Steam Distributing (Non-Freeze) Coils: The Accidental Coils

by Dan Jacobs, November 15, 2021

Were you aware that Steam Distributing coils or “Non-Freeze” steam coils were essentially discovered by accident? At the inception of the HVAC industry, steam coils were originally designed to be shorter in length because there was not a good way to evacuate condensate. In an effort to make steam coils longer in length, the concept of a steam coil containing a tube within a tube was invented.

Guidelines For Air Velocities

by Dan Jacobs, August 24, 2021

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.

Chilled Water Coils – Circuiting Made Easy

by Dan Jacobs, July 13, 2021

Circuiting chilled water coils is really a balancing act of tube velocity and pressure drop. In other words, think of a coil as a matrix. Each coil has a specific number of rows, and a specific number of tubes within each row.

Tips on Hand Designation & “Counter-flow”

by Dan Jacobs, June 16, 2021

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?
