As chemical compounds from the group of aromatic isocyanates, methylene diphenyl diisocyanates are normally mixtures of several constitutional isomers. They differ in terms of the positions of the isocyanate groups. MDI is one of the most commonly produced isocyanates worldwide and is a key raw material for the production of polyurethane, polyamide and flexible foam, insulating foam, and adhesives. FIMA supplies single-stage radial blowers for the production of MDI. Products include containment, air extraction, and exhaust gas fans. The machines are manufactured from high-grade materials and realized in sophisticated designs.

As world leaders (2010) in Zone 0 blowers, we are aware of the high risk associated with the conveyance of continuously explosive gases. In the conveyance of gases in Zone 0, the plant is constantly exposed to an explosion hazard. Thus, in light of this explosion hazard, safety is one of the most important aspects of our blowers. Our machines have type approval for explosion groups IIA, IIB, and IIB3. We cover T1–T4 temperature classes for the gas–air mixtures. Our blowers can be found in tank terminals as well as loading, exhaust air combustion, wastewater treatment, and flaring and landfill gas plants, among others.

During the closed process of liquid evaporation, the vapor is fed through our VARECO, where its temperature and energy level are increased, and then fed back to the process. Thus, its valuable energy is not lost. The self-contained process allows volatile liquids to be evaporated while valuable products are retained. Our VARECO is used in the chemical industry in recovery processes for alcohols such as isopropanol and methanol. One example of its application is in the production of biofuels.
