Because of the high level of interest in Batch Ovens, we felt it was important to explain some of the differences.
USED vs. NEW – This is probably the biggest misconception out there. In most cases, the benefit from the lower cost of a used batch oven quickly fades away after you pay all of the hidden costs such as removal, repair, etc. it’s not that great of a deal. Let’s say that you find a Used 8x8x20 Batch Oven for $17,000. That sounds like a pretty good deal, until you figure in these hidden costs:
When you add up the above expenses, that Used Batch Oven will really cost you $25,750. You can buy a New Batch Oven for about $25,000. This isn’t always the case, but it happens about 80% of the time. The problem is that, by the time you find out what that Used Batch Oven will really cost you, it’s too late and you’ve already started down the road. There’s no turning back now!
The other problem, that isn’t mentioned above since you can’t put a price on it, is the cost of not having a warranty. If anything happens to your Used Batch Oven, whether it’s before or after the installation, you’re on your own and have no support.
EFFICIENCY & AIRFLOW – There have been many advancements in the Batch Oven world, and many of them are related to the efficiency of your oven’s performance. There is a direct engineering relationship between the amount of BTU’s being put into the process air of the oven, just like, there is a direct relationship to the amount of hot air that is flowing through your oven and the amount of time it takes for the oven to heat up. Don’t be fooled into simply thinking more is better! Just because the oven uses a larger burner or fan doesn’t necessarily mean that it will be more efficient.
We should also discuss how the heated air is being distributed through the oven and how it is being returned to the burner box to be re-heated. These are all important things in the way your batch oven works, and should not be messed with or tweaked in order to get a different outcome or to change the size of your oven. In other words; if you need an 8’w X 8’h X 20’l Batch Oven, you cannot take an 8′ X 8′ X 8′ Batch Oven and simply make it work by adding more panels and turning up the gas pressure or fan pulley size.
OVEN DOORS – The overall construction of your oven is very important, but don’t overlook the most important piece of construction on your oven…THE DOORS! You will be constantly opening & closing them, moving parts in and out and banging into them with carts or forklifts or both. Your Batch Oven Doors take a lot of abuse throughout the day and they need to be tough. Besides being tough, they need to be able to take a lot of abuse and not break. Let’s face it, even the toughest of equipment needs to be fixed sometimes, maybe they get bent a little or they need to be re-shimmed. If that ever happens, you don’t want some cheap Batch Oven Doors that are simply made out of more oven panels and fastened together with angle iron…you want Industrial Strength Oven Doors with good hinges that you can actually work on.
There are many other advantages and disadvantages to every equipment choice, but when it comes time to purchase a Powder Coating Batch Oven or Powder Coating Batch System you should always partner with a professional.
You can easily go out and find a used oven to purchase, and sometimes they can be removed and set it up without a problem. My experience shows that not to be the case usually, my experience shows you rarely hear about the deals that went bad because…who would brag about that! Wouldn’t you rather work with someone who has been around awhile and seen MANY different things? Someone who can share some of his knowledge and hopefully keep you from making the same mistakes that I see over and over again out there.
