Soft Start
YVWH provides a soft start without current shock . The startup current will never be larger than the rating current , which benefits the customer with lower cost on associated equipment and smaller backup generator and quick start function in case of the shutdown due to power supply failure .
Displacement Power Factor ( DPF )
The Variable Speed Drive ( VSD ) design makes 0.95 high DPF achievable in standard YVWH models at all operating conditions . For traditional non-VSD designed screw chiller , the DPF will reduce when the cooling load goes down .
