System's load includes all boilers that may run at the same time.
The temperature (°F) of condensate returns and make-up water is returned to as blend temperature.
Represents temperature (°F) that the liquid is to be heated to. Temperatures below 180°F will cause water hammer and noise. For temperatures above 205°F, a deaerator should be used.
Steam supply pressure cannot exceed 125 psig. If steam supply pressure available is above 15 psig, a pressure reducing valve must be used to reduce steam pressure down to 5-7 psig in the tank. A SPENCE Engineering Regulator comes standard with a pressure reducing valve.
Size is for a SPENCE Engineering Self-Contained Regulator (E2T14 or ET14D), normally used on Boiler Feed Units. Model E2T14 used if steam pressure at regulator is 15 psig or less. Model ET14D used if steam pressure greater than 15 psig and less than or equal to 125 psig.
