Optional Feature – Redundant Primary/Standby Pumps
Purpose: Some chillers have 2 identical pumps for a fully redundant pumping system to enhance
uptime.
Operation: During normal operation, the pumps switch back and forth on a schedule to distribute run
time. In case of a failure with the primary pump, the standby pump will take over and circulate the
water/glycol for the application.
Optional Feature – Louvered Hail Guard Panels
Purpose: Some chillers include panels to protect the condensers from hail damage. The panels have
louvers to allow airflow while blocking hail.
