Direct Expansion & Chilled Water Cabinet Coils

There are lots of ducted cooling applications with chilled water and/or DX (Evaporator) coils where you need to add incremental cooling to an existing system. However, there is an important difference when using heating coils. Because it’s a Cabinet Coilheating coil, there is no humidification occurring or water/condensate to draw. Due to these factors, cooling coils require a little more creativity and labor to install.

At Capital Coil & Air, we have removed all of the guesswork out of the application. Capital Coil manufactures Custom Coil Cabinet sections from as small as 12” x 12” sections to as large as 54” x 90” sections. We manufacture these units in both Chilled Water and DX (Expansion), as well as in 1/2” & 5/8” copper tube coils. You have the option to select anything from (3) rows to (8) rows. Additionally, we will custom-design the Cabinet around whichever site you select. Cabinet units include both insulation & drain pans, while the supports and casing allow you to connect directly to the ductwork. We can also add a Heating Coil inside the unit for more dehumidification if needed. Cabinet Coils are perfect for either heavy or light-duty installations.

All Cabinet Coils are available on Capital Coil’s Quick-Ship Program as well. As you are probably all-too-familiar, trying to custom design coils in the field is a pain. Using Cabinet Coils will greatly ease the whole installation process. Please see our Insulated Cabinet Coil Brochure for more details on available custom sizes.

Capital Coil & Air looks forward to the chance to your coil replacement specialists. Please give us a try on your next project!

Differences Between Commercial & Industrial Coils??

The best performance you can get out of commercial coils is with copper tubes/aluminum fins. An extremely important fact to take into account is that when you change the materials of construction to an industrial coil, there’s always a drastic change in the performance. 

The explanation is really quite simple: when we build a stainless steel or 90/10 cupro-nickel coil, the materials don’t match up in terms of heat transfer to copper tubes/aluminum fins. So what does that mean? Using a chilled water coil as an example – you have a (4) row chilled water coil with copper tubes/aluminum fins, and you want to change to stainless steel. You will need to move to an (8) row coil to meet that same performance.                                                                                                                                                                          Commercial Coils

What conditions require these types of materials? The most common is with high pressure applications. Anything above 200 psig requires that you change construction materials from copper tube/aluminum fin to a special material that is able to work better under those conditions. The other instances are when you’re dealing with high temperatures or corrosive atmospheres. 

Capital Coil & Air manufactures and designs a wide assortment of heavy-duty industrial coils to withstand the environment of industrial applications.  Standard and custom designs are available for new and retrofit installations.  Our industrial coils are manufactured from quality materials that are heavier grades and thicknesses.  This ensures dependable performance and longevity, even under the most demanding conditions. While most manufacturers throw out astronomical prices or lead times that can better be explained as “months” rather than weeks, Capital Coil’s lead times are (4-5) weeks for cupro-nickel and (5) weeks for stainless steel.  

Whether it’s for boiler air preheating, pulp and paper drying process, lumber drying process, textile drying process, chemical heating process, Capital Coil & Air provides high quality industrial coils designed for easy maintenance and low operating costs.  With capabilities to build fluid coils for water, glycol, oil, and other liquids as well as refrigerant coils and steam coils for high pressures, we can easily meet all of your industrial coil requirements!

Does Your HVAC Coil Selection Program Leave You With More Questions Than Answers?

At Capital Coil & Air, we have an accurate and user-friendly coil selection program to select and choose coils. Of course, making good selections is based on having years of experience working with coils of all types and sizes, and Coil Selection Programwe at Capital Coil have that necessary expertise.

When designing a coil, the object is to balance cost and performance together, and that is one area in which we can greatly assist. We do not always choose the cheapest coil because the cheapest coil in almost never the best coil. There are always pressure drops, materials of construction, performance requirements and a host of other things that all play into good or bad coil selections. These are even more relevant in the coil replacement market!

The object is not to duplicate a problem with a coil, but to instead solve the problem and make the coil perform better and last longer. This requires problem solving and making selections that are not always “in the box”.

Part of any successful selection process is having a good selection program to help you. But what makes a program good? First and foremost, you must get the correct results, or you have bad information that is also useless. But apart from that, the selection program must be easy to navigate through. There are “red lights” and “stop signs” built into the program to keep you from making bad selections. Our selection program has most, if not all, coil configurations and styles that you’re likely to run across. We are confident that you’ll find the selection program user-friendly, helpful, and one that makes you want to do business with Capital Coil & Air.

You simply have to click here to request the program, and we will send you an email in response with an activation code and a link to download the program. Of course we are always here to assist you in any selections that you make, or to give you some engineering suggestions and recommendations. Thanks for giving us the opportunity to help you!
