1218 Feedwater

Wed Feb 27 17:59:06 EST 2019

Roger,

This is just hearsay on the part of some long-forgotten to me, 
supposedly knowledgeable, commentator, but he opined that many control 
and power components on the 2300 were selected from available stationary 
power components where their normal environment included spacious areas 
with ventilation, whereas the same components were in tight, confined 
spaces on the 2300.  The higher ambient temperature on the 2300 
adversely affect the life of control valve diaphragms, pump shaft seals, 
etc.
