15.3 PUMPING AND STORAGE SYSTEMS
LCE units may be equipped with 6 types of pumping systems, complete with expansion tank and buffer
tanks:
- single pump (low LP head );
- single high-head pump (HP uprated);
- standard pump and back-up pump (OR – low head);
- standard pump and back-up pump (OR – low head);
- low-head pump for combined operation (AND);
- high-head pump for combined operation (AND);
In the case of pump systems including a back-up pump, the microprocessor controls the pumps in such a
way as to equally divide the hours of operation, changing over the pumps in the event of a fault.

In the case of the dual pump - combined operation option, the advanced type of microprocessor is
mandatory, since it controls the switching on of the second pump according to the number of partialization
steps required at every moment; this means that the unit will operate in a cost-effective manner for most
of its life given that, based on well-known analyses, chillers operate under a regimen of partialization for
97% of their lifetime.
