FIN COOL®
Selection Procedure

Step 1
System flow rate (GPM) of hot liquid
Step 2
Heat transfer requirement = input energy lost to heat 1 HP = 2545 BTU/HR
Performance curves based on Inlet Temperature Difference (ITD) of 50°F ITD = (Inlet temperature of hot liquid) - (Ambient temperature of air)
If ITD is not 50°F: Heat transfer requirement = Input energy lost to heat x 50°F/ITD
Step 3
Select curve for heat exchanger model at or above heat transfer requirement

Air Velocity 2 ROW - Style B/C | 1.3 | 1 | 0.9 | 0.8 |
Plotted pressure drop (PSID) values based on viscosity of 50 SSU. If viscosity is not 50 SSU, multiply PSID value by tabulated multiplier to obtain estimate of actual PSID:
Viscosity |
PSID Multiplier |
---|---|
50 SSU | 1 |
100 SSU | 1.75 |
150 SSU | 2.3 |
200 SSU | 2.75 |
250 SSU | 3.2 |
