• How does the multi-step capacity control benefit our operational costs?
  The multi-step control (e.g., 0/25/50/75/100%) allows the compressor to dynamically adjust its power draw based on your real-time thermal load. This prevents the system from running at full capacity when not needed, significantly reducing daily electrical consumption.

• Is the equipment suitable for highly corrosive processing environments?
  Yes. Beyond the standard SUS304 stainless steel fluid pathways and outdoor-grade painted frame, we offer optional acid and alkali-resistant evaporators specifically tailored for chemical processing and electroplating facilities to prevent rapid degradation.

• What happens if there is an unexpected pressure drop or power phase issue?
  The chiller is equipped with an exhaustive safety suite. Upon detecting inverse phase, high/low pressure anomalies, or disrupted water flow, the PLC instantly halts operation and triggers an alarm, preventing any mechanical damage to the core components.
