Tips on Hand Designation & “Counter-flow”

by Dan Jacobs, June 1, 2024

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?

Condenser Coils Failing? Here’s probably why….

by Dan Jacobs, May 14, 2024

Very rarely do condenser coils ever freeze so the first thing you’re going to want to know is if your coil died of corrosion, old age, or possibly vibration.  Old age is obviously preferable because with a few easy dimensions, we’ll have enough to price up your duplicate coil.

Coils and Counter-flow: 5 Common Questions

by Dan Jacobs, May 7, 2024

The first thing to remember about coils and counter-flow is that chilled water coils are always built to be piped in counter-flow. This means that the air flows in the opposite direction as the water. For example, with counter-flow, the air flows through rows 1-8, while the water runs through rows 8-1. Water always travels through the coil in the opposite direction of the air; hence the term “counter-flow.”  Direct Expansion Coils (Evaporator Coils) are also piped in the same manner.

OEM Replacement Coils: Repair or Replace

by Dan Jacobs, February 6, 2024

Guidelines For Air Velocities

by Dan Jacobs, January 8, 2024

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.
