Planning freedom for decentral 

air handling 

In the planning of a decentral air-handling system, those exercising 

responsibility must be sure that carefully targeted 

and flawless solutions can be provided for simple as well as 

for highly specialized applications. And this is the reason why 

so many experts view the GEA MultiMAXX family as an absolute 

essential. 

Its name is program. Multifunctional application possibilities, 

application-specific materials properties, as well as demand-optimized 

air treatment components provide the guarantee for the 

most efficient and cost-effective solution. 

Even the operation of a high-efficiency energy-recuperation system 

is a matter without difficulty with employment of the complete 

GEA MultiMAXX Ergo system. For more detailed information

GEA MATRIX – intelligent control technology 

Just the right turn for the right room climate 

If requested, the proven GEA MATRIX control unit will be integrated 

into the GEA MultiMAXX at the factory. Your benefit: 

only completely tested equipment will be supplied to your 

construction site. 

GEA MATRIX is available in configuration levels 2000, 3000, or 

4000, with adaptation to the various possible applications. Most 

of the versions are provided with the GEA MATRIX.Net dualcable 

bus system as default, through which all GEA MATRIX 

units can communicate with each other. As a result, it is simple 

to implement daytime and nighttime switching actions, and to 

control pumps and collect error messages at a single point. GEA 

MATRIX can also be connected to higher-level bus systems. 

In addition, GEA MATRIX assures energy-optimized operation 

of the GEA MultiMAXX. By means of the summer compensation 

function, GEA MATRIX takes into account outside-temperature 

influences and therefore prevents energy-intensive climate control. 

Comprehensive control possibilities 

■ Control functions in various expansion stages 

■ Bus interfaces to other equipment units 

■ Plug-and-play functionality 

■ Energy-optimized equipment operation 

■ Equipment ready to operate 

■ Highly competent service 

■ Global add-on modules 

■ LON interface 

■ Service tools 

Hardware and software are developed entirely at GEA. As a result 

of close collaboration in the company, GEA engineers can 

systematically adjust the control system to match every component 

– and in turn optimally exploit the possibilities of the units. 

GEA support staff also profit from this arrangement by being 

able to quickly and expertly react in case of any questions. 

Numerous additional global modules are available as function 

expansions of the standard-version local connections of the MA- 

TRIX control system. Examples here are: intra-group operator 

panels and clock modules, modules for activation control of exhaust-air 

fans and chillers, expansion of analog or digital input 

and output signals, 0 … 10-V outputs for valves, and integration 

into a LON bus system in accordance with the LonWorks standard. 

All modules can be simply integrated via the MATRIX.Net bus 

system. In addition, the service tools MATRIX.PDA and MA- 

TRIX.PC can be used for parameterization, initial startup, maintenance, 

and data recording from the MATRIX control system.
