Are Your Quick-Ships Shut Down When Needed Most???

Why are quick-ships so important??

The summer season in full-swing, and your current coil supplier has suspended all Quick-Ships with little to zero notice to its customers. Does that sound familiar these days? Additionally, the clock is ticking to complete those projects that need to be done by the start of fall. In this industry, this scenario is when “Quick-Ship” availability is an absolute must. Right now, the vast majority of coil manufacturers are scrambling to complete standard orders on regular lead-times, and if by dumb-luck they are able to temporarily offer any type of expedited build, the added premiums are so astronomical that very few customers can afford to use those options.

If you need a new coil, your first inclination will probably be to call the OEM. But more times than not, they are not flexible or nimble enough to handle your emergency within an acceptable time-frame. Quick-ships are generally based on emergency conditions, and that is precisely the worst time to discover that your regular supplier has suspended Quick-Ships.

So why do so many manufacturers seem to get so overwhelmed at various point every year? In short, many manufacturers take on a glut of OEM business, or other large projects with small profit margins. In many cases they do this simply to keep the factory running during the slower periods of the year. This has the effect of delaying standard lead times, and in many cases, cancelling Quick-Ships altogether. It is very hard to do business with companies that make themselves unavailable when you need them the most.

Capital Coil’s primary duty as the leading OEM replacement coil manufacturer is to fill in those gaps and work with you to help alleviate any emergencies. Whether you need a coil in (3) weeks, or (5) days, Capital Coil has got you covered.

Capital Coil does not try to be all things to all customers, and we’re most comfortable “staying in our lane”. Our #1 goal is to ensure that we have multiple quick-ship options open all year around…even if that means turning away an order to ensure sure that our Quick-Ships are ALWAYS available!!  Quick-ships

Because Quick-Ships make up such a substantial portion of our overall business, Capital Coil has hit 99.9% of our quick-ship requests over the last (2) years. An unfortunate forklift mistake makes up the other .1%. Throughout the first 6 months of 2022, approximately 80% of all orders were/are quick-ships, and they have either all been completed on time, or are 100% on schedule.

An RFQ that sits on a desk unanswered is useless to everyone involved. If you need a quote, you’ll have your price and any required submittals that same day. It really is that simple and easy! Working with Capital Coil will remove many, if not all of the annoying and unannounced shut-downs that come with other manufacturers, so please let us help you when you need it the most!

How Should Steam Coils Be Designed??

Standard Steam Coil

Of all of  the various types of coils, steam coils operate in the most complicated ways. They are, in effect, a product of the system and controls around the coil. If not installed correctly, steam coils simply won’t work properly.

Overview:

The object of any steam coil is to have steam enter the coil as steam and exit as condensate. In a perfect scenario, the BTU load on the coil turns steam into condensate just before it’s ready to exit the coil. Under real world conditions however, condensate usually begins to form inside the tubes almost immediately. Especially when dealing with low-pressure systems, you have to find a way to evacuate the condensate from the steam coil.

Coil Pitch

A good coil manufacturer will internally pitch the steam coil within the coil casing to force the condensate toward the outlet connection. This pitch is usually 1/8 “ per lineal foot of coil.

Coil Length

If you require steam to travel 144” and make multiple passes through the coil, then, simply put, your system will not work properly. Condensate forms too early, and it cannot escape the coil. Because of this, coils cannot be too long. A better strategy is to break one long coil into two smaller coils side by side, while feeding from both sides.

Tube Diameter:

Steam Distributing coils often have to be 1  1/8 ” diameter tubes. If the BTU load on a coil is really large, then as a result, you will generate many more Lbs./hour of condensate. If the tube diameter is too small, then the condensate, which needs to evacuate, has no place to go.

Traps:

Traps are required on steam coil systems. The traps should be “float & thermostatic” type traps and be located 18 “ below the condensate connection on the steam coil. Without this, the condensate just sits in the system without any place to go.

Vacuum Breakers

Vacuum Breakers are often installed in coil systems to remove any excess condensate that may remain within the coil.

Insulated Piping:

There is no such thing as a “Condensate” Heating coil, built as a steam coil. IT DOESN’T WORK.  However, and this happens an astounding amount of times, due to the long distances the steam has to travel from the boiler to the coil, many times, the steam will enter the coil as condensate due to the piping not being insulated.

Anything that makes condensate lay in a coil is harmful to both the steam coil and the system. You will get a “water hammer” when the system is turned on and the incoming steam just blasts against the condensate. Worse than the loud and annoying sound that produces is the fact that it just destroys the steam coil. The brazing was never designed for “water hammer”.  Also, the coils do not heat properly. Have you ever seen a long coil and run your hand down its length only to feel that the entering steam end of the coil is hot but the far end is cold? More times than not, this means that condensate is laying in the coil and not allowing the steam to properly travel the length of the coil.

Steam Coils require a real expertise to design & build. We at Capital Coil have a long history in solving coil problems and building steam coils so that they work correctly the first time. Give us a call for your next job – you’ll be pleasantly surprised!
