expertise and innovative approaches in screw compressor technology position them as an indispensable ally in this industrial evolution.
