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!

The Smart Approach to Buying HVAC Coils (and Saving Money)

HVAC coil replacement does not have to be cost prohibitive. As you are all aware, money is tight these days, and budgets for maintenance and upkeep are constantly being cut. People are asked to do more with less, so every dollar spent must be spent wisely. In our previous newsletters, we have outlined various reasons about why you should do business with Capital Coil & Air. However, one of the most compelling reasons is cost and how you spend your money.

We now live in an age where you can skip “middle men” and buy direct from a manufacturer or supplier. Think about your own life and how your own personal shopping habits have changed over the years. When was the last time you used a travel agent to book a trip? In 2020, you’re much more likely to go to Tripadvisor or an airline’s website and make travel reservations yourself. Greater access to more choices gives you the opportunity to save money in the process.

Spending money in business these days is no different. Consumers have access to more information than ever before. Consumer studies show buyers get 60% of their product information from a firm’s website before ever speaking with a sales rep. The days of an account manager or manufacturer’s representative being the sole source of information are over. Right now, you can access Capital Coil’s website and see our entire HVAC product offering, including dimensions, quick-ship programs, and our Coil Selection Program. With information at the press of a button, Capital Coil’s expert customer service will consult with you to ensure that you’re getting exactly what you need, when you need it. Working with Capital Coil & Air directly cuts out that “middle man’s” costly mark-up and saves you money without sacrificing quality. Avoiding the “middle man” and having a direct line to the manufacturer also ensures quick response times, and helps to make sure that no information gets lost in translation.

Capital Coil & Air does have a select number of exceptional representatives in a few areas, and because they are valuable assets in the HVAC industry, we are comfortable passing your project information along to those representatives. But if not in one of those areas, you are free to work with us directly.

At the end of the day, technology has allowed you as the consumer to buy smarter, faster, and cheaper. Aside from those previously mentioned “middle men” who does not want faster and cheaper? Capital Coil & Air would like the opportunity to be your “direct supplier” on present and future projects. Give us a call and test us out!
