Case Study: How Pancrete Changed a Drain Pan and a Career

We recently received some great news and a case study from one of our clients. Our product Pancrete really changed the course of his career! Thanks to Andrej Bagar of FLUXAIR Indoor Environment Solutions for this case study.

This will be a short history of my contact with Pancrete. My former boss had brought a few samples of cured Pancrete from one of the NADCA conventions a few years back and had mentioned how he thought it was an interesting product. I remember we were in the middle of a couple of large projects at the time and the matter was put aside for later. So the samples were sitting in my drawer until one of our clients asked me for a solution to a leaking drain pan. I went back to the office, did a quick online research of the product, took the sample to the customer and shortly after, I had an order for the restoration of two 9’ x 4’ badly rusted drain pans.

After my first job was done, it was quiet for a year or so until I got in contact with the chief engineer at one hospital who ended up telling me that most of their air handling units had the same problem. Good thing about the quiet period was that I had over a year long trial period, making sure that Pancrete performed as stated. After everything looked good, I felt confident to propose the same solution to the hospital.

And here I am today, restoring air handlers as my primary field with my own company. As I was working on the units, my scope of work started expanding as well, so today I am restoring and replacing other components as well, and waterproofing entire units, not just drain pans. My next project is the largest unit in the hospital.

Be Inspired: TROSA’s Two-Year Program Makes a Difference

With all the negative things going on in the world, it’s always awesome to hear of “light in a dark world.” Every year, we donate our products to an awesome program called TROSA

TROSA is a comprehensive two-year residential substance abuse recovery program in Durham, N.C. They accept substance abusers with one condition: they must have a strong desire to change their lives. TROSA’s program includes vocational training, education, counseling, mentoring, leadership training and continuing care.

The best news of all: the TROSA formula works. TROSA graduates have gone on to live healthy, productive lives as members of their communities and families.

What is even more awesome about this program is that it is available at no cost to the person receiving treatment. TROSA’s funding comes from three primary sources: revenue-generating businesses which provide vocational training for residents; donations from individuals, companies, and foundations; and modest government support. 

Controlled Release Technologies is so thankful and humbled by the fact that we have been able to support TROSA in some way. The opportunity to make a difference in someone’s life should not be passed by. To be so close to a place that changes lives is humbling. North Carolina surely has a way of helping and making a difference.

Here is just one success story out of many.  

Alan Seawell:

Over 14 years: that’s how long Alan has been at TROSA. He came as a young man whose family had tried everything to help him beat his addiction. He was divorced, the father of a young son, and facing a possible five-year prison sentence when he made the commitment to accept TROSA’s help and change his life. 

Today when Alan looks around that same campus he sees where he made his mark on TROSA. Today, Alan is TROSA’s Construction Manager and has supervised the construction of 35 housing units, two 75- person dormitories, a multipurpose gymnasium and significant renovation of offices and graduate housing. 

While Alan has left his mark, literally, on the campus, more importantly he’s left his mark in the lives of the residents who have been trained in the construction department. Alan’s commitment to his own recovery is an important example to the men who train as masons, drywall technicians, or painters in his department.

“I love being a mentor, teaching guys new things, giving them an opportunity to take pride in making something real.”

What Size HVAC Do I Need? Part 3: How to Find an Exact Number

This is the final part of a three-part series on finding the right size HVAC system for your needs. Check out part one here and part two here.

Are you in the process of purchasing a new HVAC system? Then you need to know what size is best for you! How can you find out? We’re here to help. In part one of this series, we talked about six factors to consider when choosing the right size HVAC for your home. In part two, we compared large and small systems to show you the benefits and pitfalls of both. Today, we’ll talk about how you can get the exact number for the size HVAC system you need.

How to Get an Exact Number: The Right Way

The only true way to get a perfect number in tons for your HVAC system is to contact a professional. An honest HVAC installer will take into consideration all of the factors needed to properly estimate your system and find one that works for you. There are load experts who can calculate this for you and will allow you to shop around before contacting an HVAC installer/contractor.

The Wrong Way

As you may already have heard, in this industry, there are a lot of sham contractors out for your money. One common scam is to install a larger system than is necessary. Larger systems cycle more often, causing a frequent need for repairs. On top of this, larger systems are also more expensive to install.

I recommend asking your installer (before any payments are processed) what they use to determine the load and, in turn, the size of the unit. If they have the following formula, you know you’re working with the wrong guy!

Do not use the following formula as it is extremely incorrect. If your installer uses this formula, they will install a much larger system than you need:

(Home sq. footage x 25) / 12,000

If you look at the formula, you’ll notice there is absolutely no consideration for your usage, climate or insulation. The only factor this is based on is your square footage. The number (in tons) this formula will give you is likely about 1 ton over what you actually need. For example, in this formula, a 2000 sq. ft. home would need a 4-ton unit, which is unnecessarily large in most cases. A properly-sized unit may be in the upper 2’s through mid 3’s based on your insulation, climate and usage of heat-generating electronics.

Where Can I Find a Number Online?

There are websites that can provide you with an exact number if you know what your home uses, such as:

But keep in mind, to get the most accurate reading, you’ll need someone to come out to your home and crunch numbers to help you find the best system for you. And remember, don’t fall for the “you can never have too much” saying they may try!

Thank you for reading our series! We hope we helped you understand more about how to find the best sizing for your home’s heating and air conditioning needs. Stay cool, everyone!

New Product: Resurface Chiller Tube Sheets w/ Ceramic Shield

Have you ever had something go wrong with your car?

I remember when the transmission in my truck started to go out. Man, was I upset. I thought it was the end of the world! I knew it was going to cost an arm and a leg, but instead of buying a whole new truck, I just fixed my transmission! It was much cheaper and much smarter.

Well, have you ever had to replace a chiller unit?

That can cost anywhere from $20,000 to $40,000! Yikes! But just as with cars, there’s another solution: replacing a part of it, instead of buying a whole new unit.

What causes a chiller barrel to fail?

One common cause is corrosion and erosion from high water velocity, dirt and sand particles. Chiller barrels have tube sheets on their end that are covered by an end cap. These tube sheets (like the one on the left with all the holes) can get super nasty from all the dirt and water hitting them. Nobody wants to spend thousands of dollars replacing a tube sheet when it’s much easier and cheaper to resurface it. There are plenty of tube sheet coating products on the market, but we’ve got something new!

What is it? Ceramic Shield.

Ceramic Shield is a product that resurfaces chiller barrel tube sheets and end caps. With its hard ceramic quality, this epoxy coating has a high corrosion resistance and we’ve tested it in our lab under 5 times the normal water velocity of most chillers. It’s stronger than steel and with its hard ceramic coating, you can give years back to your unit!

Is it easy to apply?

Absolutely. There is no need to fly in a technician with Ceramic Shield, because you can do the work yourself. All you need to do is remove the end cap, cork all the holes on the tube sheet, and sandblast the area. Then use a product like our Clean Bond to prevent flash rusting and provide a solid bonding surface for Ceramic Shield. Mix Ceramic Shield according to the instructions, then trowel it on, and let it cure for 36-48 hours. You only need one coat! After the product has cured, you can remove the corks, replace the end cap and put the unit back into service. The whole process should take a maximum of two days. That’s bang for your customers’ buck.

Why should I use it?

This is a great way to gain new business for your company, because many contractors don’t do work on chiller units. But with this easy-to-apply, one-coat product, why not? You can gain new business, solve a problem for your customers (who don’t want to spend thousands on new chiller units), and increase your profits.

What sets Ceramic Shield above the competition?

First, it’s a one-coat application, unlike many of our two-coat competitors. This can cut time and labor in half. It’s also less expensive and you can install it yourself without having to bring in a technician. That cuts out flight costs, hotel stays and labor that you might otherwise pay for.

Have more questions?

We would love to talk to you about this product and how it can bring in more business and help your customers. Give us a call today at 1-800-766-9057.
