Steam Distributing Coils (Non-Freeze)

by Dan Jacobs, October 1, 2024

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.

What Is Meant By A “Bank” Of Chilled Water Coils

by Dan Jacobs, July 22, 2022

For those that work with HVAC installations on a regular basis, you have run across the problem of needing to install new chilled water coils in very tight, confined areas. To avoid these issues, simply break down the single, larger coil into smaller coils. When piped together, those smaller coils are stacked into “banks” of coils in the system. If installed correctly, this “bank” should have the same performance as the larger, single coil.

Chilled Water Coils – Circuiting Made Easy

by Dan Jacobs, June 3, 2024

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.
