Press Release of March 2005   GEA air treatment units MultiMAXX with a new face – Prototype is completed Air treatment units with optimised technology and modified design – A prototype of the new MultiMAXX New Generation will be presented at the trade fair. Well-tried attributes such as the secondary air louvers will continue to provide top comfort. A generation change for the air treatment units of the GEA MultiMAXX product family: GEA Air Treatment is progressively revising and technically upgrading the entire product line. MultiMAXX units serve to ventilate, heat, filter and cool the air in business and industry premises as well as in showrooms. This system operates in circulation or mixed air operating mode and tempers the air with integrated heat exchangers. The robust units are mounted on the wall or the ceiling. First of all, the developer has produced a successor for the previous types M3, M5 and M7, which will come on the market by May. The new MultiMAXX covers an extensive performance spectrum and provides a number of capacity ratings. The model size 5 is new with an air flow rate of up to 12,500 m³/h and a heat output of more than 100 kilowatt. A greater deployment range is expected for the new MultiMAXX with combination options of components (intake and outlet attachments, engine variants and heat exchanger). The development engineers achieved improved power characteristics with optimised heat exchangers. The new air treatment units furthermore offer high variability in the media connections. The developers also improved the appearance of the MultiMAXX: The design is even more appealing and the unit is now available in various colours. The new control GEA MATRIX is already integrated in the MultiMAXX units of the new generation. This allows the air treatment units to be operated and monitored in combination with all GEA products. A global building automation system can therefore be inexpensively and universally implemented, and enhancements and modifications can be implemented without difficulty. The secondary air louver is already well known from predecessor units. It optimally blows in the supply air; the position of the air-directing lattice influences the air speed and the exhaust air temperature of the total air stream. With this technology, GEA achieves great casting distances and a rapid warming of halls or showrooms. At the same time, small temperature layering (0.2 K/m) and air velocities (0.2 m/s) are attained in common areas for optimal configuration. The results: the comfort zone is significantly greater in comparison to conventional air treatment units without secondary air louvers. Warm air is not concentrated below the ceiling but is distributed uniformly throughout the room. A hot head and cold feet are complaints of the past in commercial and industrial surroundings. By the end of 2005, the MultiMAXX special editions should also be revised. This is the specialist M4 stainless steel unit (for aggressive environments or for hygienic deployment) as well as the M4-Ex (for deployment in explosion-protected areas)and M6, the "powerhouse" for high air-side pressure requirements or great air volume. These special editions are available in their previous form up to final model change. The ceiling units MultiFlair M1 and M2 for exhibitions and sales areas as well as the warm air-curtains MultiMAXX MT remain unchanged for the time being. New design and improved technology: at the ISH trade show, GEA Happel Air Treatment presents the prototype of the new MultiMAXX air treatment units. The series production should start in the second quarter of 2005. A glance into the interior: inside the air treatment units numerous innovations have been implemented, for instance the optimised heat exchanger. Predestined for exhibitions and sales areas: the well-tried air treatment units MultiFlair (here the model MultiFlair M1) will be available in the future.
