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 63
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 lce 63
