MAICO's EU-wide patented ZITT system for modernizing belt-driven ventilation systems makes it possible to optimize energy efficiency and significantly reduce energy consumption. Ventilation systems improve the air quality in closed rooms by supplying fresh air and removing stale air. Air exchange in production halls is carried out by large fans, which are often driven by outdated motors. With the innovative ZITT motors, users save up to 60 % on energy costs. A study by the Lucerne University of Applied Sciences and Arts also confirms that the ZITT system is demonstrably up to 10 % more energy-efficient than comparable refurbishment solutions from competitors.
Rapid amortization thanks to short conversion times and low material costs
During the conversion, the existing AC motors are replaced with the new drive system - consisting of compact permanent magnet synchronous motors and frequency inverters. The connected load can be reduced, as the integrated frequency converters of the ZITT motors usually enable a lower power level. The existing on-site fan itself is not replaced during the conversion and can continue to be used. The conversion time required is very short, which means that the interruption to ongoing operation is kept to a minimum. Due to the enormous energy savings and the significantly lower investment costs for the ZITT system compared to competitor solutions, the measure can pay for itself within two to three years.
Energy cost savings of up to 60 %
If the conversion is also converted to a demand-led control system using sensors, the option of infinitely variable volume flow control enables maximum savings of up to 60 %.
Commissioning the retrofitted system is straightforward and is carried out via Bluetooth or the web-based ZITT-Net. Maintenance during operation is also simple and can be carried out remotely. Parameters can be read out, changed and sent via smartphone using an app. ZITT-Net can also be used to provide remote maintenance assistance from ZITT headquarters at any time. The sustainable and efficient electric motors are available in five sizes from 80 to 160, which, in combination with the frequency inverters, cover 16 power levels.
Well-known reference customers such as the two largest retail companies in Switzerland, Migros and Coop, as well as the Swiss Federal Railways SBB CFF FFS are already benefiting from the savings made by the ZITT system. MAICO is now also offering the energy-saving ZITT motors on the German market.
