We are very happy to introduce the newest member of the Mechanical Equipment team, Chip Heinemann.

Chip has a long history in the commercial HVAC business. He co-founded Eitel Heinemann Mechanical Services (EHMS) in 2004, where he provided strategic planning, construction HVAC sales, and conceptual engineering services.

Over the last 14 years, they built a highly skilled and qualified mechanical contracting company that served the commercial, industrial, healthcare, and institutional industries all across the greater Chicagoland area.

Prior to EHMS, Chip was a Vice President at the V.A. Smith Company for 10 years. He has a BS in Thermal and Environmental Engineering from Southern Illinois University.

While at EHMS, Chip was a frequent customer of Mechanical Equipment. When he decided to transition to the equipment sales side of the industry, it was a no-brainer to invite him to join our team.

Dennis O’Shaughnessy, Mechanical Equipment’s founder, said, “We are thrilled to have Chip join us. He knows our business and the product lines inside and out. We’ve seen his work ethic and drive as he grew his business and knew he would be a great fit with our culture. I also think he’s a tremendous asset to our customers because he can offer firsthand knowledge from the contracting / installation perspective, and consult on projects to solve “real-world” issues that often arise on projects. He brings a lot more to the table than simply selling equipment!”

“After closing my business, I wanted to do something new, while still using my strengths and knowledge of our industry. I’ve known Dennis for a very long time and when he offered me a position, I saw it as an exciting and new opportunity. It will be fun to sit on the other side of the fence as a sales representative,” Chip said. “I know the products because I bought and installed them for so many years, and I bring a unique perspective to the team from having been on the customer side. I’m an engineer and I know how the products that Mechanical Equipment represents are best applied, because I have used them myself on many, many projects in Chicagoland, without any issues! That impressed me.”

Chip will be reaching out to our customers to introduce himself soon, so please help us welcome him on board!

Patterson-Kelley is one of our most trusted lines of heat transfer equipment like boilers and water heaters. They recently published this article on boiler turndown rates that we thought you would find it of interest.

 

Operate at Peak Efficiency

Thermal efficiency is simply the chemical energy added to the boiler divided by the energy added to the boiler water.  As more energy is transferred from the hot gas into the boiler water, the thermal efficiency increases and the temperature of the hot gas decreases.

Almost all boilers are tuned to add excess air, which ensures ideal combustion of the fuel for proper air-fuel mixing. The excess air can also prevent the burner from overheating by “pushing” the combustion flames off the burner.

When energy from the hot gasses is transferred to the boiler water, the gas temperature dips below the dew point, which causes vapor to become liquid. The energy released from the conversion is picked up by the boiler water and results in a significant boost in efficiency. Every pound of water converted into liquid adds approximately 1000 BTUs to the boiler water. However, dry flue losses and loss of vapor can result in energy loss.

Energy loss can be readily calculated if the amount of CO2 and O2 in the flue gas and the stack temperature is known.

With the evolution of boiler technology, manufacturers have found a way to offer units with multiple firing rates, and units that can modulate seamlessly between fixed low fire rates and fixed high fire rates. The fixed fire rates are defined as the boiler turndown capacities, and modulation is accomplished by reducing the air and gas flow into the boiler.

The benefit of this modulation is threefold; it reduces cycle losses, it reduces the wear on the components, and it can potentially lead to higher thermal efficiencies.

Impact of Turndown

This begs the fundamental question – wouldn’t a boiler with extreme turndowns be much more efficient than one with 5:1 turndown?  The answer to that is NO!

To achieve high turndowns, the boilers are tuned to deliver greater amounts of excess air at low firing rates to keep the burner from overheating. The additional excess air will significantly reduce the dew point of the water in the flue gas and alter the losses in the dry gas. To illustrate this effect, the example used in Figure A is updated to reflect a 20:1 turn down where the O2 is set to 11% (corresponding to a CO2 of 5.6% and 97% excess air).  The results are highlighted in Figure B below.

Note that the dew point has been lowered from 130.6° F to 117° F  and the boiler is no longer in the condensing range.  This represents a 3.7% DECREASE in overall efficiency and this is just the beginning of the bad news! 

When excess air well above 50% is used in the boiler, it impacts the stability of the combustion flame which can lead to excessive flame failures, nuisance trips and cycle losses.

The Analysis

Realistic boiler modulation rates have helped improve the overall boiler system efficiency from reduced cycle losses and increased thermal effi­ciencies. Extreme turndown produces the opposite effect. Boil­er plant designs must factor in actual (not extrap­olated) boiler efficiencies through the firing range of the equipment and matching the expected plant loads with the right boiler size selections.

At Mechanical Equipment, we make an effort to carry the products that our customers need while at the same time, the products that fit into our complete hydronic package. Since adding boilers to our product list, we felt that the accessory steam and hot water products used with boilers, would also benefit our customers, so we added the Sterling / Sterlco steam specialty product line.

Sterlco Steam Control Products

Sterling / Sterlco manufacturers a very high quality line of steam and hot water accessories such as:

  • High Pressure Thermostatic Traps
  • All sizes and types of F&T Traps
  • All sizes and types of boiler-feed pumps and systems
  • Steam Temperature Control valves
  • Inverted Bucket Traps
  • All sizes and types of condensate pumps and tanks

They are located just outside of Milwaukee, in New Berlin Wisconsin, with over 100 years in business. We’ve sold quite a bit of Sterlco product since we signed them on, and we haven’t had a single issue with any aspect of the product whatsoever!

Sterlco Steam Control Products
Most recently, we were contacted by United Airlines with a request for us to furnish two new Sterlco boiler feed systems at 1,000 gallons each, for better consistency and reliability. They were ecstatic with the results!

The biggest reason we chose to represent Sterlco, was their high quality line of boiler feed and condensate pumps. They are made with a 3450 RPM motor, to assure maximum efficiency while maintaining minimum motor horsepower. Available in a wide range of sizes, they are AMERICAN MADE with options that will meet or exceed your needs.

The new K Series 2’ low NPSH Pump is designed to pump hot condensate up to +212° F, on elevated tank units. If (or more likely “when”) a steam trap fails in the system, this unit continues to operate up to 12° higher than standard units. The added inducer increases vapor pressure and prevents the whole system failing due to pump cavitation. Stainless steel construction on the impeller and inducer, lengthens the life of the pump and offers supreme corrosion resistance. The K Series pump is energy efficient and will reduce total cost as well. It is engineered to fit / retro-fit current Sterlco boiler feed and condensate units, and is also a drop in replacement for other brands as well.

We stock most of these items year-round, so we can get them to you quickly. Give us a call today at 800-355-7061 to learn more about Sterlco’ s Steam Control Systems or any of our other great products.

The Department of Energy (DOE) has made some changes that affect commercial and industrial pump systems. To stay up to date and compliant, you might be interested in registering for this free webinar. Taco, one of our most popular manufacturers, is hosting “DOE Commercial Pump Regulations and Labeling” on Oct. 25th at 1 p.m. CST.

Did you know that 25% of currently available pumps will not be saleable as of January 27, 2020 due to new energy efficiency levels being implemented by the DOE. This webinar will cover the scope of pumps affected by the new Commercial & Industrial Pump rules, the new rating system, test methods and performance requirements. It will also explore the industry’s efforts to implement a new Energy Rating labeling program, which is similar in look-and-feel to the Energy Star appliance labels and can easily be used by utility incentive programs to incentivize the purchase of high-efficiency pumps.

Learning Objectives:

  • Understand the scope of products covered under the DOE rulemaking
  • Pump Energy Index (PEI) is the new DOE metric – what it means and how it’s applied
  • Learn the compliance timelines
  • See what the new pump label looks like and how it will help affect purchases of higher efficiency equipment

It’s why we have aligned ourselves with the best mechanical equipment manufacturers, and why we have hired and retained the best service staff.

This year we wanted to take it up a notch and thank our customers for their loyalty and support over the years. On August 17th, we held our first “customer appreciation” golf outing at the beautiful Makray Memorial Golf Course in Barrington. Over 140 of our clients showed up on a day when the weather started out looking a bit ominous. But by the time our BBQ lunch was served (burgers, brats and cold beverages) the sun was shining and the day was off to a perfect start.

The golf was excellent and all of the guests received a goody bag with lots of fun things inside. Our customers enjoyed meeting our team and networking with others. There were contests and prizes galore, including four Hole-in-one contests with a 2017 Ford F150 Pick-Up Truck as the biggest prize available. We had two longest drive contests, two closest to the pin contests, and two longest putt contests. There was a low-score contest and five team events, all overseen and scored by the club professional Don Habjan.

After some of the best golf of the summer, a terrific buffet dinner and desert was served.

If you weren’t able to make the event we hope you can next year but we do want to take the time to say thank you for your support and loyalty. If there is anything that we can help you with, please call us at 800-355-7061.
