Application Guidelines Single compressors Reinforced high grade cast iron scroll set. 2 ranges for high and low pressure ratio High speed oil circulation minimized by separating oil and gas flows with a sump oil return tube A patented oil injection system ensures optimal efficiency at low speed by improving scroll set sealing Lead free polymer bearing with excellent performance under diverse loads and speeds Oil injection control optimizes the oil circulation Permanent magnet motor with high efficiency at all speeds Oil strainer controls the risk of system debris in the oil injection...

Application Guidelines Inverter compressors Compressor size Inverter technology offers more flexibility in compressor selection than fixed speed compressors. Selection of the right inverter compressor size can be done by different methods: 1. Maximum cooling capacity: Select a compressor size which achieves the peak load system cooling capacity demand at its maximum speed. 2. Nominal cooling capacity: Select a compressor size which achieves the nominal system cooling capacity at a rotational speed of 3600 - 4500 rpm (60-75 rps). Single compressors 3. Best Seasonal Efficiency Ratio: Select a...
