Syracuse University Athletic Dome Renovation

by Dan Jacobs, April 4, 2022

The Syracuse University Dome (SU Dome), in Syracuse, NY is currently being renovated at a cost of $205 million. As part of the renovation, Capital Coil built (64) free-standing chilled water coils in sizes ranging from (33” x 93”) – (33” x 118”). All (64) coils are (8) rows with 304 stainless steel casing, increased tube wall thickness of .035”, with connections built and oriented at 90 degrees to facilitate ease of piping.

Coils and Counter-flow: 5 Common Questions

by Dan Jacobs, January 13, 2022

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.

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.
