INFINITE CAPACITY CONTROL • HIGH SEASONAL EFFICIENCY • PROVEN RELIABILITY
Chiller design incorporates compact screw compressors with mechanical capacity control: the cooling capacity controlled by a slider, which allows an adaptation of the compressor displacement to the power requirement by shifting the start of the compression process through the axial movements of the control slider. The slider, starting from the full load position (100%), can be infinitely adjusted to a nominal of 25%. Resultant seasonally weighted energy efficiency is high, exceeding industry standards for screw compressors.
The perfect match of refrigerants and compressor guarantees stable operation under extended operating limits with higher pressure ratios and lower condensing temperatures compared to earlier compressor generation. Robust, low-vibration design of the compressors contributes to long chiller service life and minimum maintenance costs.
