RELIABILITY
Designed for the most severe conditions
State of the art control
Logic enables corrective actions to keep chiller safely on-line making cold water where other chillers would trip off.
Example, in case of problem on cooling tower on a very hot day, controls automatically:
Finds the balance point
Continues to deliver maximum amount of chilled water without tripping off
Displays an alarm message of auto-limitation
