FIMA Maschinenbau GmbH develops specific hermetically sealed blower solutions designed to operate in conditions where total gas containment and process safety are critical factors. Through its HETICO® and MACOUCO® designs, the company offers technological alternatives that eliminate one of the main risk points in conventional rotating machinery: dynamic seals exposed to the atmosphere.
The HETICO® concept (Hermetically Tight Compressor) is based on integrating the impeller and drive within a single airtight casing. This configuration completely eliminates leaks associated with traditional sealing systems, which is particularly relevant in applications with toxic, flammable, corrosive or high-value gases. The MACOUCO® design introduces a magnetic coupling, allowing torque transmission without direct mechanical contact and maintaining total separation between the process gas and the exterior. This solution not only reinforces sealing integrity, but also significantly reduces mechanical wear and maintenance requirements associated with conventional sealing systems.
From an engineering standpoint, these types of design are particularly important in applications where fugitive emissions are not acceptable or where even small losses could compromise the safety, performance or economic viability of the process. This includes services in Oil & Gas (BOG, LNG, offshore), advanced chemical industry, cryogenic gases or installations subject to strict environmental regulations.
Additionally, the hermetic architecture contributes to higher operational reliability, by reducing the number of critical components exposed and simplifying interface management between the equipment and its environment. Overall, the combination of total containment, reduced operational risks and adaptability to severe environments positions HETICO® and MACOUCO® solutions as a strategic option in applications where process safety and gas integrity are priorities.
