Circulating fluid outlet Circulating fluid return port (292) (Flying-out size) (152) (Height to the bottom of the resin filter vessel) To circulating fluid outlet To circulating fluid return port r t r w q r t r e e o i r q w u y t y u r Bypass Piping Set When the circulating fluid goes below the minimum operating flow rate (as shown below), cooling capacity will be reduced and the temperature stability will be badly affected. Use the bypass piping set to ensure a circulating fluid flow rate of the minimum operating flow rate or more. Part no.
