1 - Thermal rating based on a 70
o
F (21
o
C) water inlet temperature and a 50
o
F (28
o
C) temperature rise between inlet
and outlet.
2 - Flow rate is based on requirement of 1 U.S. GPM per 10 HP (1.97 kW perdm3/min) thermal dissipation.
3 - Flow rate when using Sea water is based on requirement of 1 U.S. GPM per 8 HP (1.58 kW per dm3/min) thermal
dissipation. If sea water is used as a coolant, a 500 micron filter is recommended. After use, coolant cavities must be
flushed with fresh (un-contaminated) water.
