Temp-Troller Industrial
Selection Procedure

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

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
