MITEC produces air conditioning and filtering systems for industrial processes, where the ambient conditions have to be strictly controlled to ensure both the product quality and the health and safety of the operators, or because they are subjected to the observance of the environmental protection laws. In the cleanrooms division dedicated to controlling particle contamination, there are two different operation lines which follow different approaches. Alongside the specific and “unique” situation which justifies the implementation costs, there is also the modular solution that exploits the use...

HARD WALLS IN ASSEMBLY KIT

Controlled contamination systems with a rigid boundary structure, suitable for the configuration and quality of the components with numerous uses up to IS4 class according to the ISO 14644-1 and GMP standards. Having overcome the plant concept, while maintaining the possibility of a customised system within the limits of the product, a “MACHINE-KIT” is formed which requires a much smaller investment, where all the components are integrated and divided in modules that are easy to assemble even by the end-user’s operators.

STRUCTURE MODULARITY Vertical wall panels form a perfectly level surface, with optimised pitch to achieve the required sizes, with a standard thickness of 50 mm, compound, polyurethane core, class 1 fire reaction and available in two types: STANDARD with facing in prepainted iron plate, colour RAL 9010, or in AISI 304 stainless steel, with fast hideaway couplings PHARMA with facing in plastic laminate 2.5 mm thick, WHITE or WHITE-GREY, with internal metal stiffening frame and male joint coupling. False-ceiling made with the same panels as the vertical walls, and double false-ceiling for ISO5...

MODULAR VENTILATION AND FILTERING SYSTEM Independent MTF AUT filtering-ventilation units made to the various sizes of false ceiling panels, and available in the different fittings. MODULAR AIR CONDITIONING UNIT Independent MAMC air conditioning units for cooling, heating, dehumidifying and humidifying installed on walls on the outside of the cleanroom. Made using independent single-unit direct expansion conditioners for indoor and outdoor use, with air condensation using the hermetic SCROLL compressors, the cooling, electric heating, condensation rack and fan units are installed together in the...

SOFT WALLS IN ASSEMBLY KIT

For the adaptability and limited costs, an important role is played in modular cleanrooms by the controlled contamination systems, where the boundary structure is made from an equipped ceiling supporting frame and flexible perimeter walls, formed of strips of transparent and matt plastic material. These sofwalls cleanrooms can be fixed or mobile, and are also supplied in kits, where all the components can be easily assembled, even by the end user. The simplified bearing structure is made from a series of hollow core sections, joined to each other by screws to form the longitudinal reinforcement...

The MTF system includes a family of absolute filter and laminar flow diffusion units, with their own fan, which are different for each setting, and used to prepare controlled contamination or sterile zones and rooms, classifiable according to ISO 14644 and GMP standards. The MTF units are suitable for use singularly to create small protected areas, or for decontaminated zones around operating machinery, or in series to create continuous ceilings, thus perfectly expressing the modular concept. The families all have their own specifically designed motor unit, with centrifugal impeller with backward-curved...
