The Earthwise™ CenTraVac™ centrifugal water chiller with a Tracer™ CH530 chiller controller and purge system includes a unit-mounted, medium-voltage, across-the-line starter that is factory installed and wired. The controller helps improve chiller reliability and adapts quickly to changing conditions, according to the manufacturer. A service control panel interface connects the controller to a laptop PC. The purge, with its own noncondensables pumpout system, removes noncondensables from the chiller and has its own refrigeration system, automatic self-regeneration carbon tank, and adaptive direct digital controls, says the company.
