Guidelines For Air Velocities
Step # 1 in determining the size and performance of a coil is dependent upon understanding face velocities of air across the coil. Whether you use CCA’s coil selection program to help size the coil, or you are replacing an existing coil; the height, length and resulting velocity determine everything.
Tips on Hand Designation & “Counter-flow”
Are your water coils right hand vs. left hand? Is it looking into the face of the coil or with the air hitting you in the back of the head? What exactly is counter-flow and why is it important? Are you completely confused by why right hand vs. left hand even exists?
