DX Coil Replacement for Harsh, High-Humidity Mushroom Farm Environments
Kennett Square, PA is widely known as the mushroom capital of the world. It is also located just a short drive from Capital Coil & Air’s sales office in West Chester, PA. Because of that proximity, we regularly receive requests from local mushroom farms to visit their facilities and measure failing DX coils for replacement. […]
Coils and Counter-Flow: 5 Quick HVAC Questions Answered
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.
Condenser Coil Failing? Here’s Why
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.
Why Are HVAC Coils Made with Copper Tubes and Aluminum Fins?
It’s no coincidence that HVAC coils predominantly use copper tubes and aluminum fins. Copper is known to have exceptional heat transfer properties, while aluminum, although effective, does not match copper’s performance. When it comes to HVAC coils, the primary goal is either cooling or heating, which means heat transfer is a top priority. Right behind […]
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.
Why Cooling Coils Need to Be Replaced
In theory, properly engineered and maintained cooling coils should deliver 20+ years of service life. In practice, most coils are replaced prematurely. The root causes are typically operational neglect, environmental exposure, improper application, or design limitations. Below are the three primary drivers of early replacement, along with technical context. 1. Increased Air Resistance from Coil […]
Looking For A Trane Replacement Coil
If you need Trane replacement coil within a Trane system, but aren’t sure about the dimensions or decoding the model #, send this to Capital Coil & Air for pricing. On most Trane AHU’s, the AHU model #, as well as the coil or “part #”, is listed as “Service Model No Coil”. If you […]
Steam Distributing Coils (Non-Freeze)
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.
Top 5 Reasons Commercial HVAC Coils Prematurely Fail
Capital Coil & Air has come across virtually every scenario over the years in which a commercial HVAC coil had to be prematurely replaced, and we have since created an easy guide targeting the main reasons HVAC Coils prematurely fail.
Different Types of Steam Coils
There are two types of steam coils: standard steam coil, which is used in most reheat applications, and steam distributing coils, which are used in applications where the entering air temperature is below 40 F degrees.
