Hayden Industrial Products - Fin Cool Select

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
STEP 3	Select curve for heat exchanger model at or above heat transfer requirement

Fin Cool® performance charts based on air velocity of 1000 feet per minute (fpm) through the heat exchanger core. If air velocity is not 1000 fpm, multiply heat transfer requirement calculated in step 2 by tabulated multiplier before using performance curves:

	500 fpm	1000 fpm	1500 fpm	2000 fpm
Air Velocity Multiplier 1 ROW - Style A	1.2	1	0.9	0.8
Air Velocity Multiplier 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:

	50 SSU	100 SSU	150 SSU	200 SSU	250 SSU
PSID Multiplier	1	1.75	2.3	2.75	3.2
