Intelligent, systematic cooling

• Higher fan efficiency
• Lower power consumption
• Sound-optimized airflow

Sindelfingen/Nuremberg, 14.10.2014. Long-standing company BITZER has optimized its ECOSTAR condensing units, further increasing the efficiency of the refrigeration system. The compressor specialist is presenting the new compact LHV7E models at Chillventa 2014 from October 14 to 16 (Hall 4, stands 310 and 408).

The cooling capacity of the BITZER ECOSTAR series can be adapted by the speed control of the compressor and condenser fan in order to best suit actual requirements. Precise temperature control increases the efficiency of the refrigeration system and reduces operating costs.

By using an EC motor in the new LHV7E, the next-generation ECOSTAR, BITZER has increased the efficiency of the fan, while reducing power consumption. It therefore already exceeds the requirements of the Ecodesign Directive for energy-related products (the European Union’s ErP Directive), which goes into effect in 2015. The company has also optimized condenser efficiency with an improved minichannel heat exchanger. This technology makes it possible to significantly reduce the refrigerant charge, while the sound-optimized airflow ensures a low noise level.

BITZER has also improved the control software and evaluation of operating data: a data log measures the system’s 19 parameters every two minutes. This information is stored for four weeks and can be accessed via Modbus. The preinstalled monitoring system of the ECOSTAR constantly monitors the refrigeration system and automatically takes countermeasures if these are reached.
